Then you can start using it.

## Special Cases (Using Non-OpenAI Models)

If you want to use non-OpenAI models in the Next Web client, follow these steps.\
First, ensure you have upgraded to the latest version (v2.13.0). In this version, a method for custom models has been added:

1. **Enter Custom Model Name**:
   * Since the Next Web client automatically determines the model provider based on the input model name, and the key provided by this site is only applicable to the OpenAI interface.
   * Therefore, when entering a custom model name, the format should be: “+‘desired model name’@OpenAI”.
   * For example, to use the gemini-pro model, enter the custom model name as: “+gemini-pro\@OpenAI”.
   * This way, you can manually direct the model provider to OpenAI.
2. **Confirm Selection**:
   * In the model selection interface, confirm that the manually added model (OpenAI) appears below.
