## Definition

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](https://blog.google/innovation-and-ai/models-and-research/gemini-models/gemini-3-5/) 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.

## Analogy

Think of it as the jet engine in economy class — more thrust than the old first-class seat, at a third of the price.

## Why it's emerging now

Google shipped Gemini 3.5 Flash at I/O 2026 on May 19 as its first model to beat its own Pro tier on agentic benchmarks while running 4x faster. It is now the live default for the Gemini app and Google Search globally, and immediately available via API and GitHub Copilot.
