description: Baidu Qianfan ERNIE model configuration
---
Option 1: Native integration (recommended):
```json
{
"model": "ernie-5.0",
"qianfan_api_key": "",
"qianfan_api_base": "https://qianfan.baidubce.com/v2"
}
```
| Parameter | Description |
| --- | --- |
| `model` | Default recommendation: `ernie-5.0`; also supports `ernie-4.5-turbo-128k`, `ernie-4.5-turbo-32k`, `ernie-x1-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-5.0` | Default recommendation; latest ERNIE flagship with the strongest overall capability |
| `ernie-4.5-turbo-128k` | Long-context and general chat |
| `ernie-4.5-turbo-32k` | General chat with a balanced context window and cost |
| `ernie-x1-turbo-32k` | Tasks that need stronger reasoning |
## Vision tool
After `qianfan_api_key` is configured, Agent mode can auto-discover Qianfan for the Vision tool. The recommended Qianfan vision model is `ernie-4.5-turbo-vl`:
```json
{
"tool": {
"vision": {
"model": "ernie-4.5-turbo-vl"
}
}
}
```
Option 2: OpenAI-compatible configuration:
```json
{
"model": "ernie-5.0",
"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.
