Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Claude Opus 4.6 is clearly ahead on the aggregate, 85 to 60. 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 coding, where it averages 75.1 against 35. The single biggest benchmark swing on the page is LiveCodeBench, 75 to 33.
Claude Opus 4.6 is also the more expensive model on tokens at $15.00 input / $75.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Ministral 3 14B (Reasoning). That is roughly Infinityx on output cost alone. Ministral 3 14B (Reasoning) is the reasoning model in the pair, while Claude Opus 4.6 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 Opus 4.6 gives you the larger context window at 1M, compared with 128K for Ministral 3 14B (Reasoning).
Pick Claude Opus 4.6 if you want the stronger benchmark profile. Ministral 3 14B (Reasoning) only becomes the better choice if you want the cheaper token bill or you want the stronger reasoning-first profile.
