Pick Claude Opus 5 if you want the stronger benchmark profile. MiniMax M3 only becomes the better choice if you want the cheaper token bill or you would rather avoid the extra latency and token burn of a reasoning model.

Confidence note. This is a partial-evidence comparison with 22 shared benchmark results across 5 evidence categories; 3 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.

Why this result

Claude Opus 5 is clearly ahead on the BenchAlign aggregate, 85.88 to 68.8. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Claude Opus 5's sharpest advantage is in agentic, where it averages 90.8 against 72.3. The single biggest benchmark swing on the page is OfficeQA Pro, 66.9% to 45.1%.

Claude Opus 5 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. Claude Opus 5 is the reasoning model in the pair, while MiniMax M3 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use.
