# ERNIE

> ERNIE model configuration (Baidu Qianfan)

Option 1: Native integration (recommended):

```json theme={null}
{
  "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`:

```json theme={null}
{
  "tools": {
    "vision": {
      "model": "ernie-4.5-turbo-vl"
    }
  }
}
```

Option 2: OpenAI-compatible configuration:

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

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