GLM 5.3 Preview
zai-org/glm-5.3A preview of GLM-5.3 for long-horizon autonomous coding and engineering workflows. This variant defaults to the model's low reasoning tier for faster responses. While in preview, prompts and responses may be logged and used for training.
GLM 5.2
zai-org/glm-5.2GLM-5.2 is Z.AI's flagship model for long-horizon autonomous coding and engineering workflows. It is built to plan, execute, iterate, and optimize complex development tasks over extended runs. This variant keeps thinking disabled for faster direct responses.
