Why this result

Claude Opus 4.6 is clearly ahead on the provisional aggregate, 84 to 70. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Claude Opus 4.6's sharpest advantage is in multimodal & grounded, where it averages 77.3 against 64.9. The single biggest benchmark swing on the page is SWE-bench Pro, 53.4% to 59%. MiniMax M3 does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.

Claude Opus 4.6 is also the more expensive model on tokens at $5.00 input / $25.00 output per 1M tokens, versus $0.30 input / $1.20 output per 1M tokens for MiniMax M3. That is roughly 20.8x on output cost alone.
