# Doubao Seed 2.1 Turbo

> ByteDance Doubao Seed 2.1 Turbo chat model, OpenAI-compatible.

豆包 Seed 2.0 Pro 是通过 Upmore OpenAI 兼容接口提供的对话模型。字节跳动 Seed 2.0 Pro 旗舰模型，推理能力最强。

## 核心能力

* **OpenAI 兼容** — 可直接使用 OpenAI SDK 接入，无需修改代码
* **最强推理** — 复杂多步骤任务的最佳选择
* **深度分析** — 擅长研究、规划和详细问题求解
* **流式输出** — 支持通过 SSE 实时流式返回内容

## 快速示例

  ```bash cURL theme={null}
  curl https://api.upmore.net/v1/chat/completions \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "doubao-seed-2-1-turbo",
      "messages": [
        { "role": "user", "content": "用简单的话解释量子纠缠。" }
      ]
    }'
  ```

  ```python Python theme={null}
  from openai import OpenAI

  client = OpenAI(
      api_key="YOUR_API_KEY",
      base_url="https://api.upmore.net/v1"
  )

  response = client.chat.completions.create(
      model="doubao-seed-2-1-turbo",
      messages=[
          {"role": "user", "content": "用简单的话解释量子纠缠。"}
      ]
  )

  print(response.choices[0].message.content)
  ```

  ```python 流式输出 theme={null}
  from openai import OpenAI

  client = OpenAI(
      api_key="YOUR_API_KEY",
      base_url="https://api.upmore.net/v1"
  )

  stream = client.chat.completions.create(
      model="doubao-seed-2-1-turbo",
      messages=[

      ],
      stream=True

  for chunk in stream:
      print(chunk.choices[0].delta.content or "", end="")
