How smart is Qwen3-4B?

77 SI-IQ · 90% interval 65–89
Not ranked: too little data

Qwen3-4B is a model from Alibaba, released on Apr 29, 2025. Its SI-IQ is 77 (90% interval 65–89), estimated from 1 benchmark result 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.
