Superseded by GLM 5.2 FP8. It no longer holds a current-board position.
This separately configured or accelerated route is reviewed as the same underlying model identity as GLM 5.1. That canonical product owns rank and capability evidence; pricing, providers and other operational differences remain route-specific below.
OpenRouter endpoint status could not be refreshed. This model is not treated as currently served until a successful observation arrives.

Reported evaluation leads (1)
Not independent measurementStructured rows reported in this exact model repository at the pinned revision below. They are the publisher talking about itself: never measured evidence, never a score input on their own. Rows marked as used were laddered against independently measured peers inside the launch-card channel of this model's modeled placement, with the replay-measured optimism haircut applied; the others played no part.
