GLM-4.6 leads on more of the 3 benchmarks where both are measured — GLM-4.6 on 2, GPT-5 nano on 1. The remaining 6 of 9 tracked benchmarks cannot be compared: 5 have a result for only one of the two models, 1 for neither. Nothing on this page is estimated to fill those in.
Head-to-head
Measured on 3 of 9 tracked benchmarks for both models — GLM-4.6 leads on 2, GPT-5 nano leads on 1.

What remains uncertain
- GLM-4.6 has no published result on Chess Puzzles, GPQA Diamond, MATH Level 5, OTIS Mock AIME 2024-2025, SimpleQA Verified.
- 1 tracked benchmark has no published result for either model.
A missing result means Xentir has not found one published by the source it cites, not that the model performs badly. See Data Sources.
