OpenAI To Cut Off AI Models For SpaceX-owned Cursor (reuters.com) 29

"OpenAI said on Friday that it plans to stop providing AI models to Cursor, the coding-tool company now owned by Elon Musk's SpaceX," reports Reuters: "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," OpenAI said in a blog post... However, Michael Truell, a co-founder of Cursor and now an executive at SpaceX, said on X that the company was speaking with the OpenAI team to resolve this issue.

Hours after OpenAI's announcement, Anthropic, which rivals both firms but has an ongoing partnership with SpaceX, said it planned to increase compute to support Claude models in Cursor, according to Tom Brown, one of the co-founders of the firm...

In its blog post, OpenAI said that X, formerly known as Twitter and now part of SpaceX, had breached the terms of its contract with OpenAI after Musk acquired the platform. "To work with a large partner like SpaceX, we typically rely on custom contracts to ensure compliance with our terms of service and that the integration provides for safety at scale," the AI company added.

The article also notes Elon Musk's response Saturday in a post on X.com: "I couldn't care less." He accused Altman and OpenAI President Greg Brockman of being "untrustworthy," while repeating his assertion that they "stole an open source nonprofit."

    This is clearly a corporate "fuck you" move, and both sides of the quarrel are shitheads, but I'm here for it. Insert the "let them fight" meme GIF here.

      Well yeah they're multibillion corporations, of course they are shitheads But this is not a corporate "fuck you", this is a corporate "uh you guys are working for our competition now, so..."

      No, it is siloization happening. We've seen it before and it has been predicted for this market as well. It's just capitalism in action, as much as people want it to be salacious drama.

        Unless they have a means to deal with the massive amounts of industrial espionage in the industry, any silo is purely temporary. I'm here for that too. I think the massive inability to keep secrets is the best defense we have against any one party or small cabal gaining dominance.

        • Yeah, it is very much a question if they will be successful in their attempts. But we all know they'll going to try as hard as they can.

      The enshittification of Cursor continues.

      Maybe this will force them to support more open models.

    "Open"AI closes off AI models to a competitor, okay.

    This is probably not really the end of GPT in cursor for interested people, but the end of GPT as one of the default options. If you subscribe to the (pay as you go) API, you get an URL you can enter into enter OpenAI-API client. Cursor just like almost every other tool are such clients and the only option OpenAI would have to prevent this is to server-side detect the Cursor system prompt, which seems unlikely (but not impossible). I think it is rather "If the user configures it manually, it's the user's fault"

    You can still consider if you want to invest into corn. When it pops it's not a bubble but delicious popcorn.

    Unless controlled, reviewed and improved by somebody very competent, very experienced and very careful, AI code is crap anyways. The largest identified (!) risk is now (besides security) that software gets more and more complex and eventually becomes unmaintainable due to complexity and technological debt. Obviously, that creeps up on people over a few years. But the end-result is catastrophic.

    • by Junta ( 36770 )

      More like 'neutral', Cursor is by no means the only path to vibe code and OpenAI's models are by no means the only models (in fact, generally viewed poorly in those circles). So OpenAI making it harder for Cursor users won't make a dent in the general scheme of things.

        The "good" does not come from the unavailability. The "good" comes from the change, making it a bit more clear that you cannot rely on availability with these tools.

  • Well that doesn't sound very Open to me.
  • this is going to be such a short period in history.

  • OpenAI can't even use OpenAI products within it's own terms of service. Aren't their agents out there breaking into other systems illegally right now?
  • OpenAI is lucky they came out first, Claude better for programming and Grok is better for 'googling.'
  • That's what happens when you pay $60B for a VS code fork.
