👨‍💻Cursor Composer 2 Delivers 50% Cost Reduction for Multi-File Coding

The Rundown: Cursor released Composer 2, a reinforcement learning-trained coding model that scores 61.3 on CursorBench while cutting costs to $0.50 per million input tokens.

The details:

  • ●Composer 2 uses reinforcement learning trained on long-horizon multi-file coding tasks
  • ●Priced at $0.50/M input tokens and $2.50/M output tokens in standard mode, with a faster $1.50/$7.50 variant
  • ●Cursor is also training its own frontier model to reduce reliance on third-party providers like Anthropic and OpenAI
Why it matters: The dramatic cost reduction and performance improvements in AI coding tools could democratize software development while forcing established players to compete on both price and capability.
