> \* AWS Bedrock requires build tag: `go build -tags bedrock`. Set `api_base` to a region name (e.g., `us-east-1`) for automatic endpoint resolution across all AWS partitions (aws, aws-cn, aws-us-gov). When using a full endpoint URL instead, you must also configure `AWS_REGION` via environment variable or AWS config/profile.
<details>
<summary><b>Custom Headers (Web UI & config.json)</b></summary>
You can pass custom HTTP headers to your model API calls (useful for custom gateways, proxies, or specific provider features).
**In the Web UI:**
1. Go to the **Models** page and click **Add Model** or edit an existing one.
2. Open the **Advanced** section.
3. In the **Extra Headers** field, enter your custom headers in valid JSON format, for example:
```json
{
"X-My-Header": "value",
"Authorization": "Bearer my-custom-token"
}
```
4. Save the model.
**Directly in `config.json`:**
Add the `extra_headers` field to your model configuration:
```json
{
"model_list": [
{
"model_name": "custom-header-model",
"model": "openai/gpt-4o",
"api_base": "https://api.myproxy.com/v1",
"api_key": "sk-123",
"extra_headers": {
"X-My-Header": "value"
}
}
]
}
```
