Currently, the only robust option for integrating AI in n8n workflows is by using ChatGPT, which is not only pricey, but not secure from an European Union stand point. While you can use Microsoft Azure, that’s not as supported as native ChatGPT nodes.
Security and privacy are critical factors in the AI ecosystem, specially for B2B. Google provides extensive tools and guarantees on this respect like compliance with the GDPR, the Privacy Hub, CSE, Sec-Gemini, Model Armor, Apigee, SynthID or Advanced API Security.
If you review questions regarding AI, many are related to Google API issues. I had to create an HTTP Request node for sending images to Gemini. Also two more for interacting with Google Files. Crafting Google flavor JSON schemas. There are also some errors on function calling with Gemini, etc.
On a side note I see Gemini becoming the reference ecosystem for AI and Agent related tasks. Gemini 3 is around the corner and I think proactively working towards this direction will benefit n8n, users and companies alike.
