glm

Call the GLM API (GLM 5.3 and earlier GLM 5 and 4 series) through RunAPI using OpenAI-compatible Chat Completions. Use for GLM text chat, streaming, or an existing compatibility client that needs the conditional reference.

GLM on RunAPI

Use OpenAI-compatible Chat Completions at https://runapi.ai/v1 as the primary protocol.

Primary protocol recipe

Authenticate

Set OPENAI_API_KEY to a RunAPI API key and OPENAI_BASE_URL to https://runapi.ai/v1.

Send request

python

from openai import OpenAI
client = OpenAI(api_key="YOUR_RUNAPI_TOKEN", base_url="https://runapi.ai/v1")
response = client.chat.completions.create(
    model="glm-5.3",
    messages=[{"role": "user", "content": "Summarize this review."}],
)
print(response.choices[0].message.content)
print(response.usage)

For long output, call the same method with stream=True and stream_options={"include_usage": True}; consume every chunk through [DONE].

Verify result

Require final assistant content, a terminal finish_reason, and authoritative usage. A stream is complete only after its terminal usage chunk and [DONE].

Stop boundaries

Correct a rejected shape once using the structured error. Retry transport once only before any response or Usage and when replay is safe. Record a terminal error and stop without changing model or protocol. For glm-5.3, keep requests to text history on Chat Completions. Add tools, reasoning, structured output, or multimodal input only when the current RunAPI contract explicitly verifies that capability.

Compatibility protocols

Do not use compatibility protocols with glm-5.3; use the primary recipe. Load compatibility protocols only when an existing client requires Anthropic Messages or Gemini contents for an earlier compatible model.

GLM-5.3 capability boundary

Capability	Current behavior
Text history, sync, streaming	Supported through OpenAI-compatible Chat Completions
OpenAI Responses, Anthropic Messages, Gemini contents	Not supported for `glm-5.3`
Tools, reasoning controls, structured output, multimodal input	Not declared pending model-specific evidence
Usage	Preserve returned token and cache fields; never infer missing details
