Introducing Gemini 3.8 Flash and 3.8 Flash Cyber
Google, Wednesday, September 2nd, 2026
Google ships Gemini 3.8 Flash plus a cybersecurity-specialized Flash Cyber variant at 3.7's speed and cost.
Google introduced Gemini 3.8, its third Flash release in six weeks, describing it as the company's best reasoning and coding model yet while keeping the speed and low cost of 3.7 Flash.
Two variants ship: Gemini 3.8 Flash, positioned as the most intelligent workhorse model with significant software engineering gains over 3.7, and Gemini 3.8 Flash Cyber, tuned for cybersecurity work.
Google frames both as built for agentic workflows rather than single-turn chat. The release builds directly on momentum from 3.7 Flash three weeks earlier.
