Cursor's Composer 2 outperforms Anthropic's Claude Opus 4.6 on coding benchmarks (61.7% vs 58.0%) while costing one-tenth the tokens ($0.50 vs $5 per million input). Same day, OpenAI acquired Python toolmaker Astral for Codex. The AI coding space appears to be shifting from model competition to infrastructure control.
