Introducing Cursor 2.0. Our first coding model and the best way to code with agents.
Composer is a frontier coding model that completes tasks in under 30 seconds.

Easily run the same prompt across models for maximum intelligence.
With a built-in browser, agents can now run and test their code.
Turn speech into code with voice mode.

12 hours of working with Composer on html and css. 12 hours wasted, broke tons, had to restore entire site from backup. Good job guys. 🙂

For benchmarking purposes, it sounds like Composer falls behind top end models, but excels in speed and likely cost. Would be interesting to test planning with a 'best frontier' model and then executing with Composer while using side by side agents with a Codex or Claude

I love this because its so fast, usually when i send a prompt to sonnet or wtvr it takes 2-3 minutes for it to complete which is enough time for me to get stuck scrolling on twitter, not anymore tho!

so far I'm impressed with this model. note: ran into an issue where it tried fixing its own syntax error during a file edit, it tried a couple times then thought to checkout the file and try again. NICE! @ellev3n11 @ericzakariasson amazing work

Composer is super fast but it's code error rate is... Something.

Nice one Cursor folks, funny to know you adopted the same name we adopted for our major model and platform at @autohand_ai

Delilik. Aynı ajan birden fazla iş parçacığını paralel yazsa bile (ki bu daha çok işime yarardı) review yapacak olan ben olduğum için, hepsinin hızı benim review hızım kadar şuan. @claudeai 'ın yeni bir sonnet modeli çıkarmasını dört gözle bekliyorum Dario beyden @DarioAmodei 👀

what a stupid layout, normally agent, activity bar, and first side panel (file browser / extensions) is on the left now everything flips in agent mode exactly opposite, and looks like it is even hard coded as neither GUI menu nor 'settings.json' can change that

Prix et efficacité compare à sonnet 4.5 @grok ?

Why did you steal the name composer from PHP composer?

Incredibly fast AI coding! This is transforming development speed. #AI #CodingTools
