glm-5.3-el · poe

GLM 5.3 is Z.ai's flagship coding and agentic model, built on the same base as GLM 5.2 with post-training gains in complex software engineering and long-horizon agent work. It accepts text input with a 1M token context, always-on reasoning at low, high, or max effort, native web search, and function calling. This bot supports optional parameters for additional customization.
