We plan to eventually have another model at that weight class, but right now trying to train the best possible model.

Probably can't advance frontier math yet, yeah. But please let us know other places you want to see Grok improve for future models!

We are and will continue to.

(I work on Grok) This isn't allowed. CSAM / deepfakes are against our acceptable use policy.

(I work on Grok) We've been working on teaching the model how to reason about great visual design principles. Obviously this is hard and somewhat subjective, but through a combination of writing down these principles (e.g. how to think

It works with the highest tier Cursor/Grok accounts during the beta.

It's quite a bit different, namely that ChatGPT Work has both local conversations and cloud agents. But for each cloud agent, you are spinning up and tearing down a new VM each time. This is an always-on Linux box, which stays logged i

(I work at Cursor) We score well on Terminal-Bench and SWE-bench Multilingual. DeepSWE, not so great yet, as it's more for very long-horizon tasks. We're planning to include more public benchmarks in our next model release.

(I work at Cursor) When Composer 2.5 launched, we initially scored very competitively on AA's composite benchmark. I believe 3rd place overall. They have recently updated to use DeepSWE, which has more of a focus on very long-horizon t

(I work at Cursor) CursorBench includes many evals from actual engineering tasks from the Cursor team, which include our private codebase. This codebase is held-out from training so models haven't seen it, including Composer.

Will do. On it.

(I work at Cursor) Sorry about this, we should have made this more clear. The new privacy mode is needed because we have to store some state to enable running agents in the cloud. If you don't want to use cloud agents, you can continue

Glass was a codename while the UI was in early alpha with testers. It redirects to download now because there is no special link anymore. It's just part of Cursor 3 itself.

I'm an engineer at Cursor, can try to clarify questions here. > I wish they'd keep the old philosophy of letting the developer drive and the agent assist. Even when I'm using AI agents to write code, I still find myself sp

We used a Kimi base, with midtraining and RL on top. Going forward, we'll include the base used in our blog posts, that was a miss. Also, the license is through Fireworks: https://x.com/Kimi_Moonshot/status/20

Are there other coding benchmarks we should include next time? We included Teminal-Bench 2.0 and SWE-bench Mulitilingual. We don't plan on reporting SWE-bench Verified, for similar reasons to OpenAI: https://openai.com/

You can disable this if you want, it's under "Inline Diffs" in the Cursor settings.

We've found it to be a strong mix of speed and intelligence. It scores higher than Sonnet 4.5 on Terminal-Bench 2, maybe we will post more on this later.

There's a setting to turn this off if you prefer (Cursor Settings > Agent > Attribution).
