Pairwise benchmark snapshot · Aug 16, 2026
This page compares GPT-5.6 Terra (OpenAI) and MiniMax M2.5 (MiniMax) using the latest snapshots we have as of Aug 16, 2026. On preference Elo, GPT-5.6 Terra is ahead by 70 points (1,548 vs 1,478; seed-bootstrap (Aug 16, 2026)). On SWE-bench coding, MiniMax M2.5 resolves 75.8% versus 70.4% (seed-bootstrap (Aug 1, 2026)). GPT-5.6 Terra streams faster (128 tok/s) while MiniMax M2.5 is the cheaper output token ($0.9/1M). GPT-5.6 Terra has the larger context window (1.1M tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.

Terra is OpenAI’s Sonnet-class invoice. Use it when Sol is too expensive and Luna is too small.
Tied near the top of official SWE-bench bash-only in Feb 2026. Coding lists should still see it.
