Gemini 3.8 Flash rolling out three weeks after last release
After the last model release three weeks ago, Google today is rolling out Gemini 3.8 Flash. This marks the third Flash update in three months.
…our most intelligent workhorse model, delivering significant improvements from 3.7 Flash across software engineering, agentic tasks, and critical, multi-step reasoning in specialized domains.
Gemini 3.8 Flash “delivers substantial gains” over its predecessor in various benchmarks, with Google also noting how it is “often approaching the performance of higher-cost frontier models.”
Google says these “performance gains stem from a core design choice: 3.8 Flash works harder.”
On complex tasks, it exhibits greater diligence — executing extra reasoning steps, and calling tools iteratively. At times, the model might use more tokens to maximize performance, especially at higher effort levels.
Similar to the previous model, Gemini 3.8 Flash’s knowledge cutoff date is March 2026 “for some domains while in others [users] may experience the model’s knowledge is limited to January 2025.”
Google is once again offering an introductory price of $0.75/1M input tokens and $3.75/1M output tokens until December 31.
Gemini 3.8 Flash is already live in the Gemini app for Google AI Pro and Ultra subscribers, AI Mode, and Gemini in Google Sheets. It’s also available for developers in Google Antigravity, AI Studio, and the Gemini API.
Google today also announced Gemini 3.8 Flash Cyber (replacing 3.5) for trusted testers — via a new Fairwind Program — with “frontier-level performance in autonomous vulnerability discovery.”
