Introducing Composer 2 (cursor.com)

Cursor has announced the release of Composer 2, an advanced coding model that blends superior performance with competitive pricing, at $0.50 per million input tokens and $2.50 per million output tokens. This latest iteration demonstrates significant enhancements over its predecessors, scoring 61.3 on the CursorBench and achieving even higher metrics on specialized benchmarks like Terminal-Bench 2.0 and SWE-bench Multilingual. Notably, Composer 2's improvements are attributed to a robust pretraining process that strengthens the foundation for reinforcement learning, marking a substantial leap in coding capabilities compared to Composer 1.5 and 1. The introduction of a faster variant of Composer 2, priced at $1.50 per million input tokens and $7.50 for output tokens, positions it as a more affordable option compared to existing fast models, while still providing similar intelligence levels. Cursor is making this faster version the default option, encouraging users to adopt Composer 2 for their coding needs. This release is significant for the AI/ML community, as it not only showcases advancements in model performance and cost-efficiency but also highlights the ongoing evolution of AI capabilities in programming environments, offering developers more effective tools to enhance productivity.
