Google Releases Gemini 3.8 Flash and Cyber Variant

Google just released a new Gemini 3.8 Flash model for Google AI Pro and Ultra subscribers today, three weeks after the release of Gemini 3.7 Flash. A new Gemini 3.8 Flash Cyber model, optimized for cybersecurity tasks, is also available today via Google Fairwind, the company’s new limited-access program for governments and trusted partners.

Since the release of Gemini 3.6 Flash in late July, Google has been shipping new Flash models every three weeks. These lightweight multimodal AI models are optimized for multi-step reasoning and agentic workflows, and this 3-week release cycle also gives Google more time to ship its much-anticipated Gemini 3.5 Pro model, which the company announced at its I/O conference in May 2026.

Google described Gemini 3.8 Flash as its “most intelligent workhorse model, delivering significant improvements from 3.7 Flash across software engineering, agentic tasks, and critical, multi-step reasoning in specialized domains.” Google also said Gemini 3.8 Flash is “often approaching the performance of higher-cost frontier” models, all while coming with better protections against prompt injection attacks.

Speaking of costs, Gemini 3.8 Flash matches the introductory price of Gemini 3.7 Flash for developer and enterprise users, with a $0.75 per million input tokens and $3.75 per million output tokens pricing structure. For consumers, the new model is available via the Google Gemini app, AI Mode in Google Search, and Gemini in Google Sheets for users with a Google AI Pro or Ultra subscription.

Gemini 3.8 Flash Cyber, Google’s latest cybersecurity model, is better at discovering vulnerabilities on its own, Google said today. “It surpasses both 3.5 Flash Cyber as well as significantly larger frontier models,” the company said, adding that “the Chrome Security team found that 3.8 Flash Cyber produced 2.6 times more correct patches to vulnerabilities in Chrome than the best commercial models that are much larger.”

As I mentioned earlier, access to Gemini 3.8 Flash Cyber will be provided via Google’s new Fairwind Program, which will be opened to Governments and national cyber authorities, Critical infrastructure operators, and Core technology platforms. Google said today that it will “vet all applicants to make sure they have a proven track record of ethical operations and research.”
