Question

How do I add Google Gemini to Notion AI?

When I press on the "Auto" button I only see GPT-5 and Sonnet4.5

I've seen it in so many demo on YT and I have a Business Plan.

The Google Gemini AI model can be selected directly within Notion AI's settings. GPT-5 and Sonnet 4.5 are part of the standard Notion AI offering. Gemini became an option in a June 2025 update.
To manage available models:

1. Go to Settings → Notion AI.
2. Look for an option to add or manage AI models. Gemini 2.5 Flash and Gemini 2.5 Pro should be available in the AI chat.
3. Check for Notion app updates or refresh your Notion workspace if the models do not appear automatically.

If the integrated option is unavailable, it might be due to a regional rollout or plan-specific features. Google Gemini can still be integrated with Notion using third-party automation tools like BuildShip or n8n through their respective APIs. This requires more technical setup.
