Is there a way to work around this (like using your OpenAI limits directly?)
The first party cursor models (initially composer and now grok-cursor) and price very competitively for their quality and have very generous usage limits included in the base plans, and then per token pricing afterwards.
Occasionally I’ve used some of the Anthropic models in it but found their cost massively outweighed the benefits for the type of usage we do.
I was using Sonnet 4.5 and 4.6 for a while but the newer models are a lot more expensive at the per-token pricing.
I wonder if Anthropic will follow suit given their campaign against distillation or if they'll stay quiet given their reliance on SpaceX (among others) for hardware.
> we’ve decided to hold the contract cancellation to the latest date we can while not providing future models to Cursor.
Ironically, as a Cursor and Claude subscriber, but not an OpenAI subscriber, this will push me back to Anthropic. I don't feel good about giving OpenAI money directly, but I've found switching to GPT 5.6 Sol now and again in Cursor to be useful. Now I'll probably just forget about OpenAI models.
Cursor is already kind of useless for third party models unless you're willing to spend thousands of dollars. It's only worth it if you're going to use mostly grok/composer.
Big reason we built boxes.dev around the model harnesses (Codex + Claude Code), so you can bring your own subscriptions.
Cursor will be fine after this, as they have their own first party models and can potentially use open weight models via API or their own hardware, which have gotten good enough to Opus and Fable quality now for many use cases.
This move seems to protect Astra against distillation. I wonder whether Astra will be released before or after 11/12.
I think Sam Altman has played a clever business move here, they can use this excuse immediately after the Hugging Face leaks and it's not going to be dismissed willy-nilly. Whereas long term they probably wanted to end their partnership with Cursor anyway. I bet Dario will be happy about this too, but maybe the compute deal prevents him from doing similar anytime soon.
Very interesting times we live in...
Seriously though, when the api providers start blacklisting cursor and they’re forced to swap to open weight models…
If that happens, what even is the difference between openrouter and cursor?
Strategically, OpenAI long-term will want to own the direct relationship with all their customers. As will most major AI labs.
Maybe if Claude joined along it would be more impactful. For better or worse though, Xai seems like its lining themselves up to handle being on their own for cursor.
> After Musk acquired Twitter, now part of SpaceX, the company broke (opens in a new window) the terms of our contract (alongside many others).
I have never seen one large company throw another large company under the bus without any legalese filters like this before. Wondering if OpenAI site got pwned. Or maybe we in some strange, alternative reality. I doubt even their LLMs would be this frank.
This provides a method, but the data looks stale and perhaps a bit thin compared to say, Cursor, or even AntiGravity data.
Do I smell a cursor-analogue from openAI?
So this is OpenAI following suit after Musk admitted to distilling their models.
This was bound to happen once Cursor decided to sell itself to a competing model provider.
It'll be interesting to see if Anthropic applies their ban to Cursor, or if that datacenter deal they signed with Musk changes anything.
That thread you linked suggested they were using it with cursor as part of their development process, not for distilling.
>"Hi team, I believe many of you have already discovered that anthropic models are not responding on cursor. According to cursor this is a new policy anthropic is enforcing for all its major competitors."
It's hard to imagine a 1B / month deal wouldn't.

If Claude pulls away from Cursor as well then Cursor is basically done.
