[Zhipu GLM-5.3 Model API Officially Launched] According to the Sci-Tech Innovation Board Daily, in the early hours of August 19, Zhipu officially launched the API for its next-generation foundational model, GLM-5.3. Reportedly, this model excels in complex coding, defensive cybersecurity, and long-term tasks, achieving a score of 60 in the Artificial Analysis Intelligence Index. It has entered the global cutting-edge model capability range, standing on the same level as closed-source flagships like Claude Fable 5 and GPT-5.6 Sol, and tying with Kimi K3 as the top open-source model. The model has already been integrated into official products such as ZCode and the GLM Coding Plan. API pricing remains consistent with GLM-5.2, and the model weights are scheduled to be open-sourced next Friday.
