How did that work for the Facebook phone? And all their billions of fervent Facebook users?
Google own this space - pixel phones already do pretty much all of this, and they have the best models and the most users too. No built in agentic capabilities yet, but I am sure that is just a month or two away (see project mariner).
If you've not tried the pixel photo ai features already, you may be surprised. Things like changing lighting, removing people from the shot, auto-stitching people into a group photo, composites group photos so you get one photo where everyone is smiling and looking at the camera at the same time even if that never happened etc, text-editing photos etc. Gemini live is like a facetime call without the 3d avatar but we've seen they can do it with Veo3 already if they wanted.
This is all reality today already in the hands of billions of Google users, so OpenAI have a bit of a hill to climb: OpenAI would need to not only catch up with Google (both in AI space which they seem incapable of doing right now but also in product too) and surpass them.
Google are totally integrated in this space - the device, the software, the AI models, the infrastructure, the data, the sites/apps people use (search, Gmail, maps, YouTube, docs, ...) and also the billions of users.
I doubt OpenAI can really make a dent here. I suspect any OpenAI-Phone will be quietly discontinued like the Facebook phone
