About Google
Google's Gemini models are natively multimodal — most accept text, images, audio and video input — with 1M-token context windows across the range. The Flash line now ships on a roughly monthly cadence (3.6, 3.7, 3.8 Flash between July and September 2026) at the same introductory price, competing on price-performance and speed rather than peak capability.
