💻Cursor Composer 2 Launches with 50% Cost Reduction and Multi-File Workflows

The Rundown: Cursor released Composer 2, a new coding model using reinforcement learning that scores 61.3 on CursorBench while cutting costs to $0.50/M input tokens for multi-file development tasks.

The details:

  • ●Composer 2 achieves 61.3 score on CursorBench using reinforcement learning on long-horizon coding tasks
  • ●Pricing starts at $0.50/M input tokens and $2.50/M output tokens in standard mode
  • ●Faster variant costs $1.50/$7.50 per million tokens and becomes the default editor model
  • ●Cursor is also training its own frontier model to reduce dependence on third-party AI providers
Why it matters: The dramatic cost reduction and performance gains in AI coding tools are accelerating software development velocity, meaning technical founders can build faster while non-technical founders face increasing pressure to adopt AI-powered development workflows.
