[GLM-5.3 by Zhipu Officially Open-Sourced: Replacing MIT, Billion-Dollar Model Service Providers Must Undergo Security Review] Beating AI News Flash: Zhipu has officially open-sourced its flagship model GLM-5.3 with 744B parameters, and FP8 and BF16 weights are now available on Hugging Face. Unlike the previous generation GLM-5.2, this time the MIT license has been replaced with the new 'GLM-5.3 License.' The new license remains relatively permissive for regular developers, allowing usage, modification, distribution, deployment, fine-tuning, and even commercialization of the model and its derivatives. However, Zhipu has added a specific restriction for large 'Model-as-a-Service' companies: if a company and its affiliates generate a total revenue exceeding $10 billion over any consecutive 12-month period, they must first pass Zhipu's security review before commercially using GLM-5.3. Regular products embedding the model into specific functionalities are not subject to this restriction. GLM-5.3 was actually released two weeks ago, but Zhipu decided to conduct additional security evaluations and reinforcements due to the model's network security capabilities exceeding expectations before making the weights publicly available. The model now supports deployment on frameworks such as SGLang, vLLM, Transformers, and KTransformers. [Original Link]
