How smart is Mistral Small 4?
Mistral Small 4 is a model from Mistral AI, released on Mar 16, 2026. Its SI-IQ is 96 (90% interval 83–108), estimated from 2 benchmark results by 1 evaluator.
Data as of Oct 18, 2026 · method 1.0.0
A model is ranked when its results come from at least 5 benchmarks (the two GPQA Diamond runs count as one) in at least 3 areas, from at least 2 different evaluators, and its versions are released no more than 60 days apart. This model does not meet that yet, so it is shown with a provisional estimate but not ranked.

Ability by area (SI-IQ, 90% interval)
Every benchmark result we used
Each score is one value exactly as the source published it: for Epoch AI the best of its run settings, for OpenRouter the median hosting provider (the developer's own hosting when it ran the test). “Implied SI-IQ” is the ability that this single result points to; the overall SI-IQ is their precision-weighted average.
