Gemini 3.8 Flash

We continue to improve our internal evaluations, including refining automated evaluations to reduce false positives and negatives, as well as update query sets to ensure balance and maintain a high standard of results. The performance results reported below are computed with improved evaluations and thus are not directly comparable with performance results found in previous Gemini model cards. We expect variation in our automated safety evaluations results, which is why we review flagged content to check for egregious or dangerous material. Our manual review confirmed losses were overwhelmingly either a) false positives or b) not egregious. Human Red Teaming Results We conduct manual red teaming by specialist teams who sit outside of the model development team. High-level findings are fed back to the model team. For child safety evaluations, Gemini 3.8 Flash satisfied required launch thresholds, which were developed by expert teams to protect children online and meet Google’s commitments to child safety across our models and Google products. For content safety policies generally, including child safety, we saw similar or improved safety performance compared to Gemini 3.7 Flash. Additionally, the scope of red teaming covered potential issues outside of our strict policies, compared performance to Gemini 3.1 Pro, and found no egregious concerns. Frontier Safety Assessment Gemini 3.8 Flash is part of the Gemini 3 series of models. We evaluated Gemini 3.7 Flash as outlined in our latest Frontier Safety Framework (April-2026), and found that it did not reach any Tracked or Critical Capability Levels (T/CCLs). Our assessments have shown that Gemini 3.8 Flash does not have meaningful new capabilities or material increases in performance with respect to the domains outlined in our Frontier Safety Framework compared to Gemini 3.7 Flash; therefore, based on Gemini 3.7 Flash results, we are confident that Gemini 3.8 Flash is also unlikely to reach any T/CCLs.
