GLM 5.3 Preview

zai-org/glm-5.3

A 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:thinking

The 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-5.2

GLM-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.

GLM 5.2 Thinking

zai-org/glm-5.2:thinking

GLM-5.2 with thinking enabled for harder long-horizon coding, autonomous agent workflows, complex engineering optimization, and real-world development tasks.

GLM Latest

zai-org/glm-latest

Compatibility alias that routes to the newest thinking GLM model. Currently routes to GLM 5.2 Thinking.

GLM 5.1

zai-org/glm-5.1

GLM-5.1 is Zhipu's next-level open source model, ranking #1 in open source and #3 globally across SWE-Bench Pro, Terminal-Bench, and NL2Repo (as of April 2026). Built for long-horizon tasks, it can run autonomously for up to 8 hours. Run at FP8.
