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 5.3 Preview Thinking
zai-org/glm-5.3:thinkingThe GLM-5.3 preview with higher reasoning enabled for harder long-horizon coding, autonomous agent workflows, and complex engineering tasks. 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.
