# Doubao Seed 2.0 Pro

> ByteDance's Seed 2.0 Pro flagship model with the strongest reasoning capabilities.

Doubao Seed 2.0 Pro is a chat model available through Cube AI via an OpenAI-compatible API. ByteDance's Seed 2.0 Pro flagship model with the strongest reasoning capabilities.

## Key Capabilities

* **OpenAI compatible** — Use the OpenAI SDK directly with no code changes
* **Best reasoning** — The top choice for complex multi-step tasks
* **Deep analysis** — Excels at research, planning, and detailed problem-solving
* **Streaming** — Supports real-time streaming output via SSE

## Quick Example

<CodeGroup>
  ```bash cURL theme={null}
  curl https://ai.cubeuaeai.com/v1/chat/completions \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "doubao-seed-2.0-pro",
      "messages": [
        { "role": "user", "content": "Explain quantum entanglement in simple terms." }
      ]
    }'
  ```

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

  client = OpenAI(
      api_key="YOUR_API_KEY",
      base_url="https://ai.cubeuaeai.com/v1"
  )

  response = client.chat.completions.create(
      model="doubao-seed-2.0-pro",
      messages=[
          {"role": "user", "content": "Explain quantum entanglement in simple terms."}
      ]
  )

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

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

  client = OpenAI(
      api_key="YOUR_API_KEY",
      base_url="https://ai.cubeuaeai.com/v1"
  )

  stream = client.chat.completions.create(
      model="doubao-seed-2.0-pro",
      messages=[
          {"role": "user", "content": "Write a short poem about the ocean."}
      ],
      stream=True
  )

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