Gemini 3.8 Flash replaced Gemini 3.7 Flash about three weeks after it, at the same introductory price ($0.75 input / $3.75 output per million tokens, rising to $1.50/$7.50 from 2027-01-01). Google reports clear gains on coding and agent benchmarks (Terminal-Bench 2.1 around 90 vs 81.6 for 3.7 Flash), though independent tests found it uses roughly 30% more output tokens per task, so the real cost per task is higher than the list price suggests. It accepts text and images with a 1M-token context window. A restricted Gemini 3.8 Flash Cyber variant exists for vetted security partners.
