Gemini Decision 1 is now available on AI Gateway, a unified platform for accessing and managing AI models. This multimodal decision model can process text, images, audio, video, and PDF documents, providing Boolean probabilities, choices, and scores. It can be used for tasks such as routing requests, checking policies, filtering agent tools, and ranking results without generating output tokens. The model is accessible through the AI SDK, TypeSafe-compatible API, or Decisions API, with varying input support depending on the API used. AI Gateway tracks usage and cost, including decision calls, and provides a centralized way to manage models.
