Yes, they would be, because you are still logged into your Apple account. You wouldn't use iPhone Handoff for border crossing unless you wanted to leave one phone at home and transfer your number to the iPhone you are taking with you when you leave the country. Still, the phones would have identical data on them unless you turned off syncing for certain apps, such as iMessage (messages).
So you can use more than one iPhone as your primary phone. For example, if you have the new iPhone Duo but want to use your other 'standard' iPhone for the telephoto zoom camera capability, you could transfer your phone number from the Duo to that phone for the day if you're going to be out taking a lot of pictures. When you are done, transfer it back to the Duo, and the Duo will become your primary phone again.
Honestly, a carrier charge for this feature doesn't sound any less reasonable than a variety of other near-zero marginal cost services providers have offered in the past, but $5 seems steep since you can add an entirely separate user to an existing family plan for not much more than $10.
The SMS forwarding is handled entirely within iMessage.
Phone call forwarding works when all the devices are nearby, and they can handoff the audio streams between themselves; but you can't pick up a phone call on your Mac if your phone is on the other side of the world/at the office/etc; the feature we're talking about here would not have this limitation.
I think for phone calls this only works on Facetime and for calls maybe only on Wifi.
SMS syncing is true. But if you have a phone and you're out and about you also need mobile data, so would otherwise need a second mobile plan. Or to swap the SIM over, which was easier with a physical SIM, more difficult with eSIMs.

Ah, so the functionality that switching the physical SIM card gave you instantly and at no cost at all.
I've been using Opus 5 for coding a lot lately, and compared to Codex (which I never had trouble understanding), this issue is driving me up the wall.
So much so that every time Opus 5 finishes a plan and shows me the summary, I have to prompt it again to explain everything it did in an “ELI5” way so I can understand what the heck it is saying.
For example, Opus 5 told me in a summary that “Net legs ran small rosters, not the plan's full ones”. When I asked for the ELI5 of what that meant, it said the client dropped video frames during testing and got 30 FPS instead of the required minimum of 60 FPS.
Sadly, I don't think so. I remember Leo saying some not-so-nice things about John on the pre-show to TWIT a few months ago. I never understood how Leo couldn't forgive John for whatever he did, but Leo has had long-lasting feuds with a lot of people over the years. All that wasted time fighting between those two when we could have had them doing great shows together over the past few years and giving us great content. What a waste of time fighting.
Too bad him and Leo had a falling out years ago. I really loved watching those two together. I remember John was always borrowing Leo's equipment, such as camera lenses, and he would always forget to bring them back and Leo would always scold him for that.
Not a blog, but a podcast, but I love "The AI Daily Brief," and I listen to it daily because it keeps me up to date on almost everything happening in the AI universe.
I'm sure this is not new thinking, but it was part of my discovery process. My objective wasn’t to crank out an app, I wanted to understand the process of using an agent to build something. I went into it thinking about how I’d work with a new employee. When I work with someone new, I explain ‘my API’ and try to understand theirs. How do I communicate, what’s my level of understanding, how can we collaborate most effectively. That’s been refined into the working_with_me.md doc.
I knew the context.md file, but read how big and cumbersome that file can get, and that as memory fills in a session, more of that context can be left behind. My project wasn’t about speed; I knew I would need a way to pass the latest session details - status, open items, decisions made in session, etc - to the next agent in a new clear session. That was the thinking behind a session state doc.
I created those two docs outside of claude.md, with session.md living in each project directory, and working_with_me.md available in the claude root directory.
My starting instructions are for the agent to read those docs - plus other project info, and my ending instructions are to update working_with_me and handoff.md. If mid-sessions something is lost - like the agent gets sycophantic, I’ll stop and dig into that, trying to understand how context was lost and how to firm up the point.
Very impressive, especially since you did it solo. The website looks great and explains everything in detail.
Can you elaborate more about its development? How much do 110B tokens equate to in $$$? What LLM did you prefer most during development? Any suggestions for other solo developers trying to launch their LLM-built product?
How are you accessing their API? Through OpenRouter, or direct? Are you using DeepSeek v4 Pro? $2 seems a lot cheaper than my own experience accessing them through OpenRouter for over 100 million tokens, but I am using OpenRouter to access v4 pro.
Cache hit rate dominates your total cost calculation for long agent session, and it largely depends on the provider. Deepseek's native deployment is probably much better than third party in this regard. For v4 pro it's a whopping >100x price difference between normal input vs. cached input tokens.
I am using Flash and accessing the API directly via vscode insiders and occasionally Zed (it's buggy but I keep coming back to it because I want it to succeed).
Unless you need enterprise multi-model management, I don't see the point in OpenRouter as it just adds cost overhead and you can just self-host an open router alternative (LiteLLM, Bifrost, etc). Running an LLM gateway locally is kind of nice as it allows you to normalize your configurations against your internal gateway - but I haven't really needed to.
Deepseek direct is atleast 2x cheaper than other providers serving it. Maybe their caching strategy is just significantly better or they’re subsidizing api pricing. I think it’s the former. $2 is closer to 50 million v4pro tokens in my experience
Ensure you're hitting the DeepSeek provider via OpenRouter - they have the massive cached tokens discount. If you're hitting any other provider you're paying an order of magnitude more.
Pro is substantially more expensive than flash. In addition, there's wide variance in price with DeepSeek themselves providing the cheapest tokens last I checked (but they train on them). Caching policy also varies by provider. TTL can be as low as 5 minutes or as high as 24 hours and reading from the cache might or might not reset the timer. Whether or not you get a hit makes (IIRC) a 10x (edit: it's actually 50x) price difference in the case of DeepSeek themselves.
