GLM 5.2 accepts and produces text, operating with a context window of up to 1M tokens. It's well-suited for long-running agent scenarios, project-scale engineering tasks, and sophisticated multi-step automation.
Reasoning effort levels high and xhigh are available, with xhigh corresponding to maximum reasoning depth. The model excels at coding and tool use within extended tasks — it retains engineering context and adheres to conventions consistently throughout an entire development cycle, from defining requirements to multi-platform deployment, all within a single session.
