Event Summary
Google introduced Gemini 3.8 Flash and Gemini 3.8 Flash Cyber on September 2, 2026. The standard model is available through Google products and APIs at introductory pricing; the Cyber model is restricted to trusted defenders through the Fairwind Program. Google reported coding, vulnerability-discovery, patching, and Chrome security results, which are not independent replications of the vendor's full evaluation program.
Context & Narrative
Google says 3.8 Flash improves long-horizon software engineering and that its higher effort settings can consume more tokens. For Flash Cyber, Google reports a 47.2% pass@1 on CWE-Bench and internal Chrome outcomes, while saying the model is distributed only to trusted defenders because of more permissive cyber mitigations. EpochArc records the release and access model as facts and labels all performance and operational results as Google's reports.
