Z.ai
GLM‑5 is Z.ai’s flagship line for agentic engineering, programming, and complex reasoning. GLM‑5 supports a 200,000-token context window and up to 128,000 output tokens, enough for large repositories, technical documentation, and long sequences of tool calls. Faster variants in the line can reduce latency in interactive workflows. Choose GLM for code generation and refactoring, debugging, engineering analysis, multi-step agents, and process automation where reliably retaining a large body of context matters.
