Cursor has been a trusted partner of Anthropic since Sonnet 3.5. We’ll continue to increase compute to support Claude models in Cursor and are excited for what comes next with them at SpaceX.— Tom Brown (@NotTomBrown) August 29, 2026
Reflections on OpenAI
I left OpenAI three weeks ago. I had joined the company back in May 2024.
It’s not just the vibes that are off inside OpenAI.
It’s the numbers, too, according to a new Wall Street Journal report, which echoes The Information’s claim earlier this month that CFO Sarah Friar has expressed concern about its IPO plans and CEO Sam Altman’s datacenter spending. It also says the company “missed an internal goal of reaching one billion weekly active users for ChatGPT by the end of last year,” and other revenue targets.

OpenAI Model Spec
The Model Spec specifies desired behavior for the models underlying OpenAI's products (including our APIs).
OpenAI says it plans to stop supplying models to Cursor on Nov. 12 after SpaceX's acquisition. Cursor says OpenAI is about 5% of its traffic. Anthropic says it will increase Claude compute. This is not just another Musk–Altman fight. It tests whether model APIs are actually neutral infrastructure.
Nailed it, @komorama.bsky.social We have a huge opportunity here – there's no reason the future user interface for *all your computing* needs to be tied to OpenAI. We can build a new, uniquely personal computer that you own, without your entire digital life being locked to one company or provider.
