Google Generative AI Conversation

The Google Generative AI integration adds a conversation agent powered by Google Generative AI in Home Assistant.

This conversation agent is unable to control your house. The Google Generative AI conversation agent can be used in automations, but not as a sentence trigger. It can only query information that has been provided by Home Assistant. To be able to answer questions about your house, Home Assistant will need to provide Google Generative AI with the details of your house, which include areas, devices and their states.

This integration requires an API key to use, which you can generate here.


To add the Google Generative AI Conversation integration to your Home Assistant instance, use this My button:

Top K

Number of top-scored tokens to consider during generation.

Maximum Tokens to Return in Response

The maximum number of words or “tokens” that the AI model should generate.
