The big takeaway is they announced decision model API for Luna

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.

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.

i'm just glad i can use my Dootle Dots™ without context switching.

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).

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.

Why do those videos look like something out of Black Mirror?

None of this matters. The real news is the upcoming changes to the subscriptions. OpenAI just rugpulled $200 plan users by slashing their usage in half and releasing a new $500 plan with the old usage plus a little more. Amazing, isn't it? Half the usage for the same price, or slightly more usage for 250% of the price! Are you not entertained?!

Lots of good stuff flying under the radar. - Subscription sharing is going to be huge for indie apps that don’t want to deal with token billing. - Security scans built-in to Codex seems useful. - Decisions API is a validation for Jev and the entire space it created.

I love the fact that they're advertising the latest Codex Cli while most Windows users had to rollback/downgrade to an older version because of the annoying excessive terminal screen flashing issue ( https://github.com/openai/codex/issues/48074 ) (I see a newer version was posted an hour ago. Let's see if the issue is now fixed...)
