Introducing Composer 2
Summary
Cursor has made Composer 2 available as a coding model in Cursor. It is priced at $0.50/M input and $2.50/M output tokens, with a faster variant priced at $1.50/M input and $7.50/M output tokens. The release reports higher scores across CursorBench, Terminal-Bench 2.0, and SWE-bench Multilingual, with Composer 2 scoring 61.3, 61.7, and 73.7, respectively. Its training combines a first continued pretraining run with reinforcement learning on long-horizon coding tasks, allowing it to handle challenges requiring hundreds of actions. Composer 2's standard pricing and included usage pool on individual plans are presented alongside the faster option, which is set as the default.
Context
The release addresses coding quality and model cost, with stated improvements on measured benchmarks and pricing intended to combine intelligence with lower cost.
Approach / What changed
Composer 2 uses a first continued pretraining run to build a stronger base, followed by reinforcement learning on long-horizon coding tasks. The release also offers standard and faster pricing variants.
Takeaways
Composer 2 scores 61.3 on CursorBench, 61.7 on Terminal-Bench 2.0, and 73.7 on SWE-bench Multilingual.
The model is trained with continued pretraining followed by reinforcement learning on coding tasks that can require hundreds of actions.
The faster variant has the same stated intelligence as Composer 2 and costs $1.50/M input and $7.50/M output tokens; it is the default option.
