GLM-5.2 is Z.ai's (ZhipuAI's) flagship model for long-horizon agentic and coding tasks. It features a truly usable 1 million-token context window — roughly 5× larger than its predecessor GLM-5.1 — and supports up to 131,072 output tokens per response. Built on the GLM-5 Mixture-of-Experts backbone (744B total parameters, 40B active), it offers two thinking-effort levels (High and Max) for complex multi-step coding and engineering workflows. GLM-5.2 is compatible with eight agentic coding tools out of the box, including Claude Code, Cline, and OpenClaw, via an Anthropic-compatible endpoint.
