ERNIE - CowAgent

Option 1: Native integration (recommended):

{
  "model": "ernie-5.1",
  "qianfan_api_key": "",
  "qianfan_api_base": "https://qianfan.baidubce.com/v2"
}

Parameter	Description
`model`	Default recommendation: `ernie-5.1`; also supports `ernie-5.0`, `ernie-x1.1`, `ernie-4.5-turbo-128k`, `ernie-4.5-turbo-32k`
`qianfan_api_key`	Qianfan API key, usually starting with `bce-v3/`
`qianfan_api_base`	Optional, defaults to `https://qianfan.baidubce.com/v2`

Model Selection

Model	Use Case
`ernie-5.1`	Default recommendation; latest ERNIE flagship with the strongest overall capability
`ernie-5.0`	Previous-generation flagship with excellent overall capability
`ernie-x1.1`	Deep-thinking reasoning model with lower hallucination and stronger instruction following / tool calling
`ernie-4.5-turbo-128k`	Long-context and general chat
`ernie-4.5-turbo-32k`	General chat with a balanced context window and cost

Vision tool

Once qianfan_api_key is configured, Agent mode can auto-discover Qianfan for the Vision tool:

When the main model itself is multimodal (e.g. ernie-5.1, ernie-5.0, ernie-x1.1, ernie-4.5-turbo-vl), images are handled directly by the main model with no extra setup.
When the main model is text-only (e.g. ernie-4.5-turbo-128k), the Vision tool automatically falls back to ernie-4.5-turbo-vl.

To force a specific Vision model, set it explicitly in config.json:

{
  "tools": {
    "vision": {
      "model": "ernie-4.5-turbo-vl"
    }
  }
}

Option 2: OpenAI-compatible configuration:

{
  "model": "ernie-5.1",
  "bot_type": "openai",
  "open_ai_api_key": "",
  "open_ai_api_base": "https://qianfan.baidubce.com/v2"
}

Prefer qianfan_api_key for new configurations. Existing wenxin, wenxin-4, baidu_wenxin_api_key, and baidu_wenxin_secret_key configurations remain supported.
