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!
