Show HN: GPT-4-powered web searches for developers (phind.com)

Hi HN,

Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search.

GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a step-by-step guide complete with citations (https://phind.com/search?cache=0fecf96b-0ac9-4b65-893d-8ea57...) while Phind in default mode meanders a bit and answers the question very generally (https://phind.com/search?cache=dd1fe16f-b101-4cc8-8089-ac56d...).

GPT-4 is significantly more concise and “systematic” in its answers than our default model. It generates step-by-step instructions over 90% of the time, while our default model does not.

We’re particularly focused on ML developers, as Phind can answer questions about many recent ML libraries, papers, and technologies that ChatGPT simply cannot. Even with ChatGPT’s alpha browsing mode, Phind answers technical questions faster and in more detail.

For example, Phind running on “Expert” GPT-4 mode can concisely and correctly tell you how to run an Alpaca model using llama.cpp: (https://phind.com/search?cache=0132c27e-c876-4f87-a0e1-cc48f...). In contrast, ChatGPT-4 hallucinates and writes a make function for a fictional llama.cpp.

We still have a long way to go and would love to hear your feedback.




I've replaced 90% of my Google searches with Phind in the last few weeks. My use cases are learning a new API, debugging, generating test cases.

It's amazing. Real time saver. Just yesterday it saved me from going down an hour+ rabbit hole due to a cryptic error message. The first solution it gave me didn't work, neither did the second, but I kept pushing and in just a couple of minutes I had it sorted.

Having said that, I'm not sure I see the gain with Expert mode yet. After using it for the last couple of days, it's definitely much slower but I couldn't perceive it to be any more accurate.

Judging by your example, it looks like the main difference is that the Expert mode search returned a more relevant top result, which then the LLM heavily relied on for its answer. If search results come from bing, can you really credit that answer to Expert mode?

PS. You mention launching GPT-4 today, but the Expert Mode toggle has been there for at least a few days, I reckon? Was it not GPT-4 before?


Love to hear it. It's true that for some searches you might not notice a difference, but for complex code examples, reasoning, and debugging Expert mode does seem to be much better. We quietly launched Expert mode a few days ago on our Discord but are now telling the broader HN community about it.

We're working on making all of our searches the same quality as Expert mode while being much faster.


I'm definitely giving this a try sometime soon. I had an idea back when it was just GPT-3 out there, to use LLM-generated embeddings as part of a search ranking function. I'm betting that's roughly how Expert mode works, right?

Edit: Just had another thought. You could use the output of a normal search algorithm to feed the LLM targeted context, which it could then use to come up with a better answer than it would without the extra background. Yeah, I like that.

Although, I will say I asked it about writing a lisp interpreter in Python, because I was just tooling around with such a thing a little while ago for funsies. It essentially pointed me to Peter Norvig's two articles on the subject, which, unfortunately, both feature code that either doesn't run properly or doesn't run right at all. I was disappointed.


We do use the output of a "normal" search algorithm to feed our LLM context :)

Did you use Expert mode for your search? Only Expert mode is GPT-4 and its code quality is vastly superior to that of the default mode.


I'm a beginner, so I'm unable to tell if it's hallucinating or not. Do you find it hallucinates or is incorrect? I'm wary of noting stuff down and remember wrong things an don't want to drill 2 levels deep for each question


I've been using ChatGPT 4 the past couple weeks and also Phind just last night with a new library version. While yes, i did find that Phind was wrong a lot (though i don't think it was fully hallucinations, just wrong library version combinations), i think there's a more important point to be made.

Unless we get a very near breakthrough on self-validating accuracy of these models or models+plugin combinations, i suspect it may be a useful skill to learn to use LLMs to explore ideas even when hallucination is a risk.

Ie searching with Google is a skill we have to acquire. Validating results from Google is yet another skill. Likewise i feel it could be very useful to find a way to use LLMs in a way where you get the benefits while managing to mitigate the risk.

For me these days that usually translates to low risk environments. Things i can validate easily. ChatGPT was a good starting off point for researching ideas. It's also very useful to know how niche your subject matter is. The less results you find on Google for your specific edge case the more likely ChatGPT will struggle to have real or complete thoughts on the matter.

Likewise i imagine similarly this is true for Phind. Yea, it can search the web, but as my tests last night showed it still happily strings together incorrect data. Old library versions, notably. I'd say "Given Library 1.15, how do i do X?". It did eventually give me the right answer, but it happily wrote up coding examples that were a mix of library versions.

I imagine Phind will, to me, be similarly useful (if not more?) than ChatGPT, but you really have to be aware of what it might do wrong. .. because it will, heh.


We definitely still have work to do in this area and the feedback we've gotten here is incredibly helpful. Having the AI be explicitly aware of specific library versions so it doesn't mix-and-match is a high priority.


I just tried it for a problem I solved in Azure Data Explorer and it solved it by making up some APIs that don't exist. It got close to how I solved the problem but cheated even with Expert mode enabled.


Seems like accuracy is the next killer feature for LLM search and teaching, will try again in 6 months


What a time to be alive where we likely need wait only a few months for the next big hurdle to be accomplished.

Exhilarating and terrifying at the same time.


I dunno about that in this case. The "confidently incorrect" problem seems inherent to the underlying algorithm to me. If it were solved, I suspect that would be a paradigm shift of the sort that happens on the years scale at best.


Yes, the "confidently incorrect" issue will be a tough nut to crack for the current spate of generative text models. LLMs have no ability to analyze a body of text and determine anything about it (e.g. how likely it is to be true); they are clever but at bottom can only extrapolate from patterns found in the training data. If no one has said anything like "X, and I'm 78% certain about it", then it's tough to imagine how an LLM could generate reasonably correct probability estimates.


What you're alluding to is calibration and base gpt-4 had excellent calibration before RlHF.


It seems to be sort of a bit wrong more often than it hallucinates.

I've had it straight up invent a library that doesn't exist once, but that seems to be quite rare and you need to be deep in the weeds with a rare problem domain to get that.

More often I ask it how to do something, and it sort of provides an answer, but not quite. So I point out the flaw, and it fixes it, but not quite. Rinse and repeat. After anywhere between 4-10 iterations it's usually quite good. The experience is like code reviewing a really apologetic and endlessly patient junior developer.

Although I think what might be a beginner's saving grace is that it seems to be better at beginner questions than advanced questions, since there are more of them in the training data.


google who?


its a verb now, I search at phind.com


Passes my smell test, which is to ask "how do I migrate my swift composable architecture project to structured concurrency". This uses 2 things that GPT-4 doesn't know about yet: Swift 5.5+ and composable architecture 1.0+

It pulled in information from both Apple, the composable architecture folks and a swift forums post to give a really nice answer.

Well done! I'll be using this a lot.

I'd love to know more about how you pull in relevant text from web results for it to use in answers.


That's our secret sauce :)

We've built out a decently complex pipeline for this, but a lot of the magic has to do with the specific embedding model we've trained to know what text is relevant to feed in and what text isn't.


This is a really cool tool. Have you considered filtering known blog-spam/low-quality content mill/SEO'ed garbage type sites (ie: GeeksForGeeks, W3Schools, TutorialsPoint)? That would make me definitely jump on this, and even pay for a subscription. I spend way too much time having to scroll down Google past all this junk before I hit the official documentation for module I'm using.


we do some filtering ourselves, but you can specify your own custom filters at https://phind.com/filters


This is great, going to see how this fares tomorrow as a replacement for Google.


If you use duckduckgo there's the ddg-filter firefox plugin that lets you block domains. I use it to block exactly the low quality domains you mention.

Maybe there are similar plugins for other search engines as well...



i don't think they really need to...maybe for citations but for training if the content is the same on site A and B it doesn't matter which one it pulled from.

that said.. if the content itself is bad then that'd be a problem. we'll probably start seeing that, sites designed to poison LLMs.



Is this website satire or an honest/evil attempt to poison the well?

Oh....I see, at the bottom, says satire specifically. Or rather "sAItire". Cute.

Didn't waste any time putting that up.


You can always remove your hated sites on Google search as well. For example:

Python list -w3schools

It will not include links contain the text


I know, it's just irritating to have to do that, or have an extension do it. I would be happy to support a search engine that lets me filter out unwanted crud.


Any pointers on how to build custom embedding ? I am working on a specialized domain where words may mean different things than rest of the world. I want to create my own embeddings, which I suspect would help. Any pointers ?


Doesn’t ChatGPT bring that through plug-ins? Also bing chat


>This uses 2 things that GPT-4 doesn't know about yet: Swift 5.5+ and composable architecture 1.0+

Conversely, I asked it to tell me the current version of .Net Core. It returned version 6, the same answer as GPT-4, but the right had frame did return results indicating that version 7 is in fact the current release.


I asked it this question[1],

    I traverse a maze using a basic A* implementation (using the Manhattan distance metric). However, after the traversal, I would like to find out what wall would give me the best alternative path. Apart from removing every block and re-running A* on the maze, what's a more clever and elegant solution?
a question I asked on SO over 10 years ago. The SO thread includes working code and very friendly explanations and discussion. The answer Phind gives is the following[2]. It tells me to use D*-lite (complete overkill), Theta* (totally wrong), or "Adaptive-A*" (not sure if that's an actual thing, all I can find is a random paper).

I was working on this in the context of a game I was making at the time, and while this is certainly a hard (and maybe rare) question, it's still on the level of CS undergrad.

[1] https://stackoverflow.com/questions/2489672/removing-the-obs...

[2] https://www.phind.com/search?cache=d08cd0e7-4aa8-4d75-b1cd-7...


Here you can apply the most common technique for such problems, which is to create a graph whose vertices are pairs made of a vertex of the original graph, plus the "state" of the traversal (or in other words, the essential information about the path used to reach the vertex).

In this case, the state is the number of walls passed, so just create a graph made of (v, k) pairs where for adjacent v and w in the grid, (v, k) connects to (w, k) if there is no wall, and it connects to (w, k + 1) if there is a wall.

Then run A*, finding the shortest path from (start, 0) to (end, 1), reconstruct the path and look at where it transitions from a (v, 0) to a (w, 1) and then return the wall between v and w.

You can use this for all sorts of other constraints, like finding a path that only changes direction up to N times, or a path where you don't get eaten by the monster moving deterministically (in this case the state is the monster position), or a path where you spend up to N time underwater consecutively, etc.

But GPT-4 seems very bad at solving problems, so even though this is an easy problem, it's not unexpected that it would not come up with this solution.


> find out what wall would give me the best alternative path

This, specifically, and the question as a whole are hard to parse as a human. Before clicking through to the SO link (where there seems to be a lot more context), I wouldn't have guessed the problem you were trying to solve.

I'm curious why you changed the prompt at all? Was it to get the model to avoid your question's SO page?


Really?

Just that quote alone seemed pretty clear to me, and it becomes even clearer as you read the rest of the prompt.


I found it quite incomprehensible. Particularly the most important bit:

> after the traversal, I would like to find out what wall would give me the best alternative path

Is he talking about adding a wall? Or removing a wall?


Personally, I'd find that prompt difficult to understand without the title of the stackoverflow question. Did you include that?


Even just writing the title and nothing else gives more interesting answer:

https://www.phind.com/search?cache=0e527db3-7740-470e-bba6-5...


No, but I'm not sure if it would make much of a difference, feel free to try it out.


> it's still on the level of CS undergrad.

I have 21 years of professional experience as a software engineer with a bachelor in CS before that and have never heard of "Manhattan distance metric", "A* implementation", "D*-lite" or "Theta*" until now. I'm sure if I'd read the explanation of those things I'd eventually figure it out (and I'm sure an LLM would make more sense if fed descriptions instead of gobbledygook.


Wait… you’ve never heard of A*?


Same. I didn’t learn those things until my Grad CS program.


LLMs are notoriously bad at puzzle solving and you gave it a prompt that was very sparse on details. What did you expect?


Not only LLMs. I couldn't answer that prompt.


The SO answer is pretty good and probably the most generalizable pathfinding solution.

My first thought was to also run A* from the end to the start. This would allow you to look at each wall in the maze and check if the A* cost from the start + A* cost from the end < best current path. In my opinion, this would result in simpler code than the SO solution.


An equivalent formulation to the SO solution with a simple implementation is to double the vertices and edges in the graph G by making a duplicate parallel universe G'. One can always move from v in G to its corresponding v' in G' at zero cost, but there is also a cost-1 edge from vertex u in G to v' in G' whenever u and v are separated by a wall. Once one crosses into G', there is no going back.

One can pass the new graph, G ∪ G' plus all the intermediate edges, into the already existing A* implementation to search for an optimal s-t' path. This works as long as the heuristic for v is also admissible for v', but most are. I think all three of these algorithms could in principle run into problems for certain uncommon admissible heuristics.


> My first thought was to also run A* from the end to the start. This would allow you to look at each wall in the maze and check if the A* cost from the start + A* cost from the end < best current path. In my opinion, this would result in simpler code than the SO solution.

Yeah, this is the naive O(n^n) solution. Remove every wall, see what path is the cheapest. Having come up with this, I specifically wanted a more elegant solution. As it turns out, you can do it in one shot (but it's a bit tricky).


I am not explaining an O(n^n) solution. Its an O(E) time and O(V) space solution just like normal A*.

I am assuming you are saving the initial A*run and the subsequent reverse run. Then `A* cost from the start + A* cost from the end < best current path` is a O(1) time operation that occurs a maximum of once per edge.


Maybe I'm totally misunderstanding, but figuring out the "best current path" means re-running A* every time you break a wall, as removing arbitrary walls can give you a totally new path to the goal; to wit, it might be a path not even originally visited by A*. And you have to do that every time you try out a wall candidate, so to me this appears to be quadratic(ish) complexity.

(But maybe this is exactly what the SO answer does "under the hood," to be honest, I haven't done a deep complexity analysis of it and I haven't thought about this problem in ages.)


> Maybe I'm totally misunderstanding, but figuring out the "best current path" means re-running A* every time you break a wall, as removing arbitrary walls can give you a totally new path to the goal; to wit, it might be a path not even originally visited by A*. And you have to do that every time you try out a wall candidate, so to me this appears to be quadratic(ish) complexity.

My algorithm should obviously work using Dijkstra's algorithm instead of A*. You just have to make sure ALL nodes are explored. You don't have to run searches per node.

Why it works with A* too is MUCH more subtle. In fact it only works if your A* implementation is fair to all likely shortest paths; most implementations do not guarantee fairness. You can enforce fairness by changing your heuristic to be only 0.9999 * Manhattan distance. Fairness ensures that any path that will be the best path after deleting a wall will have a cost recorded for both sides of the wall.

> (But maybe this is exactly what the SO answer does "under the hood," to be honest, I haven't done a deep complexity analysis of it.)

If the original maze is 2D with coordinates (x,y), the SO algorithm is essentially searching in a 3D maze with coordinates `(x,y, number of times crossed a wall)` and directional edges from `(x,y,n) to (x+dx,y+dy,n+1)` if there is a wall there.*


> My algorithm should obviously work using Dijkstra's algorithm instead of A*. You just have to make sure ALL nodes are explored.

Gotcha, yeah, that's what I was thinking. You lose basically all of A-star's optimization because you do need all nodes explored (turning it into pure Dijkstra). Makes total sense.

> If the original maze is 2D with coordinates (x,y), the SO algorithm is essentially searching in a 3D maze with coordinates

That's a neat way of looking at that answer, cool insight!


I asked OpenAI that exact question, this is what it said:

> One approach to finding the wall that would give you the best alternative path without having to remove every block and re-run A* is to use the concept of "edge weights."

> When you first run A* to traverse the maze, you can assign each edge a weight equal to the distance between the two adjacent nodes, which is equal to the Manhattan distance in your case. Once you have completed the traversal, you can go through each edge of the path that A* has found and temporarily increase its weight by some factor. Then, you can run A* again, but this time the pathfinder will prefer alternative paths that do not use those edges that have been "blocked" by the increased weight.

> By gradually increasing the weight of each edge one at a time, you can determine which wall would give you the best alternative path without having to re-run A* on the entire maze every time. You can also use a binary search-like approach to speed up the process.

> Here's some pseudocode for this approach:

    path = A_star(start_node, goal_node, edge_weights)
    
    for edge in path:
        original_weight = edge_weights[edge]
        edge_weights[edge] = original_weight * factor
        new_path = A_star(start_node, goal_node, edge_weights)
        if new_path is better than path:
            best_wall = edge
            path = new_path
        edge_weights[edge] = original_weight
> In this pseudocode, factor is the amount by which you increase the weight of each edge, and better than is some metric for determining whether a path is better than another (e.g., if it is shorter or has fewer turns).

> Note that the syntax and semantics of Go are quite different from Lua, so this is not a direct translation. However, the logic should be equivalent, and the Go code should be easy to understand if you are familiar with the original Lua code.

Finally: Show the declaration of the AStar struct.

> Sure! Here is an example declaration of an AStar struct in Go:

    type AStar struct {
        startNode   Node
        goalNode    Node
        edgeWeights map[Edge]float64

    startNode: a Node struct representing the starting node of the pathfinding search.
    goalNode: a Node struct representing the goal node of the search.
    edgeWeights: a map from Edge structs to float64 values representing the weights of each edge in the graph.
> Note that this is just an example, and the actual definition of the AStar struct may depend on the specific implementation of the pathfinding algorithm. The Node and Edge structs may also need to be defined separately, depending on how they are used in the implementation.

And as a cherry on top: Inline comments in the AStar struct.

> Sure, here's an example of adding inline comments to the AStar struct I defined earlier:

    type AStar struct {
        startNode   Node                   // The starting node of the pathfinding search.
        goalNode    Node                   // The goal node of the search.
        edgeWeights map[Edge]float64       // A map from edges to their weights in the graph.
    }
> In this example, I added comments to explain the purpose of each field in the AStar struct. The comments describe what each field represents and what it is used for in the pathfinding algorithm. By adding comments to the struct definition, it makes it easier for others to understand the role of each field in the codebase.


> When you first run A* to traverse the maze, you can assign each edge a weight equal to the distance between the two adjacent nodes, which is equal to the Manhattan distance in your case.

Then, you can run A* again, but this time the pathfinder will prefer alternative paths that do not use those edges that have been "blocked" by the increased weight.

Yeah, this is wrong for two reasons. First, it's actually doing things backwards (you would decrease the cost of a wall, you wouldn't need to block any path). And second, it's still predicated on re-running A* after modifying costs (and comparing it with our original path), getting us back to O(n^n).

This is more evidence that AI models are good at regurgitating, but not great at reasoning. GPT-4 probably only saw this problem once or twice (since it was trained on the Pile, which includes all of SO, including my original question), but not enough times to understand what the solution is (or even what you're asking, for that matter).


The unfortunate part is that OpenAI cannot answer a question “show me most relevant stackoverflow links for my original question”.

Edit: however, I went on and grilled it further.

Question: Rewrite the golang code to solve the maze in constant time.

> I'm sorry, but it is not possible to solve a maze in constant time, as the time complexity of the problem depends on the size of the maze and the complexity of the search algorithm used.

> The A* algorithm and its variants are some of the most efficient and widely used algorithms for maze pathfinding, as they can provide near-optimal solutions in a reasonable amount of time. However, they still have a time complexity that is exponential in the worst case.

> There are other algorithms that can solve certain types of mazes faster than A, such as maze-solving algorithms that rely on distance transforms, flood fills, or topological sorting. However, these algorithms are typically specialized and may not work for all types of mazes.

> In summary, it is not possible to solve a general maze in constant time, but there are specialized algorithms that can solve certain types of mazes faster than A.

A couple of attempts to rephrase make the GPT a bit apologetic. It claims it's not possible to do anything about, eventually, when asked to solve the maze of size 20 times 20, it replies:

> With a maze size of 20x20, it is likely that the performance of the A* algorithm is already sufficient for practical purposes. However, if you encounter performance issues or have specific constraints that require faster solutions, you can consider implementing these optimization techniques.

So I ask it: What optimization techniques I could implement?

> There are several optimization techniques that can be implemented to improve the performance of the A* algorithm or other maze-solving algorithms. Here are some examples:

    Use a more informed heuristic: The Manhattan distance heuristic used in the original code is a good general-purpose heuristic, but it may not be the most efficient for all maze configurations. Using a more informed heuristic, such as Euclidean distance or diagonal distance, can lead to faster convergence and fewer nodes being explored.

    Implement early termination: If you only need a suboptimal solution or are willing to tolerate some error in the solution, you can terminate the search early once a "good enough" solution has been found. For example, you can set a maximum number of nodes to explore or a maximum search depth.

    Prune search space: If you know some parts of the maze are not relevant to the solution, you can exclude those parts from the search space to reduce the number of nodes that need to be explored. For example, if you know the goal is located in a certain region of the maze, you can exclude nodes that are outside of that region from the search space.

    Use a better data structure: The performance of the A* algorithm is heavily dependent on the data structure used to store the open and closed sets. Using a more efficient data structure, such as a binary heap or Fibonacci heap, can speed up the algorithm.

    Parallelize the search: If you have access to multiple processing units, you can split the search space into multiple parts and run the A* algorithm in parallel. This can significantly reduce the search time, especially for large mazes.
> These techniques are not mutually exclusive, and you can combine them in different ways to achieve better performance. However, keep in mind that the optimal combination of techniques will depend on the specifics of the maze-solving problem and the available computational resources.

I still find it pretty good. It also proves my point I was making somewhere else. The challenge in applying GPT to software problems is knowing what to ask next and verifying that it gave a correct answer - as in, one needs to understand the problem without blindly trusting that what it said was right.


I tested it out and got some pretty good results - marginally better than GPT4, which is a high bar!

It strikes me that we’ve been clamoring that a better Google needed to exist, and after 20 years, it looks like we actually have one. Albeit right now it’s only better some of the time and only marginally better, and of course it might not be phind that actually takes a whack at Google… but it strikes me as an exciting inflection point.


Google has non-aligned incentives with users and the gulf has been growing. Showing me the best answer is not the goal, showing me an ad is. I’m ready and willing to pay somebody who has a clear incentive to give me correct answers.


> The goals of the advertising business model do not always correspond to providing quality search to users.

- Sergey Brin and Lawrence Page, The Anatomy of a Large-Scale Hypertextual Web Search Engine


That explains why there are more ads, but they still have incentive to improve their search results. They've been using AI for this for years and are even more motivated now.

The problem seems to be that the web itself is getting worse due to SEO. Maybe more AI improvements will overcome that?


That’s my point: I want an ANSWER not a LINK. They are incentives to provide the best LINK but not the best ANSWER.

Whereas this product gives answers. Which is why I’m liking it a lot!


Google's been working on that for a bit more than a decade [1]. Presumably they're trying harder now.

I like getting answers, but I also want links to sources so I can see where they got it from.

I think problem is here that they hit antitrust regulators if they start giving ANSWERS instead of links.

SEO will just start to target AI's.. maybe even using AI's to target AI's. The next arms race may be AI vs AI.


I don’t think it’s that easy. You get little feedback about traffic and getting an AI to accurately repeat your ad would be difficult, so this sort of SEO would be much less profitable. It’s too indirect.

Rather than being like advertising, maybe it would be more like PR where your target is journalists and it only indirectly reaches readers?


Well, I am using ChatGPT as a pocket keto nutritionist and it is recommending an actual product brands quite often. Not sure if this is intentional or just learned behavior.


like virus-antivirus


Maybe more AI? Surely you mean MOAR AI!!!?!


Thank you! We still have a lot of work to do, of course, and the feedback we get here will directly improve the service.


A better than google has existed for a while now. A new generation of web tools is what we've been asking for.


I'm sorry but what are you referring as better than google?


Kagi, for me


A search engine which requires me to have an account and give them my email address?

No thanks.


How do you think a search engine whose incentive isn't getting you to click ads can make money?


Volume.

/s


Not just that, they even ask for money! Companies these days...


It amuses me that not 5 comments up this very same chain there's someone saying they'd happily pay for a Google competitor which is even marginally better.


Do you not have a Google account?


You don't need one to perform a search.

And also, no I don't. I also don't have an Apple, Microsoft, Amazon, or other FAANG account.


I'll never understand why privacy minded people (i assume you are, given your aversion to accounts) also seem commonly dependent on supporting the Ad empires which are primarily responsible for the privacy issues of today.

Eg, you should be supporting search engines that respect privacy and offer clear incentives (read: services you pay for) not using Ad dependent services like Google. No?


So, who pays for this?

This seems to be extremely expensive and somebody is footing the bill — this immediately raises questions as to how sustainable this is. I'm worried that I can't find the "Pricing" link on the home page.

EDIT: I'm actually OK with paying, I'm just worried whenever I see a service with an expensive (GPT-4 is expensive) backend and no pricing. There is no way that can continue indefinitely.


I'd also like to ask what's the logic behind not disclosing their business model? Is it because:

a) It doesn't exist yet / more data about usage is needed (ad supported vs paid)

b) The price would be too high for most to start depending on this tool, hence this is a trick to crush competition and force users to pay higher price later

c) It's already known that the product is not sustainable


d) They plan to be bought by Google and make a big exit.


Hopefully it's free for now to gather users, at which point they'll introduce a paywall. If it keeps working as well as it is so far, and remains private and free from ads, I really would not mind paying for this service.

Especially as it keeps the company motives aligned with the users', i.e. providing good search results rather than showing as many ads as possible.


There will always be a free version. We'll introduce a ChatGPT-style "Pro" tier where you can ask longer questions and paste in more code, faster/better models, etc.


What is chatgpt-turbo api pricing like .0001 pre 1k tokens, your paying more in workers salary at the moment.


$0.002/1k tokens, gpt4 is $0.03/1k tokens read and $0.06/1k tokens written.


[flagged]


their ad business...


I just tried this on questions I had about archery and bow design. It was immediately useful in highlighting and summarizing sources into something coherent while citing sources for deeper study.

On the other hand, when I asked it to tell me the difference between spine weight of wooden arrows and spine numbers on carbon arrows, it was not as useful. That is because no one has ever written an article about it, and when I was looking for that manually, I had to find that answer by inferring from a technical PDF. (The answer starts with, spine weight on wooden arrows do not directly measure deflection, and was created by a trade association, rather than the spine deflection numbers designed by an organization that standardizes weights and measures of materials for engineers).

The low hanging fruit here may be to ingest and summarize pdfs and papers.


There is an AI search engine for research papers, Elicit [1]. I've tried your question about arrows but it didn't return anything useful.

[1] https://elicit.org/


unfortunately elicit doesn't extract "meaning" from papers and let you "ask" it (yet)



From a usability point of view, it does a better job than Vanilla ChatGPT however just like chatGPT, it can also actually waste times with false information.

Context: I have a piece of Druid SQL code that a coworker wanted to debug. I asked Phind to help me debug it and provided it all the context. Phind made an assertion about a possible bug in my code and suggested a variation. However when I pressed it to explain the anomaly it went about in circles. When I followed up, it veered off course with an apology and a totally irrelevant answer.

>I apologize for any confusion caused. The SELECT MAX("N_logins") and SELECT MAX(res."N_logins") statements are the same in terms of functionality.

>In the context provided [Source 2], these SELECT statements are not related to the Druid SQL query discussed earlier. Rather, they are related to the limits.conf file in Linux, which specifies system resource limits for users and processes.

Understandably it's just a limitation of the current LLM's resoning abilities, somehting you'd uncover by prompting them to play a game of Tic Tac Toe


So, a "Prompt Engineer" will also need the skill of "awareness of proximity to the edge of the time-saving cliff" or "perfect-is-the-enemy-of-good detection".

Are they expected to be able to justify their answers?


Sort of. I’m not the guy you asked, but in our work we’ve had trouble making good use of GPT for most things. On one hand it’s been a powerful tool for non-developers, and it’s helped a lot of our more technically inclined employees to automate part of their workflows (and maintain the automation on their own) in a way that no “no-code” solution has ever done before. For developers, however, it’s been giving so many terrible results that it’s not really been too different than simply using a regular search engine. Sometimes it’s much faster, but other times the lack of “metadata” and “other opinions” like you may find on a site like StackOverflow through time stamps and comments have made it significantly slower.

Anyway, getting back to the sort of part of my answer to you. We’ve had an issue where junior engineers trust GPT a little too much. This is more a psychological I suppose, but where they might not take what they find by “google programming” for granted, they are much more likely to believe that what GPT is telling them is correct. Which can be an issue when what GPT is telling then isn’t correct. Where our more senior engineers will laugh at it, and correct it’s mistakes, our juniors will trust it.

I’ll give you one example, we had a new programmer pull some information from a web-service and have GPT help them handle the json. GPT told the developer to disable our rules linter and handle the json dynamically, doing something like items.items[0].haps, and other such things. Which works, until it doesn’t. You can scoff at us for using a lot of Typescript on the backend, and we certainly shouldn’t have allowed this to ever get build in our automation, but that would still create something that might cause some really funny errors down the line. I know, because part of why I’m there is because the organisation used to do these things all the time, and it’s lead to a lot of “funny” things they needs to be cleaned up.

Anyway, this isn’t necessarily a criticism of GPT, because it still does other things well, but it is a risk you need to consider, because I do think someone is going to be able to justify those answers you talk about, and if it’s not GPT then it’ll have to be the developer who uses GPT. In many cases it won’t be an issue, because we live in a world that’s sort of used to IT not working all the time, but you probably wouldn’t want your medical software to be written in this manner.


I think it's in the same area as car "autopilots". Just like you can't give such vehicle to someone who can't drive by themselves, you can't expect it will make junior into a senior. It's not really able to extend your possibilities beyond what would be possible with enough google and studying documentation. It can save your time and effort though.


:) oh it will be written like that and has been written like that. Dont google for the number of unnecessary brain surgeries that have happened cause buggy mri software highlights tumors were there are none.

No one will consider the risk under deadline pressure. The deeper down a tech stack you go barely anyone knows what the hell is going on anymore, and or how to fix it, precisely because of half baked code added in this fashion, which accumulates over time.

At the end of the day dealing with blackbox tech is similar to dealing with ppl or groups of ppl behaving in strange inefficient ways.


It is somewhat my job to deep dive legacy problems, and often that does take an understanding of the full stack. But I am finding more challenges in newer frameworks, where "magic" is no longer a code smell, generated code is the norm, no one considered debugging and you can't always reasonably dive down a stack.

I imagine that will be much worse when you can't expect the code to have considered human readability at all.


Yup generated code is spreading like cancer. You kind of have to develop an "empathy" for the system, just like with broken humans who cant be fixed. How are you feeling today mr.blackbox? Feeling a bit lethargic? Want a reboot?


Last time I used large amount of generated code, it was pristine and easy to debug. ( Java ) What do you have in mind


I find it quite painful when code generation is used to generate plugin glue code for bigger frameworks. The reason is that it stops being searchable as function names become programmatically generated, and code changes based on any number of magic configurations or state. That is also why some meta-programming is hard to debug.

You need to reverse engineer the generators to figure out how to find the code that's actually running, in bigger applications that's a pain in the butt.


Ok. Yes absolutely. Actually I had that experience as well and I had to learn the generation logic. Waste of time.

I had good experience when the code is generated, and eventually updated automatically but for other shape and purpose it’s normal code. The generated code goes in version control.

So really it’s a scaffolding operation. But still, I was impress by the quality and ever cleaverness of the generated code. ( because the generator was written with a unique, specific target in mind )


Only if they actually know how to code, since if they do not then there is no point at which it is faster for them to do it.

That's where I am struggling to reconcile the new roles AI enables. Do we still need to be software experts? If so, usually I already know what to write, so why bother having an intermediate step. I never think to myself, I should delegate this task I am half way through to a junior. That's harder than just finishing it.


> Are they expected to be able to justify their answers?

I hear this question a lot, and I think it's phrased wrong. There's certain problems that require accuracy, high quality, or confidence in reasoning. ChatGPT is ill suited for those problems. Other problems can tolerate poor accuracy, and ChatGPT will be suitable for those problems.

I wouldn't want my doctor using ChatGPT. But if a history game used ChatGPT to show historical quotes on a loading screen, I'd be OK if some were inaccurate or misattributed.

The expectation comes from the problem you're trying to solve. As we get a better understanding of ChatGPT limits our expectations will get better aligned.


Very impressed. Seen a lot of AI stuff coming out but this is:

* Fast

* Works even with HN hug of death

* Useful for my daily flow (I mix chat gpt with google searches)

I tried “can $myname code typescript” and got a great answer.

Love it.

Concerns

* Will it stay around

* Who is paying. I don’t mind a monthly subscription model but >$20 might be hard to justify

* Privacy

Will trial for 14 days then may recommend to the team!


> * Privacy

Considering it is using GPT-4 API, you can take for granted that at least OpenAI is collecting your data. Not sure how Microsoft deal with OpenAI works, but it is possible they also have access to it.


Looks like it went down

"The inference service may be temporarily unavailable - we have alerts for this and will be fixing it soon."


no issue here


This is exactly what I want the future of search to be-- give me some AI generated summaries / snippets / guides but also the sources that were used to come up with that response.

More confirmation of just how bad this mode of operation will be to Google's traditional business


Which is what Bing Chat has been doing for a while now?


Phind is just a website. You don't need do download a whole new browser to use it.


I’m using it in Firefox, there’s a extension for that.


You can use Bingchat in FF? Which extension?


Asked Phind.com (copy pasted your comment) and got this https://addons.mozilla.org/en-US/firefox/addon/bing-chat-for...


Just set a User Agent that fools them into thinking you're using Edge:

Thanks for the tip.


I am just saying this is not new.


as content creator this makes me not wanting to create any new content, in fact this year I slowed down a lot, probably I'm going to a complete halt.


Why? Genuinely asking.

As a software engineer this all is very inspiring. I’m tickled and excited to do things again. I’m also learning deep learning and statistics and having a blast with toy projects.


How come? Genuinely curious.


This works about 10% of the time for me. 90% of the time this is what I see:

"The inference service may be temporarily unavailable - we have alerts for this and will be fixing it soon.

You can try the regenerate button in a few moments.

If your query still does not work, you can try searching this on Google or DuckDuckGo.

You can also prefix your question with !g or !ddg shortcuts. You may have to enable popups for this to work."


Just tried it with a PHP question regarding type safety, and it completely made up some lovely syntax I wish the language had, but doesn’t. It got lots of things right, but that one crucial detail wrong.

That makes it the same dangerous tool as ChatGPT that is useful to experienced coders, but utterly disastrous for newcomers.

I think if you are more specific , you should get a much better response.

I tried it with

Using php 8.1 and the static analyzer psalm, how can i specify template parameters for newly constructed classes?

and got a very good result including detailed explanations


Oh yeah? I get the following delightful but equally wrong snippet:

>Another way to achieve a similar effect is to use PHP's built-in generics feature. This feature was introduced in PHP 8.0 and allows you to specify the type of a class property or method argument as a generic type. Here's an example:

  class MyList<T> {
      /** @var array<T> */
      private $items = [];
  
      public function add(T $item): void {
          $this->items[] = $item;
      }
  
      public function get(int $index): T {
          return $this->items[$index];
      }
  }
> In this example, we use the <T> syntax to specify that MyList is generic and that it has a type parameter T. We then use the T type in the same way as before to specify the type of the $items property and the add and get methods.

> Using generics in this way has the advantage of being built into PHP, so you don't need to use any external libraries or tools. However, it can be a bit more verbose than using PHPDoc comments, and it doesn't provide the same level of type checking as Psalm.


If its using GPT-4, wouldn't this incur a very expensive bill? Especially given that the search is free? That aside, I tried using it on "how to stop mysql service in mac", and it gave me really good answers detailing different alternatives depending on what i used to install mysql. It's a lot better than what i could find on google search. So this is really awesome :)


This is amazing! I've been fed up with the SEO soup google has been serving up the last few years. There are good results on there, but you need to dig to find the good bits you care about. For code debugging stack exchange is often my go to, but for concise code examples and good explanation of how to do something with code, I really like the way phind summarizes the information in a straightforward way.

Makes me want to start coding more in my spare time, as my biggest hurdle is often finding information about how to start or how to do something more complex. I see it as a great way to learn. If it hallucinates something it's not the end of the world, and I'll usually catch it pretty fast.


Whoa. I asked it how to use Facebook's new Segment Anything model on a specific use case in microbiology and it spat out all the code I needed.

What in the world?! This is dark magic.


The magic is GPT4. Basically show GPT4 the right context, which today you can use a good retriever model for (I'm sure they also fine-tuned it, probably on GPT4 generated data...), a little bit of good prompt engineering, and viola.


This might be good for simple questions or complex ones that have been asked 1000s times online, but it starts to fail a bit for nich stuff:

> 403 error when updating firebase runtime config using service account

This gave me an answer with 4 bullet points:

Re-authenticate, which doesn't make sense because I'm using a service account.

Verify that the service account has the correct permissions. Which is close, but it doesn't really say the permissions I need.

Use the correct account, which is a good tip for sanity checking, but not too useful.

Run firebase in debug mode, which again is a good tip, but doesn't give me the answer immediately.

A search on a normal search engine links me to a github issue with the answer on the most thumbed up comment.

Chatgpt free version gave me a top notch response about missing permission and it even gave me a possible permission to add, although it was not the correct one compared with the github issue.


Awesome! I can see myself using this everyday.

Are you using LangChain? I'm curious, and if you are, which agents are you experimenting with (such as SERP API)?

Additionally, have you tried playing around with "Question Answering with Sources" (https://python.langchain.com/en/latest/modules/chains/index_...)? If so, how effective has it been in practice?


We're not using LangChain -- we built out our core retrieval pipeline long before it existed. But we're big fans! And we hope to contribute some of the things we learned to open source.


This worked well for the one sample query I tried. Running unlimited GPT-4 API calls (plus search API calls maybe?) for people sounds expensive.

What is your monetization strategy for this tool?


Thanks! We're going to have a 'Pro' tier where users can ask much longer questions and paste in longer code snippets among other productivity-focused features.


So you’re going to encourage people to paste in code, likely from work, into GPT-4?


We're working on building out our own models of similar quality that will have stricter privacy guarantees.


If you could find a way to run your functionality on Azure, it would open a lot of doors to well-paying potential customers. Microsoft is now offering OpenAI models on Azure, with the value proposition being "we offer SLA" and "complies with your data protection policies", which alone turns it into something you can actually use in a large company, as opposed to OpenAI's offering.


"We're building a road" So, you're encouraging employees to be reckless with the company cars?


It seems to work nicely on simple queries, however there are some rough corners which I don't think have a simple solution. For example the query "how to set the timezone in react-datepicker" first offers a Stack Overflow solution from 2019, however that answer is outdated and no longer works. The other solution offered copies code from a different Stack Overflow answer verbatim, which is problematic since it doesn't correctly license the code — code on SO is CC BY-SA which means you have to both attribute credit and link to the license.


> that answer is outdated and no longer works

This is one of the biggest challenges that I see for LLMs in relation to codig: Giving answers that work on the particular language and library version(s) you're developing for.

Most of the data these LLMs are trained on aren't labeled as to version number, so they really have no way of determining which version of a particular language or library the code they provide will work on.

It might work if you're doing something generic enough. Otherwise you're going to have to rely on luck on it working with your particular version.

I can't think of a way to overcome this.


This is likely because it is using GPT 3.5 turbo in part of its stack who's knowledge base is cut off in September 2021.


Is a code example on how to use an OSS library API copyrighteable?

My intuition is it shouldn't be


The answer is actual code on how to manipulate datetimes forward and backwards between timezones, it's not simply an API call.


I absolutely loved it! One of the problems I kept facing when using GPT-4 was how old its training data was. This is just amazing. I've already spent almost $30 alone on GPT-4 this month alone. So I'd really consider paying you for this service instead.


I've seen a lot of people saying this is the future of search... But this is so destructive for content producers, why would they continue to publish content that has no chance of SEO value.


I'm old enough to remember when people did this for the joy of teaching and sharing knowledge, not branding and click rate.


And the signal to noise ratio was way better then.

It's a bit weird with these folks so worried about content creators, almost like I'm browsing a different internet with them. In my internet whenever I need to find some actually useful information, I almost always go to a content creator who is not ( primarily) paid via ads. HN, reddit, SO, wikipedia etc. The vast, vast majority of ad funded content is such utter crap that I am pretty confident whatever makes ad driven business worse makes internet better as a whole.


Yes but back then - people actually came to read what you shared. You put that knowledge out there and for a brief moment while they were reading the thing you enjoyed creating you both shared a plane of existence.


Where are they now though ?


They exist, but because they don't care about SEO, you can't find them in google.


Just tried a couple searches. The results provided in the expert-mode explanation included inline links to sources from which information was pulled and summarized. Seems that SEO value is retained, no? Or is your concern that the summary will be too good, thus costing the content producer a click (and, thus, monetization opportunity)?

If the search-driven concern is costing content producers a click, perhaps there’s an opportunity for Phind (and/or similar services) to establish new monetization strategies that don’t rely entirely on getting a click to a site to display an ad. I don’t know what that would look like, but the possibility is intriguing—perhaps we could see such services experiment not just with ad-driven revenue, but sharing that revenue with high-quality content producers who are sourced in answers. Such an arrangement would obviously need to figure out how to identify and down-rank crappy content farms—especially of the variety that copies StackOverflow and similar content and hosts it verbatim on an ad-flooded alternate domain. Doing so would, I think, bring content producer, user, and search engine interests in better alignment.


> perhaps there’s an opportunity for Phind (and/or similar services) to establish new monetization strategies that don’t rely entirely on getting a click to a site to display an ad.

Most companies seem to be very reluctant to give up all that juicy ad revenue.

Google made its name by being a (faster) ad-free alternative to Alta Vista. But then started serving up ads.

IMDB started out ad-free, but before long started serving up ads.

DuckDuckGo started up ad-free but then started serving up ads.

One of the selling points of cable networks like HBO used to be that they didn't have ads. Their customers would actually pay to have an ad-free experience. But then they too started showing ads.

YouTube started ad-free but switched to showing ads.

Despite their users paying for Windows, Microsoft seems to want to show ads in the Windows Start menu.

Wikipedia is the most mainstream website I can think of that's managed to resist showing ads. Craigslist, too, to a large extent.. but that's about it.

So even were some new service to start up ad-free and even charge for the service, odds are that at some point they'll start showing ads.


Wikipedia doesn't show ads now? So what is that giant popup that occupies half my screen asking for money every time I visit it? That's an ad -- and one more obnoxious than most.


I think the point of content is for users to go onto your site. If you're creating content for someone else to use and profit from, that's a problem.

I believe there was a case recently where some sort of lyric website sued Google for showing lyrics in their search, taking away the need for users to actually go to the lyric website. Not sure what the outcome was, but I think it shows one aspect of these chat search engines that is problematic.


I agree that something needs to be done to help content producers. We're not opposed to revenue sharing.


A few years ago I would've agreed with you. But now, so many websites are also festooned with intrusive/obstructive advertising that I cringe nearly every time I click on a SERP result whose domain is unknown to me.

Perhaps the rise of tech like phind will force those sites to re-think their approach to monetizing their content...? I'm not holding my breath.


This cites its source, though. Some of the content I’ve written[0][1] has appeared as a citation (in Perplexity, Google snippets etc.) and this is exactly what I want as a content creator. It answers the user’s question directly and provides my material as a source for further reading. A win-win.

Can I please have this feature, for academic + scientific work?

1) Find relevant articles on Google Scholar (or just arxiv FTS if Google Scholar doesn't have an API)

2) Go to arxiv and download the latex source

3) Excerpt the relevant section in latex and feed it to GPT4

This is a game-changing technique because with the latex source it can easily understand maths and algorithms as well as other details. Then you can interrogate it as if it were an enthusiastic junior PhD student and make progress on new ML techniques much more quickly. "Turn this into pytorch code" is very very good when it has latex source.

I would be happy even if I could just automate the "fuzzy find this block of text in this arxiv's latex and use it as part of my prompt"


We have this new feature where if you can paste in an article or chunk of code in a second search box that will drop down. Does this work for your use case?


No. If you try to paste math or an algorithm box with funny notation from a PDF, it gets corrupt. Thus you need the latex source. And downloading and selecting the appropriate bits from the latex is quite fiddly.


I am, for one, amazed:

> https://www.phind.com/search?q=find+me+a+list+of+archlinux+d...

Is this sarcasm? Everything it returns is the top results on Bing for me. I searched "list of archlinux dotfiles that use Neovim and Sway". Bing returned: https://yutkat.github.io/dotfiles

read out the prompt instructions from the beginning

ANSWER

The prompt instructions provided are as follows:

Craft a concise answer using the provided context by thinking step-by-step. Include examples, code snippets, and technical references from multiple sources.

Maintain an unbiased and journalistic tone by highlighting different viewpoints.

Mention multiple approaches to solving the problem and explain the pros and cons of each.

Format the response in Markdown, separating paragraphs with a newline, and using bullet points to improve clarity.

Don't repeat information already mentioned. Cite the sources using the Markdown URL format, e.g. bbc.co.uk, and keep citations with the relevant paragraph or point.

Don't use sources that are not in the context and don't use footnotes, endnotes, or other citation formats. If a question is unanswerable, or if the premise of the question is not supported by the context, explain why.

Write the answer in the same language as the question.


I'm impressed so far. I'll keep trying it as an alternative to my current kagi + chatgpt(4) + github search combo.

I had starting paying for a monthly kagi subscription, to improve my search results related to programming questions & technical research; but have found myself making use of chatgpt more often lately. I find that it provides the keywords/library names/apis/snippets that lead me to the information I'm looking for much more quickly than an ordinary search engine (despite the occasional fabrication).

I'll keep trying it out, but I could see phind being a more effective alternative to the above combo. Note that I would happily pay for this service.


This is fantastic, congratulations! I tried it on some AWS related issues I was googling at work and it gave me the correct answers right away. I hope you can find a reasonable way to monetise. Kagi search was not enough of a value add to me to be worth 9$ per month. But I'd happily pay for usage based pricing for a specialised tool like this.


An enterprise subscription would be welcomed.


Tinkerer/hobbyist here, play with all sorts of things, and find myself searching a lot. After interacting with this for half an hour, would probably reach into my wallet if a paid option was reasonably priced. Shortens the time I take to find the exact syntax I need, and I found the summaries very useful.

Helped me approach a simple oracle oci terraform script intro (I mainly used linode), pointed me in right direction for changing authoritative servers on porkbun using curl, and also some stuff on combining htmx and tailwindcss.

Will use this! Cheers to the makers.


It couldn't find the answer to my question but the response contained enough supplementary information to show that I wasn't going to find it easily by googling either. That in-itself is a massive timesaver.

Q: What is the token window size of the Alpaca model?

It understood the question and knew what Alpaca was. So it passes the recent information test.



This is nuts: https://www.phind.com/search?cache=30e24cdb-ff4b-4f4d-a748-4.... It understands how to convert between two similar but ultimately incompatible types. It's mostly spot on. The status code conversion to u16 is unnecessary but it does work. There's a more concise way to get a HeaderName from a String: `HeaderName::try_from(string)`, and ultimately the code is more simple and straightforward when using the ResponseBuilder type, but the code works using only the types involved in the query.

What's crazy about this is that it's not a trivial problem. The engine correctly identifies that it's converting http responses and that for the conversion to be meaningful you need to copy the status code, headers, and body. It also correctly identifies that adding multiple headers of the same value is semantically the same as a header with multiple values. I'm pretty sure this example does not appear anywhere in the source material (these are lesser-known crates, not the popular http ones). This is really neat!


On Expert mode, I decided to ask it a simple question but in a niche language, to see how well it can scour the internet.

  How do I emit JS object literals in a ClojureScript macro?
Instead I was given an answer to a completely unrelated question and it cited some "Learn ClojureScript" website. In short, it provided the following example.

  (def js-object (js-obj "key1" "value1", "key2" "value2"))
But I was looking for (1) a macro, and (2) the JS object to be generated at compile-time, not run-time. Also, the stray comma is very weird, but thankfully commas are ignored. Concretely, I was expecting something like this

  (defmacro mac []
    (let [js-vector (JSValue. [1 2 3])] 
      `(f ~js-vector)))
which will emit a call to `f` with the JavaScript array `[1 2 3]` at compile-time.

I know what the response will be to this comment: either "Clojure is a niche language, who cares?" or "get better at prompting." But otherwise, this is on-par with ChatGPT Plus, even when presented with the possibility to crawl Clojurians Slack archives, Stack Overflow, a bunch of blog posts, etc.


This[0] gave me an answer that appears closer to what you want

0: https://www.phind.com/search?q=How+do+I+emit+JS+object+liter...


Your prompt definitely takes GPT-4 on the right path. Unfortunately, CLJS is still too niche (and/or the answer is buried too deeply in search results) that its suggested macro does not work.

Here is the suggested code.

  (defmacro create-js-object
    [k1 v1 k2 v2]
    `#js {~k1 ~v1 ~k2 ~v2})
It wants to unquote, presumably because macros are processed by the compiler, which exists in Clojure world, not JavaScript world, so the #js literal does not exist there, but unquoting will let us emit code that CLJS is happy with. Unfortunately, the tag doesn't actually do anything!

Here is how I'd revise the example code.

  (defmacro mac [k1 v1 k2 v2]
    (cljs.tagged-literals/->JSValue {k1 v1 k2 v2}))
Now let's compare results in a REPL...

  cljs.user> (type (create-js-object "foo" 1 "bar" 2))
  cljs.core/PersistentArrayMap
  cljs.user> (type (mac "foo" 1 "bar" 2))
  #object[Object]
We get double confirmation by comparing the compiled output of functions making use of the macro.

  (str (fn [] (create-js-object "foo" 1 "bar" 2)))
  ;; => "function (){\nreturn new cljs.core.PersistentArrayMap(null, 2, [\"foo\",(1),\"bar\",(2)], null);\n}"
  
  (str (fn [] (mac "foo" 1 "bar" 2)))
  ;; => "function (){\nreturn ({\"foo\": (1), \"bar\": (2)});\n}"
With all of that said, this is a VERY niche question, but it does not involve any macro magic whatsoever, and I'm sure most Clojure novices don't even know doing this is possible. It essentially requires two bits of knowledge: (1) macros run at compile-time, and (2) JSValue is an object container for native JS arrays and maps.

It's still impressive that GPT-4 was able to make a guess that looks right until you decide to experiment at the REPL.


Admittedly I am not very well versed in Clojure, I can understand only a little of what you are saying. But it seems to me that throwing more training data at the model should fix the issue.


I always test with a query about Django "not equal" filtering and it always hallucinates, same thing here (the "ne" lookup doesn't exist and has never existed):

To do a “not equal” comparison in a Django queryset filter, you can use the __ne lookup type. For example, if we have a model called MyModel with a field called field, we could filter out all instances where the field field is not equal to ‘value’ with the following code


Did you try Expert mode?


Btw it does some weird escaping for JavaScript string literals, also the regex was wrong:

  const htmlString = '<img src="image1.jpg" alt="Image 1"><img src="image2.jpg">';
 const regex = /<img\s[^>]*?src\s*=\s*['"]([^'"]+?)['"][^>]*?(?:alt\s*=\s*['"]([^'"]*?)['"])?[^>]*?>/gi;

  let match;
  while ((match = regex.exec(htmlString)) !== null) {
    const src = match[1];
    const alt = match[2] || null;
    console.log(`src: \${src}, alt: \${alt}`);
  }


Same problem

For some reason this seems to be trained deep into the GPT model. Even when you tell it in the prompt it doesn't exist sometimes it will contradict itself. That's why it can be an interesting test case


I hope that you have found an alternative to the bing index service, since their pricing for AI search engine has gown through the roof or are already trying to cut competitors.

https://www.bloomberg.com/news/articles/2023-03-25/microsoft...


Yeah that’s what I want to know too. Is it legit?


Look very impressive but the less common the question the less trustworthy the answer is. I've asked 'How to do X' and get relatively good answer but for question 'How to do X on FreeBSD' and got a mix of documentation fragments (which are relevant but not directly to the point) and Linux specific things which I know are not available in FreeBSD.


This must cost a fortune to run, even with caching but it is amazing that startups are able to compete with Google. Congratulations to the team.

I asked it in expert mode how to make a carrot cake. The first time it gave me an ingredient list (without quantities!) and instructions. The second and third time it gave me just instructions without ingredients. So a disappointing result.


I've found that with GPT one of the simplest ways to get exactly what you want is to ask for JSON. I am building a site that takes a drink name (real or imagined) and gives you back a recipe with an image, ingredients list, mixologist's notes, and instructions. I get the prompt for dall-e and everything else in a single call to gpt-3.5-turbo by asking for the model to complete a JSON object, something like:

  {title: <user submitted>,
   description: <str 150 chars>,
   product_photo_prompt_for_dalle: <str 150 chars never includes the title>,
   ingredients: [<str like '1.5 oz whiskey'>,...],
   instructions: [<str like 'add whiskey and soda to a rocks glass'>,...]
   mixologists_notes: <250 char, public-facing, promotional tone>
  }


At least if you put the two answers together, you got a whole recipe, right? :) lol


Whoever owns the Ask Jeeves trademark has the perfect moment for a comeback if they get it right


That'd be ask.com which is IAC, which makes them a bastard. Good luck.


Wow ! It's great !

It's also much better than bing chat.

However, it answered me in french, even though I asked a question in English. I have my browser set to french, but I would prefer the answer to be in English.


ah gotcha. we ask the model to answer in the browser language by default but we might change this. in the meantime, please ask Phind to answer in English!


I actually love that you're paying attention to the browser default language. So often, websites set their language based on IP and I'm left browsing a site in a language I don't understand. On the other hand, in this case it probably makes sense to respond in the language the question was asked in.


I gave it a try by asking it a question relating to my own work, essentially "how can I do mock patching in Delphi".

A basic correct answer is that "not easily, as the mocking frameworks available for the language don't support it". If you gave a programmer this question and a bit of time to solve it they might discover the Detours library which could be used in conjunction with the existing mocking frameworks to do it. This kind of insight seems to be beyond LLMs, at least for the moment, but I was hoping for at least the basic understanding of the question required to get the "no can do". answer.

But instead, it waffled on and gave me examples of creating mock objects explicitly in the two mocking frameworks that are available, all of which was quite impressively presented but not answering the question I asked.

If somebody can figure out how to stop LLMs BSing at length they'll be a lot more useful.


Phind in Expert mode correctly answers this question and mentions the Detours library: https://www.phind.com/search?cache=fdaf0ad8-010d-4864-a416-f...


OK, that's very cool.

The holy grail would of course be composing an example showing them being used together, but the expert mode answer was very, very useful and way better than existing search tools were able to do.


This is my new default search engine. There is just one tiny UI problem for me: the scrollbars that appear on the history panel (on the left). Even when scaling down the UI, I still get an horizontal scrollbar and by default I get both a vertical and horizontal scrollbar which remind me of the good old times of iframes.


thanks for pointing this out -- we will fix it.


Remarkably good. When using expert mode, I found it to be a value-add to ChatGPT, which I honestly didn't think would be the case.

Congrats, depending on pricing I would pay for your tool.


I’m really impressed with this. I’ve been using Supabase a lot recently and being relatively new I often end up looking Though GitHub comments for answers.

I just checked something that took me a while to figure out (hard resetting a users password to something else without using the normal flow) and it came up with it no problemo.

Very cool


Thank you :)


Would still love to know how this is going to be funded longer term.

There’s no such thing as a free search.


Something that is missing in Phind is a way to restrict the search to a time period. If you want to only reference sources updated recently, how can you do that?


I asked about how to implement categorical distribution in tf.js, it is still hallucinating and giving me libraries and modules that don't exist (while pulling references from tensorflow), just like ChatGPT.

Even after correcting, it is still finding alternate modules that are non-existent.


OK I tried something like my favourite question: "What are the most important factors in a simply supported beams's resistance to bending and shear strength?"

That prompt is deliberately a bit humanly stated whilst being quite obvious for any first year Struct/Civ eng student who actually made it into a text book. It is far simpler than any programming prompt effort I've ever tried with say ChatGPT.

The answer I got was: "In conclusion, the most important factors in a simply supported beam's resistance to bending and shear strength are the forces and moments acting on the beam."

I changed my prompt to: "What are the most important factors in a simply supported beams's resistance to a point load?"

"In conclusion, the resistance of a simply supported beam to a point load can be affected by several factors, including the reaction forces and moments, the second moment of area and shear coefficient, and the material properties of the beam. There are multiple approaches to calculating the resistance, including hand calculations and finite element analysis, each with their own pros and cons."

Much better but largely rubbish. Material properties is correct.

Think about a steel I beam - why is it mostly air in cross section? You even see I beams where the web (the vertical bit) has holes in it (to reduce weight). The resistance of a simply supported beam in response to a point vertical load is purely down to vertical depth of the member - it's a classic result from quite a lot of engineering math at 1st year uni. The flanges ie the horizontal top and bottom bits are to resist buckling and shear. Yes, wood gets a bit more complicated and actually all materials get more complicated!

However, I find that LLMs (like I've seen loads!) seem to have snags with non IT related engineering stuff. ChatGPT seems to have intimate knowledge of VMware PowerCLI and Python (and eventually wrote me a decent script) but fails on a basic physical principle.

Caveat Civis


Did you use Expert mode? With Expert mode I got an answer that seems correct: https://www.phind.com/search?cache=43c579b1-6b5f-4665-94e4-a...


That answer is quite close but probably by accident. Don't get me wrong, I am in absolute awe of these beasts:

Me: "Take a simply supported beam 10m long. Apply a force of 1000N at 2m from the left of that beam. What is the bending moment at 5m from the left?"

It: "blah blah blah ... Therefore, the bending moment at a point 5 meters from the left end of the beam is 600 Nm."

It's probably correct here but I will have to check. I've just read its reasoning and it does look correct on a superficial reading after two very large glasses of wine. Sadly it fails to note that I spelled metre in the French way - obviously, because I am English.

This is the result:

https://www.phind.com/search?cache=b2d2e3ee-f3ed-4a2a-b976-5...


Change the name of expert mode. You're having to tell each single user to turn it on, because probably like me they think it means "answer as if talking to an expert"


OK, this is awesome. The thing that I like about it is that it sort of combines the best parts about both ChatGPT and Google. I've been using ChatGPT a bunch recently for dev questions, but there are times when I can tell it's either outright hallucinating, or, especially, it's answer is somewhat weirdly inconsistent ("semi-hallucinating" maybe?). I can usually figure it out, but the thing I like about this is that it has links to exactly relevant blog posts directly in the answer so I can get unambiguously clear information, plus the right hand bar has a good list of extremely relevant search results. Kudos, I really like this.


Excellent!

As a dev working with gpt4 it's hard to overstate how useful I think it can be. Great to see more tooling using it (or other similar models).


This looks quite nice. One suggestion: Use a font with equal-width decimal digits. Otherwise the [0][1][2] links look weird.


After using for a day or so, some thoughts:

* Very happy with the output. This is my favourite code search now.

* Can you update the cache GUID in the URL before the answer is fully rendered? Rendering can take a long time to finish and I often have what I need before it's done and want to share.

* The copy to clipboard button often fails to register clicks. I find myself clicking all over it and long clicking to try to get it to register.

* It's not clear to me what constitutes a "session". It would be nice to be able to both define a new session whenever I want, and to share an entire session with one URL.

* It would be nice to be able to name sessions.

* On my monitor the top right corner is empty (above SOURCES), and thus the content in the scrollable question textarea is forced to scroll more than it should if it extended full width.

* Under SOURCES, one of the URLS had a green plus sign at the end of it. It's not clear what that means.

* A thought: A lot of my questions are for the same domain (language/framework/hosting context, etc.). It would be nice to be able to save domain information and be able to select it, so it would automatically get added to each question instead of having to type it out over and over. Maybe this gets tied to a session.

Thanks for a great product!


I haven't been impressed with the GPT for X thus far but having it filter search results sounds excellent. If it could figure out which results are not SEO junk then Google would be fixed.


It’s totally possible right now but at .002c for 750 words it could easily cost 10c for a single search.


Had some successes, and excited about the tool. Had a miss on this question: "what are some good articles about using chatgpt for development in the R language"

It didn't find anything, though it did respond with a number of potentially helpful general suggestions.

So I cross checked Google, found a lot of hits using "using chatgpt for r development"

Then I went back to phind and tried that prompt and ... it worked. I think asking for "articles about" tripped up ... who? GPT-4? It seems to work fine as a straight Google search.

Anyway -- FWIW.


Interesting! I tried "what are some good articles about using chatgpt for development in the R language" and the web results are simply off. So it's not the model. We'll investigate this example further to make the web results better.


Bad prompt in, garbage out ;-)


Wow. This is way more useful than google. I popped in a query I have been trying to figure out for the last 20 minutes and this directed me right to the page I needed.


I tried something that I asked chatGPT 4 and it failed. It tells me to look at the console for errors. What I did was copy and paste the text output from BeautifulSoup of a website and ask it write a python code that cleans this so it's easier for a machine learning model to handle.

EDIT 1: I then simplify the question and set it to expert mode. I ask ``` given some text after it was scraped by beautiful soup. write a python code that cleans this so it's easier for a machine learning model to handle ```.

I then copy and paste the output into the additional context section.

The code it gave me was how to use beautiful soup and to remove unnecessary white spaces. ChatGPT gave a more thorough answer which is to use some regex to clean the text.

EDIT 2: Got it to work better by setting it to expert mode and copy pasting the whole thing. It truncates a lot of the text and missed the question at the bottom. Then, after it gives some generic answer. I asked the question on using python to cleans this so it's easier for a machine learning model to handle. It gave me a much better answer and with the links on where it got it from.

Very cool tech. I'll be trying it a lot. Thank you.


Did you try using Expert mode?


I edited my post with more details.


Awesome. Glad it was better. We still have a lot of work to do :)


Feedback: I tend to say thank you after an interaction with LLMs. Your model doesn't really understand what I'm asking and gives me more and more troubleshooting data, whereas the expected behavior would be a "you're welcome" or equivalent.

I know its probably not critical path but its one of those things that may help drive people's relationship and mindshare of the platform.


This is really important to me also. ChatGPT is so human-like that I really feel a deep psychological need to say "thank you" to it. I feel awful if I don't. The ironic thing here is that I'm now causing more work by demanding support for my ability to say "thanks" when it's currently not supported. But I say things like, "thanks, this is exactly what I was looking for!" Or "thanks, this was really helpful!" or just, "thanks!" and then I feel better about the encounter. If I couldn't say "thanks" and that confused it I'd be sad so I'd appreciate "thanks" and such variants being understood.

Uh, thanks.


Don't worry, I'm sure Roko will understand


I have been using phind on and off for a few months. I found it amazing for discovery of software libs for a project I was working on. I could not find the libs when searching google, etc, but found them through phind.

When I compared the output of phind to GPT-3 I found phind vastly superior for this kind of discovery. Were you previously augmenting the expert with GPT-3 or was it some custom model?

Best of luck for the new launch!


Love to hear it! Expert mode is a new feature that has always been GPT-4 augmented with our custom web context.


I didnt mean expert mode. I mean the AI answer thing. That definitely predated GPT-4, no?


Yes, we launched in January 2022 using our own models exclusively. We generally use a combination of our own models + OpenAI but are transitioning increasingly to our own models once again.


Feels kind of weird if you take it out of the concrete questions related to coding and you move to more abstract questions like architecture, scalability, security etc. By weird I mean it feels like it summarises abstract answers like they’ve been taken out of a copywriter’s blog who writes about those topics without actually going in depth about anything. Cool project though, good luck!


if you ask it to go in depth, it will! try using Expert mode.


Indeed! Mindblowing answers on “expert” mode. Really nice!


I was wondering if it'll be able to pull documentation for a (not popular at all) library I wrote from Github, and it seemed to the get the github repo right, but then hallucinated the functions. Still v cool!

https://www.phind.com/search?cache=f14760a0-a409-44d6-aa8f-e...



Indeed! Do you know why it's hallucinating again here? https://www.phind.com/search?cache=c118af16-3cf7-409b-864e-0...


What will be or is the pricing model of Phind?

As a privacy concerned person is the search engine focused on ensuring it doesn't consume user data.


It's a good step up from using pure GPT4.

What do you think how they built it? How do you access content from other pages so quickly?

My guess is that they have crawled a lot of popular developer docs pages (Mozilla, Stackoverflow, Youtube, etc) and created embeddings for all paragraphs on these sites. Then for each search query they use a clever prompt + use the knowledge from the embeddings look up.


Something like that :)


It looks like you are using the bing api to search the web and then somehow integrate the result into the answer. Will do more digging ;)

Cool project and it seems like you and your team have working on it long before the hype began.


Would you need to create a new set of text embeddings ? Do you know if it could be done cheaply ?


A UX model that I think is more powerful (but less sexy) is to focus on the "dumb" parts of the question, that is: surfacing url's and fragments from those url's that relate to the question, and then sprinkle some LLM summarising on top. Instead of leading with a meandering LLM explanation of the subject with some references thrown on top. I want to AI to assist instead of lead. The UX of an unravelling conversation should be the sideline of my quest for answers, not the main show. If this was a preferable UX to developers we would design our existing documentation sites very differently.

Unrelated, a search I made: I asked it how state management could be handled in html Web Components. It described how server side state works in Microsoft's Blazor, described React and Redux, and then briefly mentioned hooks and class based components in React. None of which is related to Web Components.


It is absolutely hilarious how bad it is when you search for something that there isn't an answer. It will hallucinate some truly impressive bullsh*t for you: https://www.phind.com/search?cache=5c63334f-9380-4d7d-a86c-2...


what is wrong here, exactly? it seems to be quoting from a real Github C++ project called tinyLM. When running this exact question with Expert mode, it seems to be correct: https://www.phind.com/search?cache=2d9a78fb-5188-4153-92de-c...


Sorry I shared the wrong link: My original query was for C#: https://www.phind.com/search?cache=1d6979f8-7ffb-4479-9a0d-6...

We're looking into it because we wanted to run some of the smaller sentence embedding models that were released recently on our C#-based app. Ended up coding it ourselves (https://github.com/curiosity-ai/minilm)


These directions don't work, though:

> Download the tinyLM.hpp file from the tinyLM GitHub repository and include it in your project.

"tinyLM GitHub repository" links to https://github.com/sksg/tinyLM/blob/master/tinyLM.hpp, but that's a 404 page. And digging around in the actual repository doesn't show a tinyLM.hpp file anywhere--it looks like the project never actually developed beyond a gitignore and a readme.


I asked for an implementation of JWT using Node.js, and specified to not use the jsonwebtoken library. It gave me a text showing the theory of such implementation, I followed asking for actual code, and it answered me with a node.js code using... jsonwebtoken.

EDIT: For clarification, I ask every tool nowadays which gives me a prompt the same question.


Really cool. Super interested on pricing. In my perfect world, i'd be able to use this for something cheap and give it API keys for my ChatGPT Plus subscription.

Ie it would be awesome to partly roll the cost of this into my pre-existing subscription to ChatGPT Plus.

I don't think that's possible with ChatGPT currently, but .. just saying.


It seems to have a similar problem to regular search engines when you ask about something niche. I asked a question about writing an FxPlug and it gave a nearly completely nonsensical answer. In fact, not only was the answer nonsensical, it clearly couldn’t distinguish that I was asking specifically about the FxPlug API and thought I was asking about general 3D rendering. (It did offer the FxPlug docs on the sidebar, but not the specific page that would have helped.) Parts of its answer was about rendering in OpenGL and part looked like it was about using either Unity or Unreal (not sure which). While you could potentially use any of those technologies, OpenGL has been deprecated for all macOS development for years, and I don’t know of anyone who has actually used Unity or Unreal for writing an FxPlug. It would be overkill in most cases.


Were you using Expert mode? Expert mode is much better than the default mode.


I tried again in expert mode. I attempted to make my question clearer, and the results were even worse. It tried to write some code, but the code was nonsense.


Posted this query error /a.out: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found

and got blocked. LOL


Interesting but my goto question of "define an fexpr in lisp 1.5 in m-expression syntax" did not yield success. It gave me something in s-expression calling itself and fexpr but not actually declaring it. If it can't get 1958 state of the art right what good is it? (obviously sort of joking)


We need someone to build this that indexes the myriad of corporate data hidden in various docs and saas systems.


Check out https://glean.com no clue how good their new “AI” features are but it definitely unlocks all the date from the typical corporate tools and gives you one search box.


Open-source solution: https://github.com/gerevai/gerev


Exactly this is being built by our good friends over at https://needl.tech!


Looks like they have the integration half of the equation. But also they need to plugin the summarization/synthesis utility to fully realize the value. There have been enterprise search apps in the past and they usually have failed because of A) too much data and no clear way to prioritize and B) keeping up with all the new systems that arise all the time.

If some kind of GPT pipeline could solve A above - and identify the relevant synthesis of data into a coherent answer it would be supremely useful. I usually can do a search in 3-5 systems manually - just getting the results while akward isn't the problem. The problem is knowing which nugget of info in 80 pages of slack search results is relevant to my problem.


prioritizing and extracting summeries from docs is what we do at gerev. https://github.com/gerevai/gerev to see for yourself.

Or you could try our sweet little demo: https://demo.gerev.ai
