Z.ai released GLM-5.3's weights on Hugging Face under a new license that requires large companies to undergo security review before hosting the model. The change marks a departure from the standard MIT license.

The new licensing requirement targets companies with over $10 billion in annual revenue, mandating they pass Z.ai's security review to deploy GLM-5.3. Smaller organizations and researchers can still access the open weights without restrictions. This conditional approach sits between fully open-source release and proprietary lockdown. Z.ai's move reflects growing tension in AI development between open access and security concerns, particularly around large-scale deployments. The GLM-5.3 model joins other high-capability weights released with custom terms in recent months. Other AI labs have experimented with similar conditional licensing, though enforcement mechanisms vary widely. Developers can access the model directly from Hugging Face, but enterprises planning production deployment will need to coordinate with Z.ai on security verification before proceeding.
