Overview
- Cursor released the new programming models on March 19, optimizing them for long-horizon, multi-step coding through reinforcement-learning tuning and a 200,000-token context window.
- The system is designed to act like an AI software engineer by reading codebases, deciding changes, editing multiple files, and executing terminal commands within Cursor.
- Standard Composer 2 pricing is $0.50 per million input tokens and $2.50 per million output tokens, down from $3.50 and $17.50 in Composer 1.5, while the Fast tier is $1.50 and $7.50.
- Cursor added a cache-read discount intended to further reduce day-to-day developer costs.
- On Terminal-Bench 2.0, Composer 2 scored 61.7, topping Claude Opus 4.6 at 58.0 and trailing GPT-5.4 at 75.1.
