Where these numbers come from
- Plans and prices — each vendor's own pricing page, checked 2026-10-27: GitHub Copilot, Google Antigravity. Usage allowances change often; check before you buy.
- Model scores — LiveBench coding and long-horizon agentic categories for the models each plan includes, live from the same data as the leaderboard. A tool's own agent loop matters too; these scores rate the model, not the tool.
- “Same work via API” — a heavy coding-agent month (40K tokens in, 4K out, 20K requests, 70% cached input) at OpenRouter list price, for comparing a subscription against paying per token.
