Cursor Composer


I'm thrilled to pull back the curtain on Cursor Composer, this brand-new agent model that's setting a new standard for software engineering intelligence and speed.

On their internal benchmarks, Composer doesn't just pass the test—it crushes it. We're seeing frontier coding results at a generation speed that is a stunning four times faster than comparable models. That means smarter solutions delivered in a fraction of the time.

How did they do it? They trained Composer to tackle real-world software engineering challenges within massive, complex codebases. During training, the model was equipped with a full suite of production search and editing tools, forcing it to learn how to efficiently solve a diverse range of truly difficult problems.

The final result is a powerful, large-scale model—an agent optimized for high-speed, real-world use right here in Cursor. Get ready for a massive boost to your workflow!
