Register API Key in Porter AI

In Settings > Models, click the icon for Google Gemini and enter your API key.
Once you add your API key, Gemini model usage will be charged to your Google credits.

Add Models

Once you’ve registered an API key, you can add additional Gemini models beyond the default ones. Simply provide a display name (shown in chats) and the official Gemini model name.
You can find the list of model names available via API on the Gemini models documentation page. The highlighted section in the screenshot below shows the model name format.
For fine-tuned models, you can add them by entering the custom model name you configured.
