About GLM-5.1

The GLM-5 repository hosts language models for agentic engineering and coding, covering GLM-5, GLM-5.1, GLM-5.2, GLM-5.3 and GLM-5.3-Flash. The repository contains code, examples, resources, skill files, and English and Chinese README files.

Described uses include repository generation, terminal tasks, vulnerability discovery, and long-horizon work, with GLM-5.2 described as supporting 1M-token context. GLM-5.3-Flash is described as using hybrid sparse and linear attention and a 30T-token multimodal pre-training corpus. API services for GLM-5.3 and GLM-5.3-Flash are listed via the Z.ai API Platform.
