设置 stream: true 启用流式输出，服务端以 SSE（Server-Sent Events）格式逐 token 返回。
Python
from openai import OpenAI
client = OpenAI(
api_key="sk-your-api-key",
base_url="https://api.ogmiao.com/v1"
)
stream = client.chat.completions.create(
model="glm-4.7-flash",
messages=[{"role": "user", "content": "写一首诗"}],
stream=True
)
for chunk in stream:
if chunk.choices[0].delta.content:
print(chunk.choices[0].delta.content, end="")SSE 数据格式：
