Foundation Models
Fallback generative AI model provider for the agent that generates draft rules and, once launched, Stage agent and automated routines; processes the instruction text (prompt) submitted by Customer’s users, the identifier or link of the designated spreadsheet, and the model output returned to the Services, under the Google Cloud Data Processing Addendum. Where the feature uses content from accounts or spreadsheets connected to the Services to perform the task, Google also processes that content.
