Surprised this got pushed off the front page so quickly! It’s exciting to see what the Cursor team has been able to do with significantly fewer resources than the frontier labs.

I do wish they weren’t joining xAI. Something tells me there will be a contingent of researchers that departs Cursor if that merger is consummated.

It set off the flamewar detector, a,k.a. the overheated discussion detector. We'll turn that off.

Thanks, dang! The blog post[1] might be a better source than the twitter thread. Also I regret my typo above (lab -> labs) but too late now!

Thanks! I had been just about to add that maybe the link wasn't the most informative. We've switched it now from https://twitter.com/cursor_ai/status/2056415413077233983.

As for the typo, s's are cheap and I've added one :)

Can you please train Qwen 3.5 like 0.8B to 9B using the same training techniques

It's always great that more companies are throwing their hat in the ring, especially focusing on value (latency + intelligence + cost)

this feels super bullish on cursor/spacexai's ability to train a frontier level model. could be truly SOTA on coding given that their RL data is this powerful

It's a bit odd that they're not comparing it against Sonnet

I don't think so. They're comparing it to the highest tier available models from Anthropic and OpenAI. Generally speaking, Opus is better than Sonnet in almost every way, so why have the redundancy?

Price to performance?

The tweet specifies that the new model is geared towards long-running tasks, which is what you'd use a model like Opus for anyway.

Did they just upgrade Kimi 2.5 to 2.6?

still uses 2.5

I don't know why their model isn't on Openrouter yet. They must not have enough capacity to offer it.

Their previous Composer was already marketed as a cheap model capable of competing with SOTA on most tasks. The evals they shared back then backed this up but in my day-to-day usage it fell short across the board. Canceled my cursor subscription and switched to Claude Code a few weeks ago. It has its own shortcomings but in terms of model capability and UX quality Cursor will have a hard time competing in the long term. Elon Musk will be a very good way out for them.

Congratulations on the launch! I'm interested in trying Cursor but it's very confusing what I should buy. What does the Pro $20 plan get me in usage if I only use Composer 2.5? How fast is the model?
darkwi11ow 14 hours ago|
I use $20 plan on daily basis for more than a year now, and have yet to exhaust that limit. The plan includes $20 in api costs for non-Cursor premium models and $20 for Composer and Auto models provided by Cursor themselves.

That said, I am pretty old-fashioned coder and use LLM mostly to overcome the blank page problem, which means I review and often rewrite LLM output by hand and avoid prompt loops for a single task.

People who are aiming to not read code any more might find this $20 plan lacking for their needs, however for my needs it fits perfectly.

The limits are probably even higher than that, i seem to get about 100$+ of usage on composer and about 45-50 usd on non composer models
