GLM-5.2

glm-5.2

GLM-5.2 is Z.ai’s flagship foundation model for long-horizon engineering tasks. It emphasizes a usable 1M-token context window for project-scale code and system context, more stable execution on long tasks, and better adherence to engineering standards. It is positioned for full development workflows, from requirements and repository analysis to implementation, testing, and multi-platform deployment, where large context and sustained agent behavior matter.
