Zhipu GLM-5.3 API is officially launched today.

The GLM-5.3 API from Zhipu has been officially launched, excelling in complex coding, network security, and long-term tasks. It scored 60 points in the AA Comprehensive Intelligence Index, placing it on par with closed-source flagships like Claude Fable 5 and GPT-5.6 Sol, and tying for first place among open-source models with Kimi K3. GLM-5.3 achieves state-of-the-art performance with a smaller parameter size and the lowest cost per task, while maintaining the same pricing as its predecessor. The model weights will be open-sourced next Friday. It is currently integrated with coding platforms such as ZCode and its API is available for use.
