Visit Cursor Composer →Pros & Cons
✓ Key Strengths
- ~250 tokens/sec — Cursor claims ~4x faster than frontier models
- Much cheaper per completed task on Cursor's own infra
- Purpose-built for Cursor's agent harness (multi-file diffs, tool calls)
- Ideal for running many parallel agents across git worktrees
✗ Could be better
- Benchmark claims are self-reported by Cursor, not independently verified
- No public API — can't be used or tested outside Cursor
- Visibly weaker than Sonnet 4.5 on genuinely hard reasoning (concurrency bugs, cross-service migrations)
