Google Gemini can be [compatible](https://ai.google.dev/gemini-api/docs/openai) with the 'openai' package. By utilizing this, CheapGPT can support the use of Google Gemini API Keys. You can change the 'provider' option on the extension's 'options' page to configure the settings.

When set to Gemini, the selection window will change to allow you to choose between the `gemini-flash-latest` and `gemini-flash-lite-latest` models. Additionally, the image generation model will change to allow selection between `Imagen 3` or `Imagen 4`. However, perfect compatibility with the 'openai' package is not guaranteed, so images can only be generated at the 1024x1024 size.
