Mistral AIMinistral 3 3B
Ministral 3 3B is a Mistral AI open-weights model, released 2 Dec 2025. Its best configuration ranks #739 of 785 on the BenchLeader Index at 37.0 ±3.7, in the lower half. The ± is the point: 169 other configurations score within that range, so they and this one cannot be told apart on quality alone — price and speed are what separate them. It scores highest in reasoning (41) and lowest in multimodal (20). At $0.100 per million tokens blended it is among the cheapest fifth of ranked models. Output speed of 207 tokens per second puts it in the fastest quarter, with a first answer in 0.7 s. Last measured 2 Dec 2025.stale: no new result in six months

How its index has moved
9 Sept 2026 to 21 Oct 2026The index is recomputed from scratch every day, so a line moves when a new benchmark result lands, when a publisher revises a score, or when the models it is normalised against change. Early movement usually means the score is still settling.
