Gemini Decision 1

Gemini Decision 1 is Google's AI model for quick, bounded decisions rather than open-ended writing, and it powers the Gemini Decisions API that developers can plug into their own products through Google AI Studio. Instead of generating an answer word by word, it scores a set of candidate options in a single pass and returns probabilities and confidence scores. It understands text, images, audio, video, and PDFs together, and it can handle many separate questions about one input at once. The company says this makes it fast and cost-effective for picking a tool, routing a query, checking a policy rule, or grading content. Because it only chooses among options you supply, it does not write text, so it fits classification-style steps inside a larger system rather than conversation.
