Pick Mistral Medium 3 if you want the stronger benchmark profile. LFM2.5-350M only becomes the better choice if you want the cheaper token bill.
Mistral Medium 3 is clearly ahead on the aggregate, 52 to 39. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Mistral Medium 3's sharpest advantage is in knowledge, where it averages 70.1 against 23.8. The single biggest benchmark swing on the page is MMLU-Pro, 20.0% to 77.2%.
Mistral Medium 3 is also the more expensive model on tokens at $0.40 input / $2.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for LFM2.5-350M. That is roughly Infinityx on output cost alone. Mistral Medium 3 gives you the larger context window at 128K, compared with 32K for LFM2.5-350M.
BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.
Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
