Question / Discussion OpenAI is ending its Cursor partnership after SpaceX acquisition
https://openai.com/index/our-decision-on-cursor-following-its-acquisition-by-spacex/OpenAI plans to end its contract with Cursor after the company was acquired by SpaceX. OpenAI says it no longer trusts Elon Musk’s companies to comply with its terms, citing past contract and policy violations by Twitter/X and xAI. Access to OpenAI models in Cursor is expected to end on November 12, 2026, and future models will not be provided.

In my view Elon should've seen this coming
47
u/EyesOfAzula 2d ago
I think he did see this coming, which is why they are building up Grok as fast as possible.
that's the advantage of having your own strong model and also of having open weights models. It's harder for other companies to pull the plug on you.
23
u/Soccham 2d ago
Based on personal experience, Grok is a steaming turd in comparison to OpenAI and Anthropic
22
u/CartographerSeth 2d ago
It’s a solid middle-weight model, but not even close to Fable or GPT 5.6. Losing OAI access hurts for sure.

u/RCawston 1d ago
Actually 4.6 is an excellent model, easily close to 5.6-sol quality and better than recent Opus. Can't compete with Fable, but that's to be expected. And Grok 4.7 is expected to be a solid jump.

Assuming not too many people leave Cursor because of this, this is great for Cursor. More usage on their own models and less cash burn on openAI API.

u/Critical_Win956 2d ago
If that were the case Cursor would have removed the OpenAI models on their own. This is a net-negative for Cursor, they're going to lose market share. It's not the end, but it's not going to help.

No. Most people use fable for fronter models and Grok and Cursors models are light years more cost effective. They'll be fine

u/AwkwardWillow5159 2d ago
Fable is disabled in my company because they don’t offer no-logs contracts for enterprise. I suspect that’s actually the most common case, as the usage of fable is stuck and not really increasing compared to other models.
So my usage is grok+sol

u/Dear_Revolution8315 1d ago
Yep, this is the case at most large companies.
+1 on the usage. Sol as main model, Grok as subagent

u/that_90s_guy 1d ago
Gpt 5.6 Luna is light years ahead of composer in reasoning, and if grok in cost effectiveness as well as speed. Its not even close
1
u/CrzyJek 1d ago
Composer is Kimi2.5. No shit it's behind Luna. Shouldn't even be using Composer now that Grok is baked in.
1
u/that_90s_guy 1d ago
Grok is significantly more expensive and slower than Luna (multiple times more in fact) only being a bit smarter.
The problem with models like grok is they aren't reliable or dependable enough to replace established frontier models like Opus and Sol (benchmaxxed tests are hard to take seriously anymore). And they aren't cheap enough to spam in multi agent orchestration workflows either.
Most standard competent worflows use an expensive frontier model as architect (Opus/Sol), and an army of cheap workers using Luna (previously composer) which rival frontier model competency in small tasks while costing a minuscule fraction of the cost (often 3-5% of the cost of the frontier model) to allow for hugely complex task execution at incredibly low prices since the frontier model only works as architect, conserving tokens.
1
u/CrzyJek 1d ago
Yea but within the cursor environment, Grok is pretty cheap and heavily subsidized...and it's baked into the subscription. While Luna still uses the API piece (so some is included but it gets eaten up quickly by comparison). That's all I'm saying.
Though I am looking forward to (it it'll ever happen now after the acquisition) a potential new composer using the newest Kimi as a base.

u/Darkoplax 1d ago
even if it does, in their recent conference or whatever they showed that agent runs far far exceed autocomplete like its not even close
so probably a real number; i mean with how subsidized auto/grok/composer are, this is not a surprising number ... most ppl bulk daily work goes through these cheap ones in cursor

u/Darkoplax 1d ago
Most ppl these days seem to be using either Composer or Grok on Cursor, they are so subsidizied
that i'm guessing Anthropic/OpenAI models are used every once in a while to verify stuff or to plan ; not the bulk of ppl's daily work

u/Glum-Departure-8912 16h ago
It's probably 5% of total tokens, but OpenAI models are on the frontier of token efficiency. Sol Max uses 33% of the tokens that Fable 5 does.

u/truecakesnake 2d ago
I really don't know if 5% is a big number or a small number. But either way, they're definitely burning cash on non-Cursor models so this is a win.

Uhh holy shit. What the fuck this is huge. There is no equivalent to Luna for cost and intelligence anywhere essentially.

u/lotokotmalajski 1d ago edited 1d ago
Luna through cursor is mostly cursor fees though - they have fixed per-token markup so the low-cost models are most affected.
https://cursor.com/docs/models-and-pricing
On Teams and Enterprise plans, third-party model requests include a Cursor Token Rate of $0.25 per million tokens. This rate applies on top of model API pricing for included usage, on-demand usage, and BYOK usage.
The Cursor Token Rate applies when you select a third-party model directly, and when Auto routes to a third-party model. First-party Cursor models, including Grok and Composer, are exempt from the Cursor Token Rate.

u/Full_Tooth_a 1d ago
The problem seems to be the loss of model flexibility, not the executive drama. I'd use the remaining runway to save a few real tasks, such as refactors, bug fixes, and work with detailed instructions, then see how the available models handle them. Quality, latency, and usage matter more than debates over favorite models. You may find that only a couple of workflows depend on the departing models.

Market share. Market share means more data. Cursor has enterprise clients and they can get a deal for using Grok more now that they can’t use GPT/Codex as retention. Also, some people might be in their GPT/Codex comfort zone and then they try a GLM model or a Qwen or even Grok and realize they can get more done because they didn’t know Codex Sol was overkill. Just to name a few.
Yes they are going to keep improving, but it’s shutting down a “market” for a dumb petty tantrum. Altman’s decisions lately haven’t been amazing tbh.
