Gemini 3.5 Flash
Gemini 3.5 Flash is Google's frontier multimodal AI model that combines flagship-tier reasoning with Flash-class speed, designed to execute multi-step agentic workflows, complex coding tasks, and long-horizon document reasoning without sacrificing latency. It supports text, image, audio, and video inputs with a 1-million-token context window.
Announced and released on May 19, 2026 at Google I/O 2026, it is the first model in the Gemini 3.5 family. Priced at $1.50/$9.00 per million input/output tokens, it outperforms Gemini 3.1 Pro on agentic benchmarks (Terminal-Bench 2.1: 76.2%, MCP Atlas: 83.6%) while running four times faster in output token throughput.
Think of it as the jet engine in economy class — more thrust than the old first-class seat, at a third of the price.
