Pairwise benchmark snapshot · Aug 17, 2026
This page compares GPT-5.6 Luna (OpenAI) and MiniMax M2.5 (MiniMax) using the latest snapshots we have as of Aug 17, 2026. On preference Elo, MiniMax M2.5 is ahead by 12 points (1,478 vs 1,466; lmarena (Aug 17, 2026)). On SWE-bench coding, MiniMax M2.5 resolves 75.8% versus 61.8% (swebench (Aug 17, 2026)). GPT-5.6 Luna streams faster (188 tok/s) while GPT-5.6 Luna is the cheaper output token ($0.6/1M). GPT-5.6 Luna 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.

Luna is the OpenAI fast/cheap 5.6 SKU after Jul 30. It is not Sol. Sort by price and TTFT, not Elo.
Tied near the top of official SWE-bench bash-only in Feb 2026. Coding lists should still see it.
High-volume agents that cannot pay Sol. Compare to Luna before you assume the new cheap SKU wins.
