Google has launched Gemini 3.8 Flash and Gemini 3.8 Flash Cyber, expanding its fast and low-cost artificial intelligence lineup with specialized upgrades for autonomous agent workflows and automated cybersecurity defense. According to a company announcement on September 2, the standard 3.8 Flash model arrives as a general-purpose workhorse designed to improve software engineering and multi-step reasoning while maintaining the pricing structure of its predecessor.
Gemini 3.8 Flash Pricing and Performance
Google keeps the pricing for Gemini 3.8 Flash identical to the previous generation at $0.75 per million input tokens and $3.75 per million output tokens, according to the official company statement. Despite retaining this low cost, the model delivers performance that surpasses several higher-priced frontier systems. According to Google’s release notes, 3.8 Flash outperforms Cloud Opus 5 and GPT-5.6 Sol in financial analysis tasks, complex legal workflows, long-video comprehension, and multidisciplinary expert reasoning.
The updated model builds directly on the momentum of Gemini 3.7 Flash, which debuted just three weeks prior as part of a rapid release cycle that has seen three Flash introductions in six weeks. The shared foundational intelligence relies on long-running agentic loops that recursively evaluate and refine outputs. The model is immediately available across multiple developer environments and productivity apps, including Google AI Studio, Android Studio, Google Antigravity, Gemini Enterprise, and for subscribers using Google AI Pro and Ultra in the Gemini app, the AI Mode in Google Search, and Gemini in Google Sheets, as reported by Portaltic and ADSLZone.
Gemini 3.8 Flash Cyber and the Fairwind Program
Alongside the standard workhorse, Google introduced Gemini 3.8 Flash Cyber, positioned as its most advanced ciberdefense model to date. According to the company’s technical disclosures, the model detects system vulnerabilities and automatically generates code patches by leveraging the low latency and cost profile of the Flash architecture.
In industry benchmark testing on the CyberGym tool—which measures vulnerability discovery across complex codebases spanning 20 programming languages—Gemini 3.8 Flash Cyber achieved a success rate exceeding 70 percent, performing slightly above GPT-5.6 Sol and Claude Mythos 5, according to Portaltic. Google is releasing the cyber defense model under a controlled rollout via its new Fairwind Program. This initiative mirrors similar restricted access programs deployed by competitors, such as Daybreak by OpenAI, Glasswing by Anthropic, and Perception by Microsoft, making specialized safety tools available to trusted defenders.
Internally, Google has already deployed 3.8 Flash Cyber to secure its own infrastructure. According to the company’s corporate communications, the model identified a critical fundamental vulnerability in Google Cloud in under two hours and generated 2.6 times more correct patches for Chrome software flaws than larger commercial models.
