Claude Haiku 4.5 vs Ministral 3 14B (Reasoning)

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

Claude Haiku 4.5 has the cleaner overall profile here, landing at 62 versus 60. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

Claude Haiku 4.5's sharpest advantage is in multimodal & grounded, where it averages 78.4 against 71.5. The single biggest benchmark swing on the page is MMMU-Pro, 82 to 71. Ministral 3 14B (Reasoning) does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.

Claude Haiku 4.5 is also the more expensive model on tokens at $0.80 input / $4.00 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 Haiku 4.5 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 Haiku 4.5 gives you the larger context window at 200K, compared with 128K for Ministral 3 14B (Reasoning).

Quick Verdict

Pick Claude Haiku 4.5 if you want the stronger benchmark profile. Ministral 3 14B (Reasoning) only becomes the better choice if mathematics is the priority or you want the cheaper token bill.
