LLMs are like the wild west. Things are moving fast and no one is really documenting things for outsiders. The only way to learn these things is by using them. If you tried out Oobabooga, you would know that each LLM needs their own template instructions to understand its input and respond correctly. More recent tools, like Ollama, have these instructions included with the models. However, there are still different types of models available through Ollama. Some of them are suffixed with "instruct" which tells you that you can use them like a chat bot, whereas other "main" models only do completions and spit out gibberish if you ask them a question.
If you click on the top right "Try Perplexity", it brings you to the main page where it shows more information. On that page, (bottom right) theres a ? button where you can find help articles that tell more about what it is.
There's at least one more step for me at least. I had to close a pop up panel about "Sign in or create an account". There was no indication that anything was behind it. If the were trying to hide the true nature of this thing, they'd be doing a great job.
