GLM-5.3: Frontier Coding with Emergent Cyber Capabilities
Z.ai has released GLM-5.3. The only improvement on the model is the amount of post-training performed. Z.ai continued scaling on its stack with more environments, more diverse tasks, and more compute, resulting in a model that is much better at complex coding and long-horizon tasks. Every gain comes from post-training.
