Pick Claude Mythos 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.
Claude Mythos 5 is clearly ahead on the provisional aggregate, 99 to 76. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Claude Mythos 5's sharpest advantage is in multimodal & grounded, where it averages 92.7 against 64.9. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 88% to 66%.
Claude Mythos 5 is also the more expensive model on tokens at $10.00 input / $50.00 output per 1M tokens, versus $0.30 input / $1.20 output per 1M tokens for MiniMax M3. That is roughly 41.7x on output cost alone. Claude Mythos 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. Claude Mythos 5 gives you the larger context window at 1M+, compared with 1M for MiniMax M3.
Claude Mythos 5 is ahead on BenchLM's provisional leaderboard, 99 to 76. The biggest single separator in this matchup is Terminal-Bench 2.0, where the scores are 88% and 66%.
