Gemini Decision 1 from Google is now available on AI Gateway. The multimodal decision model works with text, images, audio, video, and PDF documents, returning Boolean probabilities, choices, and scores. Use it to route requests, check policies, filter agent tools, or rank results without generating output tokens.
Use google/gemini-decision-1 with the AI SDK, TypeSafe-compatible API, or Decisions API.
PDF, audio, and video inputs are supported through AI SDK 7. The TypeSafe-compatible and Decisions APIs support text and image inputs.
AI Gateway provides a unified way to access models and track usage and cost. Decision calls appear in logs and count toward budgets alongside other model requests.
See the decision documentation for Choice, Score, and Boolean questions. To pick a decision model, browse the available models or read our decision model guides.
