Allowing the company or harness to dictate which models you use is crazy.

Re: Our decision on Cursor following its acquisition by SpaceX
#72While this isn't great for users it seems like a pretty standard circling of the wagons in preparation for the next phase in the battle for frontier AI dominance. 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 pr…
Why would you possibly allow companies to push you? You are the customer and you should control which models you use.

#73> As AI capabilities advance, we also have a new level of accountability to ensure our upcoming model, Astra, is being used in accordance with our terms. 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 Dar…
Is it really an excuse? As the release points out, musk admitted under oath to distilling OpenAI’s models to produce xai models on an ongoing basis. Whatever you think about goose for the gander wrt IP theft, I wouldn’t voluntarily do business with a competitor who was actively and brazenly flouting my terms, would you?
It's amusingly ironic to talk about "IP theft" in the context of AI models.

#74I don't see how it makes sense to use models outside of Grok or Composer in cursor unless you like the tooling to such degree that you're willing to pay out the nose for access to OpenAI and Anthropic to use with that tooling. And Codex is regularly scoring towards the top among harnesses, so you might as well use the best harness available for the given model. I'm happy with Grok and Composer in Cursor. If Cursor wa…
The reason it makes sense is because different models are better at different things. Allowing yourself to be locked in to a particular model by these companies is a bad idea and will lead to worse outcomes for yourself and the market as a whole.

Agreed. Wrapping token spend is great for pumping your revenue numbers (congrats to them on $60B!), but doesn’t seem sustainable over the long term. Big reason we built https://boxes.dev around the model harnesses (Codex + Claude Code), so you can bring your own subscriptions.
Surely the days of being able to “bring your own subscription” to a third party platform are also numbered?
On one hand, yes, it doesn't make sense to give out subsidized tokens forever.
On the other hand, subscriptions create lock-in in a way that API pricing doesn't.
I think a more likely end is that subscription value decreases over time because API pricing gets more reasonable, but subscriptions stay because they are a good way of getting money out of people consistently.

#76> We are making this choice because we cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk's companies violating contracts. > 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 wi…
And to announce it on a Friday night. Brutal.

#77Bummed, but I guess for me, doesn't mean cursor subscription ending though. Grok is a pretty amazing model for the speed and price on Cursor.

#78I guess I’m on the right track. https://news.ycombinator.com/item?id=49428835 If Claude pulls away from Cursor as well then Cursor is basically done.
I've been using Cursor with Grok 4.6 a lot over the last week or so. Grok Build as well. Both options are performing very well for me.

I’m not so sure… Claude backtracked on this when they tried it
They played pigeon on discless videogame consoles a time or two, too.
How long have you been in tech, outta curiosity?
Edit: great answer.
Re: Our decision on Cursor following its acquisition by SpaceX
#80Anthropic already banned xAI for very similar ToS violations earlier this year: https://x.com/kyliebytes/status/2009686466746822731?s=46 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 wi…
Your link doesn't suggest a violation of TOS, but rather a policy shift disallowing their major competitors to use their model for any use. 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 anthropi…
Cursor might have framed it that way at the time, but 4 months prior Anthropic cut OpenAIs access under the same clause in the ToS:
https://www.wired.com/story/anthropic-revokes-openais-access...
And a month before the OpenAI block, they blocked Windsurf for the same reason: https://www.forbes.com/sites/johanmoreno/2025/06/05/anthropi...
So its pretty clear the TOS had this clause prior to Jan 2026.
