Agentic video understanding is a new Gemini processing mode (3.7 Flash, 3.6 Flash, 3.5 Flash-Lite) that lets the model decide what to watch, at what speed, and through which modality, instead of a fixed frame rate. Cuts tokens by up to 88%, cost by up to 66%, boosts accuracy up to 7%, biggest wins on long-form video. Live now via Gemini API in AI Studio and Gemini Enterprise Agent Platform, just set processing to "agentic," standard pricing, no extra fee.
