某些 API 端点默认提供流式响应，例如 /api/generate。这些响应以换行分隔的 JSON 格式（即 application/x-ndjson 内容类型）提供。例如：

{"model":"gemma4","created_at":"2025-10-26T17:15:24.097767Z","response":"That","done":false}
{"model":"gemma4","created_at":"2025-10-26T17:15:24.109172Z","response":"'","done":false}
{"model":"gemma4","created_at":"2025-10-26T17:15:24.121485Z","response":"s","done":false}
{"model":"gemma4","created_at":"2025-10-26T17:15:24.132802Z","response":" a","done":false}
{"model":"gemma4","created_at":"2025-10-26T17:15:24.143931Z","response":" fantastic","done":false}
{"model":"gemma4","created_at":"2025-10-26T17:15:24.155176Z","response":" question","done":false}
{"model":"gemma4","created_at":"2025-10-26T17:15:24.166576Z","response":"!","done":true, "done_reason": "stop"}

禁用流式传输

对于支持流式传输的任何端点，可以通过在请求体中提供 {"stream": false} 来禁用流式传输。这样响应将以 application/json 格式返回：

{"model":"gemma4","created_at":"2025-10-26T17:15:24.166576Z","response":"That's a fantastic question!","done":true}

何时使用流式传输与非流式传输

流式传输（默认）:

• 实时响应生成
• 感知延迟更低
• 更适用于长篇生成

非流式传输:

• 处理更简单
• 更适用于短响应或结构化输出
• 在某些应用中更容易处理
