OpenAI Opens ChatGPT to Agents and 1.2 Billion Weekly Users
DevDay 2026 Recap

At DevDay 2026, OpenAI unveiled over 20 announcements, including Dots—always-on agents that take on ongoing responsibilities—and opened ChatGPT as a shared surface where developers can launch native experiences for 1.2 billion weekly users. The event also introduced GPT-6.1 Sol, Astra Ultrafast, Codex cloud environments, and an OpenAI Marketplace with 16 partners.
We believe AI can help bring about a new renaissance of creativity and discovery. It should give people more time for what matters to them, more freedom to pursue their ideas, and the ability to do things they didn't think were possible.

This could and probably is me projecting, but the enthusiasm was tepid. The Opus 5.5 mog cast a pall on the room.
The stuff that came off as potentially exciting was the ultrafast stuff available only to Pro 500 users.
The reset button stuff was an embarrassment. Everything that was released today, in respect to the hype that the team projected on twitter, was a failure. The internal OpenAI slack is a hell of an echo chamber.

No one mentioning Decisions API?
Feels huge. Sounds like Luna on their Ultrafast infra.
I did some internal benchmarking and found that GPT 6 Luna in batch mode at 20 records per batch was about 1.6x faster at 1.2x the cost of Jev with no tradeoff in accuracy. Tuning it up/down would make it faster per-record while also reducing the cost (assuming accuracy holds). Though this was only useful for offline processing.

It’s simply ridiculous. None of their 20 new features seem genuinely usable for day-to-day life; I’m struggling to find any use cases for them. I have no idea what they were thinking with "Dots". The "Super Fast" addition is nice and important, but it’s just one small bright spot in a hellscape of useless features.

Sign-in with sub accounts seems big. This is how I thought this was always supposed to be - the providers acting more like an OS/ecosystem-enabler.
Extensions into codex also seem cool.
The provider also eating the application stack at the same time, doesn't make too much sense. I don't want my team going all in on one provider versus the other. (things like the docs/slides/sites).

The big takeaway is they announced decision model API for Luna
