“We are releasing a model every week after pacing the frontier.” Seriously!
Pace of OpenAI model releases: GPT-5.4 - Mar 5 GPT-5.5 - Apr 23 GPT-5.6 - Jul 9 GPT-Astra - Sep 3 Frontier labs are asked to “Pace the Frontier” - Sept 12 GPT-6 Sol - Sep 22 GPT-6.1 Sol - Sep 29 We are releasing a model every week after pacing the frontier.

Years into the LLM era, one thing hasn't changed: the model sets the floor, you set the ceiling. AI makes mediocre work cheap. It doesn't make great work common. Taste, judgment, and depth are still what separate the two.

the right way to use model capabilities is not to ship 10x more features to prod it's to spend more time understanding your users, trying experiments, building prototypes, learning about things you don't understand so that you can ship things that actually work

especially for consumer founders, i don’t think it’s very effective to shill what you make on X in most cases. better to shamelessly promote what you built in insta/tiktok. then shamelessly flex your wins on X.

Own your agent Own your harness Own your intelligence Build on open source Build model agnostic Build on Mastra
We’re ending our partnership with Cursor following its acquisition by SpaceX. Under our proposal, Cursor’s direct access to our models would end on November 12. We know that the people most affected by this decision are the developers who rely on OpenAI models in Cursor. We care about their experience in this transition and we’re ready to go above and beyond to support them. openai.com/index/our-decisio…

to be fair, if someone trained me on the entire internet, i don't think my ego would let me say "i don't know" either

AI models: 94% cost reductions compared to models released... in the last month.... trying to keep up. 🤯😅
GPT‑5.6 Luna xhigh is near Opus 5 performance being 17x cheaper🤯 The new Browser Use pareto frontier is wild👀 Luna was already good. Now it’s almost unfair.

Your harness matters a lot actually
Turns out GPT-5.6 Sol is actually SoTA on ARC-AGI-3. Just took two setting changes. You just have to allow it to reason and work over multiple context windows with the help of our canonical compaction implementation. openai.com/index/how-two-set…

I gained 30 pounds in building my previous company. And let’s just say, it wasn’t muscle. So this time around, I decided to do it different. Not gonna turn this into a food blog. But will post some pics along the way. Let’s call it my Cooking for Founders series Let’s go win this thing. 😊✌️

Frontier labs: models are the moat Custom model companies: custom models are the moat Router companies: model routing is the moat Data companies: data is the moat Application companies: applications are the moat

Turns out that having a talking “company brain” is not so easy 😅
we installed claude tag and now someone on the team needs to tell it to shut up every 30 minutes
