The Gemini Decisions API, powered by the Gemini Decision 1 model, has been introduced by Google, enabling fast and calibrated multimodal decisions for Google apps. This API allows for the evaluation of up to 1,000 yes/no, choice, and rubric-scoring questions in a single pass, supporting various formats such as text, images, audio, video, and PDFs. It provides confidence scores for multiple questions, making it a cost-effective solution for routing queries, grading content, or checking policy rules, and is available for access through the Google AI Studio with accompanying documentation.
