Why this result
Claude Opus 4.5 finishes one point ahead on BenchLM's provisional leaderboard, 71 to 70. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.
Claude Opus 4.5's sharpest advantage is in multimodal & grounded, where it averages 69.9 against 64.9. The single biggest benchmark swing on the page is MMMU-Pro, 70.6% to 78.1%. 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 4.5 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. MiniMax M3 gives you the larger context window at 1M, compared with 200K for Claude Opus 4.5.
