返回响应

流式返回 SSE,增量位于 choices[].delta。按事件拼接文本;结束事件为 data: [DONE]。以下 JSON 为单个事件的结构示例,不代表实际调用结果。

{
  "id": "chatcmpl_demo",
  "object": "chat.completion.chunk",
  "model": "claude-sonnet-5-5",
  "choices": [
    {
      "index": 0,
      "delta": {
        "role": "assistant",
        "content": "你好"
      },
      "finish_reason": null
    }
  ]
}

示例先设置 tokenba_API_KEY。JavaScript 使用 Node.js 20+,Python 安装 requests。流式示例的 Python 与 JavaScript 会逐段输出事件数据。代码中的 ID、文件名与令牌须替换为自己的值。

Chat 兼容响应按 choices 解析。明确配置原生 thinking 或 output_config 时使用 Messages,其内容块按 type 读取。Sonnet 5.5 迁移说明。
