How smart is Gemma 3 12B?

73 SI-IQ · 90% interval 66–79
Not ranked: results from fewer than 5 benchmarks

Gemma 3 12B is a model from Google DeepMind, released on Mar 12, 2025. Its SI-IQ is 73 (90% interval 66–79), estimated from 5 benchmark results by 3 evaluators.

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 (results from fewer than 5 benchmarks). Its provisional estimate rests on 5 benchmark results and can change a lot when more results arrive.

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.

Human preference (Arena)

On the Arena leaderboard, where people vote between two anonymous answers, Gemma 3 12B has a rating of 1,342 (1,332–1,351) from 3,829 votes (published Oct 15, 2026). Human preference is a different measure from benchmark ability and is not part of SI-IQ. Arena (Hugging Face)
