GLM-5.2
About GLM-5.2
GLM-5.2 is Z.ai’s most capable open-source model to date, built for long-horizon agentic engineering with a truly usable 1M-token context window. It keeps project state intact across ultra-long tasks, reducing the need to compress or discard context—the longer the task, the more it can remember and reason.
