About this model

GLM-5.1 delivers a major leap in coding capability, with particularly significant gains in handling long-horizon tasks. Unlike previous models built around minute-level interactions, GLM-5.1 can work independently and continuously on a single task for more than 8 hours—autonomously planning, executing, and improving itself throughout the process—ultimately delivering complete, engineering-grade results. MiniRouter supports text input only.

Replaces GLM 5: input $1.05 → $1.47 per 1M (+40%), output $3.36 → $4.62 per 1M (+38%), same context window, max output 131K → 64K.

Platform-funded routing only. Caller BYOK credentials and OIDC-based upstream authentication are intentionally excluded; authenticate with a MiniRouter bearer key.

Captured parameters: max_tokens, temperature, stop, tools, tool_choice, reasoning, include_reasoning, response_format, structured_outputs.

Structured output: JSON Schema and JSON mode enforced on verified providers. How it works
