Dev Day announcement overview, as short as reasonably possible.

- Dots: personal assistant (similar to GrokBot, Muse etc)
- $500/month plan including Ultrafast
- GPT-6.1 Sol: really smart and cheap, way better than 6 was
- Decisions API: Jev killer with vision capabilities
- ultrafast is real (300tps on Astra). It’s way expensive though.
- sign in with ChatGPT: use your sub and inference in 3rd party apps
- extensions in ChatGPT can now be full apps
- 1 banked reset for all

I think that’s most of it!
