Introducing Gemini 3.8 Flash and 3.8 Flash Cyber

Google launched Gemini 3.8 Flash and 3.8 Flash Cyber on September 2, 2026, the third Flash release in six weeks. The base model matches or exceeds larger frontier models on software engineering and reasoning benchmarks, including a 54.9% score on HLE-Verified, at the same price as its predecessor: $0.75 per million input tokens and $3.75 per million output tokens. The Cyber variant hits 47.2% pass@1 on CWE-Bench patching, found a critical Google Cloud vulnerability in under 2 hours versus the typical months-long timeline, and produced 2.6x more correct Chrome patches than leading commercial models. Access to 3.8 Flash Cyber is restricted to vetted government and critical infrastructure defenders through Google's new Fairwind Program. Both models include prompt injection hardening and CBRN safeguards aligned with Google's Frontier Safety Framework.
