  • If you have such a world changing technology, why sell an API when you can capture all the value yourself? That's what every provider is asking themselves.

    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.

  • What a shame for Cursor. I found it a great tool - I actually liked Composer 2.5; but now being bought by SpaceX has for a while left a bad taste - and they keep pushing Grok and now GrokBot.

    I took the 50% discount instead of cancelling - but with this I'll likely not renew.

    So sad to watch them go from great to mediocre in such a short time.

  • I 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 wants to add more models, they should host more open models.

  • While 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 probably just forget about OpenAI models.

  • I may be a rare Cursor user around here, but I am saddened by this news. The thing that keeps me using it is precisely the ability to switch between models: I usually do brainstorm/planning with Sol or Terra, then let Composer (free) deal with the implementation. For certain tasks I use Claude, which tends to be more expensive but sometimes saves me time.

    Using both OpenAI and Anthropic models, Cursor is cheaper than having two separate subscriptions, and their free tier of Composer is good enough. I will now have to reconsider my options.

  • It's always been clear to me that Cursor's business model of reselling others' APIs had its days numbered. Not necessarily because the providers would pull the plug, but because you wouldn't be able to compete with subsidized plans.

    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.

  • Is there some kind of alternative to Cursor in these terms

    - fast because the code is already indexed no need to start every prompt rediscovering the world with rg

    - in editor/vscode review much better than relying on git diff at the very end. You can click on next button to jump there. Quick edit in place. Or a quick prompt (seconds) to fix something small

    - in editor completion / quick edits, when you do things by hand.

    It seems that everyone loves agentic Claude code things these days but I don’t understand how you can review what it did and remain as much in the flow as you do with cursor.

    Also I find that incredibly slow. By the time Claude finished a prompt I could have done a few in cursor.

    And mind you, I’ve been wanting to use zed instead but the clunky vscode fork called cursor. But cursor has just a better UX for AI integration even though it’s slow and guzzle up RAM.

  • Anthropic 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 with Musk changes anything.
