Doubao (Volcengine Ark) supports text chat, image understanding, image generation (Seedream), and embedding. A single ark_api_key enables all capabilities.
All capabilities below can be configured in one place via the “Model Management” page in the Web Console, with no need to manually edit the configuration file.

​
Text Chat

{
  "model": "doubao-seed-2-0-pro-260215",
  "ark_api_key": "YOUR_API_KEY"
}
ParameterDescription
modelCan be doubao-seed-2-0-pro-260215, doubao-seed-2-0-code-preview-260215, doubao-seed-2-0-lite-260215, etc.
ark_api_keyCreate one in the Volcengine Ark Console
ark_base_urlOptional, defaults to https://ark.cn-beijing.volces.com/api/v3

​
Image Understanding

Once ark_api_key is configured, the Agent’s Vision tool automatically uses doubao-seed-2-0-pro-260215 to recognize images, with no extra setup required. To manually specify a Vision model: 
{
  "tools": {
    "vision": {
      "model": "doubao-seed-2-0-pro-260215"
    }
  }
}

​
Image Generation

{
  "skills": {
    "image-generation": {
      "model": "seedream-5.0-lite"
    }
  }
}
Available models: seedream-5.0-lite, seedream-4.5.

​
Embedding

{
  "embedding_provider": "doubao",
  "embedding_model": "doubao-embedding-vision-251215"
}
The default model is doubao-embedding-vision-251215 (multimodal embedding); the dimension (1024 or 2048) can be set via embedding_dimensions in the configuration file. After changing the embedding, run /memory rebuild-index to rebuild the index.
