TL;DR: Gemini 3.8 Flash in 30 seconds
Gemini 3.8 Flash landed on September 2, 2026, three weeks after 3.7 Flash. That is the third Flash release in three months.
Price did not move: $0.75 input, $3.75 output per million tokens. The promo ends December 31, 2026, then it doubles.
A second model shipped alongside it: Gemini 3.8 Flash Cyber, tuned for vulnerability discovery and locked behind the new Fairwind Program.
The benchmark table is split. It tops the chart on finance, legal, long video and chart reasoning, and it trails Claude Opus 5 badly on long horizon terminal and computer use work.
