Snapshot facts · download the public dataset · methodology
Superseded by GLM 5.2 FP8.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.
Providers
Uptime measured over the last 30 minutesCurrent provider status is unavailable.
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.
