Z.ai releases GLM-5.3's weights under a new license requiring companies with $10B+ in revenue over 12 months to pass Z.ai's security review to host the model (Frederic Lardinois/The New Stack)

Z.ai has released the weights for its GLM-5.3 model on Hugging Face, removing the MIT license. The new license requires any company with over $10 billion in annual revenue to obtain a security review from Z.ai before hosting the model. This change aims to restrict large-scale commercial use of the model without the review.
