Reasoning is always enabled. Supports low, high, and max effort; image input is not supported.
Suggested starting role: complex planning. Always-on reasoning, complex coding, and long-running agent support make GLM a lower-cost planning candidate. It is text-only, so choose another model if the task needs image input. This is editorial guidance, not a benchmark score.
