by christophernhill-mit - opened

The blog post at z.ai/blog/glm-5.1 states "GLM-5.1 is released as open source under the MIT License," and the Hugging Face model cards for GLM-5.1, GLM-5, GLM-5.1-FP8, and GLM-4.7 all carry license: mit in their metadata. However, none of these repositories contain an actual LICENSE file with the MIT license text and copyright notice.

A few specifics:

  • No LICENSE file exists in any of the Hugging Face weight repositories (GLM-5.1, GLM-5, GLM-5.1-FP8, GLM-4.7). The only license indication is the YAML frontmatter tag.
  • The GitHub code repository (github.com/zai-org/GLM-5) contains an Apache-2.0 license with "Copyright 2026 Zhipu AI," which is a different license from what the weight repos and blog indicate.
  • No copyright notice accompanies the MIT designation anywhere. A valid MIT license requires a Copyright (c) line.

Could someone clarify:

  1. Are the model weights intended to be MIT-licensed? If so, could a LICENSE file with the full MIT text and copyright notice be added to the Hugging Face repositories?
  2. Is the Apache-2.0 license on the GitHub repo intentionally different from the MIT license on the weights, or is one of them an error?

Thanks all!

I will add it soon, please use it with confidence, it is under the MIT license.
Yes, this is intentional. Our GitHub repositories are all under Apache 2.0, and the model is under MIT license.
