GLM-5.3 · orcarouter

GLM-5.3 is Z.ai (Zhipu AI)'s latest flagship model for complex software engineering and long-horizon agentic tasks. It delivers roughly a 50% improvement in coding experience over GLM-5.2, matches Mythos 5 on selected cybersecurity capabilities, and strikes a better balance between raw performance and token efficiency. It is a text-in / text-out model built for repo-scale coding, autonomous multi-step engineering, and agent workflows that must stay coherent over long horizons. GLM-5.3 uses the same API surface as the GLM-5 line with two changes callers must handle: thinking is always on (thinking.type only accepts enabled; passing disabled now fails the request), and reasoning depth is controlled by reasoning_effort with values low / high / max, defaulting to max. It supports native tool calling and structured JSON output, and speaks the OpenAI-compatible chat-completions format.
