zai-org/GLM-5.1-FP8
zai-org/GLM-5.1-FP8 is a zai-org record on this register. The Hugging Face model API lists the pipeline tag as text-generation. The safetensors index gives an exact parameter count of 753,910,024,032. Architectural context length (max_position_embeddings) is 202,752. The listed licence is mit. The Hub repository was created on 3 Apr 2026, which is the release date this register uses.
Primary source: the Hugging Face model card for zai-org/GLM-5.1-FP8. Fields below come from that card, the Hub model API, and the repository’s own config.json when those files exist. A field we cannot source is omitted rather than guessed.

How to run
Safetensors weights are on the Hugging Face repository. The parameter count on this page came from that index.
The repository name marks this record as FP8.
