Gemini 3 Flash, released December 17, 2025, brought Gemini 3 Pro’s reasoning quality down to Flash-tier latency and cost. It carries a 1 million token input context window and handles multimodal input across text, image, audio, and video, with pricing starting at $0.50 per million input tokens and $3.00 per million output tokens. Google positioned it as the default model for the Gemini app and API workloads that don’t need Pro-level depth, and it remained the workhorse Flash tier until Gemini 3.5 Flash replaced it in May 2026.
