Composer 2 is out! Cursor is an example of a new type of company, not a pure app maker and not a model provider. Our aim is to build the most useful coding agents by combining the best API models and our domain-specific models.

fun fact about the Composer 2 RL run: we ran training distributed across 3 (sometimes 4) different clusters around the world using some secret sauce we built together.

We were able to significantly improve the model quality and cost to serve. These quality improvements come from our first continued pretraining run, providing a far stronger base to scale our reinforcement learning. [image]

Cursor have released Composer 2, a frontier-level coding model with higher token efficiency, and a faster default variant Looks like the rumor going around about it beating Opus 4.6 was in regard to Terminal-Bench 2.0, the only benchmark score they released aside from their own […

Composer 2 has been my daily driver for the past few weeks. It took a lot of self control to not post about how much I love using it for work. Give it a try, you won't regret it. Your wallet will thank you too.

Composer 2 just dropped in Cursor - i got early access for a few days and here are my first impressions: - it's very very fast so it feels amazing for sync coding or potentially as a daily driver - i've been using it for “flow-state coding” alongside Cursor Tab which has been

Cursor just launched Composer 2 - their own model. It's 10× cheaper than Opus 4.6 and supposed to rival it. I've been using it for a few days, I don't have any skewed graphs to show you but from a pure vibes POV I can tell you it's pretty good™ My litmus test right now is if it…

Open weight base models + incredible ML teams in a specific niche can create immense value. Congrats to all my friends on the cursor research team! (they said they did continued pretraining to enable effective scaled RL, super fun)

composer 2 is here beats opus 4.6 in terminal bench 2.0 input 0.5/M, 2.5/M output there's a faster variant too which has 3x price than normal variant. [image]

It's frontier-level at coding, priced at: - Standard: $0.50/M input and $2.50/M output - Fast: $1.50/M input and $7.50/M output [image]

got to test drive composer the last couple days and, man, performance vs cost is unmatched here.

I've been using this model for a while and while it's not quite as good as GPT 5.4, it's much faster and cheaper
