## Using Non-OpenAI Models in NextChat

NextChat natively supports the OpenAI API format.\
To use models from other providers (such as Claude or Gemini) through AI Gateway, you must add them as **custom models** using an OpenAI-compatible configuration.

In **Settings > Custom Models**, add a model using the following format:

```
+<model_name>@OpenAI
```

**Example**

```
+claude-3-opus-20240229@OpenAI
```

**Explanation**

* `<model_name>`\
  The actual model name supported by AI Gateway.
* `@OpenAI`\
  Indicates that NextChat should call this model using the OpenAI-compatible API format, even if the underlying model is provided by a different vendor.

AI Gateway translates the OpenAI-compatible request into the appropriate provider-specific API call.

This approach allows NextChat to use multiple AI providers through a single OpenAI-compatible interface exposed by AI Gateway.
