How smart is GLM-4.6?

117 SI-IQ · 90% interval 106–128
Not ranked: too little data

GLM-4.6 is a model from Z.ai (Zhipu AI), Tsinghua University, released on Sep 30, 2025. Its SI-IQ is 117 (90% interval 106–128), estimated from 3 benchmark results by 2 independent evaluators.

This model has fewer than 5 independent benchmark results or fewer than 2 different evaluators, so it is shown 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.

Human preference (Arena)

On the Arena leaderboard, where people vote between two anonymous answers, GLM-4.6 has a rating of 1,424 (1,420–1,428) from 35,824 votes (published Oct 15, 2026). Human preference is a different measure from benchmark ability and is not part of SI-IQ. Arena (Hugging Face)
