GLM-5.2 · orcarouter

GLM-5.2 is Z.ai (Zhipu AI)'s flagship model for the era of long-horizon tasks. It pairs a truly usable 1M-token context window with up to 128K output tokens, letting it hold project-level engineering context, execute long-running tasks more reliably, follow engineering standards more consistently, and carry a task from requirements through to multi-platform deployment in a single run. It is a text-in / text-out model with hybrid reasoning controlled by reasoning_effort (high / max; deep reasoning by default) and native tool calling. Built coding-first as the latest in the GLM-5 line, GLM-5.2 launched on the GLM Coding Plan with standalone API access and MIT-licensed open weights following shortly after. It targets repo-scale agentic coding, autonomous multi-step engineering workflows, and complex long-horizon delivery.
