Ministral 3 8B vs Ministral 3 3B (Reasoning)

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

Ministral 3 8B finishes one point ahead overall, 32 to 31. 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.

Ministral 3 8B's sharpest advantage is in coding, where it averages 14.2 against 7.2. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 26 to 33. Ministral 3 3B (Reasoning) does hit back in agentic, so the answer changes if that is the part of the workload you care about most.

Ministral 3 3B (Reasoning) is the reasoning model in the pair, while Ministral 3 8B 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.

Quick Verdict

Pick Ministral 3 8B if you want the stronger benchmark profile. Ministral 3 3B (Reasoning) only becomes the better choice if agentic is the priority or you want the stronger reasoning-first profile.
