Google hasn’t released a frontier-level Gemini Pro AI model since early 2026, but it sure loves rolling out new Gemini Flash variants. Today, Google is announcing its third Flash model release in just six weeks, making it more likely that we’ll never see the promised Gemini 3.5 Pro. But no matter, says Google, because Gemini 3.8 Flash is its best reasoning and coding model yet.
Gemini 3.8 Flash comes in two variations. There’s the standard Flash, which Google describes as a “workhorse” model that’s good for anything from agentic tasks to software development. Then we have Gemini 3.8 Flash Cyber, which runs on the same foundations but has been tuned for vulnerability detection and mitigation.
For developers, Google has the same pitch as it did for the 3.7 Flash release just a couple of weeks ago. API access to the model is available at an “introductory rate” through the end of the year: $0.75 per million input tokens and $3.75 per million output tokens. The regular price will be $1.50 / $7.50, but it’s likely there will be new models available long before the price changes. Google probably sees the lower prices as a necessity given that other AI labs have recently dropped token pricing to keep increasingly wary businesses engaged with AI tools.
Google has offered its usual raft of benchmark numbers, which appear to show Gemini 3.8 Flash competing with (or even beating) larger and more expensive models. The numbers show a marginal improvement over Gemini 3.7 Flash in most tests, but the gains are larger in coding evaluations.
Gemini 3.8 Flash is now at the top of the DeepSWE leaderboard, which measures a model’s ability to solve complex software engineering problems, and it does so at a lower cost (at the current discounted rate). Google reportedly delayed the release of Gemini 3.5 Pro when its coding performance couldn’t match other models, but if these numbers reflect reality, even Google’s new Flash models are competing with the market leaders.
Computer use has been a struggle for Google’s models. While Gemini 3.8 Flash is an improvement over 3.7 Flash in the OSWorld-2.0 test of agentic computer use, it’s still far behind the market leader Claude Opus. In fairness, GPT isn’t great in this test, either.
Gemini 3.8 Flash Cyber, which replaces the 3.5 version, isn’t something most of us will ever need to think about, but these models are increasingly important in niche fields. Google claims that the new cybersecurity model has demonstrated a substantial improvement over its previous models with internal testing. Gemini 3.8 Flash Cyber reportedly identified more vulnerabilities and issued working patches more often. The Chrome security team apparently saw a 2.6x increase in patch accuracy with the new model. The Cloud team reports that 3.8 Flash Cyber found a critical vulnerability in just two hours. Google also has statements from partners like Wiz and Palo Alto Networks attesting to the power of Gemini 3.8 Flash Cyber.
Gemini 3.8 Flash will be available across the Google ecosystem starting today, but Gemini 3.8 Flash Cyber is currently limited to trusted testers and governments. Like the past Flash release, you’ll need a Pro or Ultra subscription to access Gemini 3.8 Flash in the Gemini app, but you can always visit AI Studio if you want to tinker with it for free.
