Model capability probe

Z.ai: GLM 5.1 | streaming output

Whether Z.ai: GLM 5.1 supports streaming output cannot be decided from the name alone. Check model ID z-ai/glm-5.1, provider Zhipu AI (GLM), catalog params, modality, a lightweight runtime probe, and the error body together.

How to judge this capability

Whether Z.ai: GLM 5.1 supports streaming output cannot be decided from the name alone. Check model ID z-ai/glm-5.1, provider Zhipu AI (GLM), catalog params, modality, a lightweight runtime probe, and the error body together.

Model: z-ai/glm-5.1
Provider: Zhipu AI (GLM)
Capability: streaming output

How to prove it during checking

Read-only check. Detection data burns after 5 minutes.

Start with the catalog signal: runtime probe required, then verify with a real key in read-only mode.
The capability probe must bind model ID z-ai/glm-5.1; do not test another model from the same provider.
streaming output · supports frequency_penalty · supports include_reasoning · supports logit_bias · supports logprobs

Next action

Z.ai: GLM 5.1 streaming output should turn into an operator action: confirm sale tags, fill the capability matrix, change route, suggest a fallback model, or mark unsupported for now.
