流式输出

启用流式

curl https://api.osp.io/v1/chat/completions \
  -H "Authorization: Bearer $OSP_A... \
  -d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "用三句话解释量子计算"}], "stream": true}'

响应为 SSE 流（text/event-stream）。

Python 示例

import requests, json

resp = requests.post("https://api.osp.io/v1/chat/completions",
    headers={"Authorization": f"Bearer {api_key}"},
    json={"model": "gpt-4o", "messages": [{"role": "user", "content": "hello"}], "stream": True},
    stream=True)
for line in resp.iter_lines():
    if line.startswith("data: "):
        data = line[6:]
        if data.strip() == "[DONE]": break
        content = json.loads(data)["choices"][0]["delta"].get("content", "")
        if content: print(content, end="", flush=True)

注意事项

• 流式无法与 response_format: json_schema 兼用
• Gemini/Claude 流式格式兼容 OpenAI SSE
