Source: Artificial Analysis (artificialanalysis.ai). Measured variants: MiniMax-M2.1, speed on MiniMax; Claude Fable 5 (Max, Opus 4.8 Fallback), speed on Anthropic. Fetched October 13, 2026. Artificial Analysis runs Terminal-Bench 4.0 in its own setup, so its scores differ from the tbench.ai leaderboard.
MiniMax M2.1's 205K window cannot take 20% of coding-agent requests, so the comparison uses only requests both can take. Claude Fable 5 is superseded: Claude Fable 5.1 costs $0.24 per request. The price is OpenRouter's listed rate on October 13, 2026, which can be a third-party host's; MiniMax's own API may charge differently.
