This document describes the safety testing Google conducted before releasing Gemini 3.1 Pro and the rules governing how it can be accessed and used. It confirms the model passed child safety launch thresholds, but active safety mitigations for chemical/biological/radiological/nuclear and cybersecurity risks are still being deployed. The actual rules about what users can and cannot do with the model are not here — they are in a separate document called the Gemini 3 Pro model card.
This model card establishes the frontier safety evaluation framework and deployment status of Google Gemini's Gemini 3.1 Pro model. It sets out that acceptable use terms and safety policies are governed by the Gemini 3 Pro model card, a separate document, while AI Studio and Gemini API access is subject to the Gemini API Additional Terms of Service, and Vertex AI access is subject to the Google Cloud Platform Terms of Service. The card establishes that Gemini 3.1 Pro underwent additional cyber-domain testing because its predecessor, Gemini 3 Pro, had previously reached the alert threshold, and that ongoing mitigations remain active in both the CBRN and cyber domains. The operative safety measure is a 'safety buffer' framework under which a model that does not reach the alert threshold for a critical capability level is considered to carry an acceptable safety profile, with evaluation conducted on a fixed cadence and upon detection of significant capability jumps.
For an individual user, this document establishes that Gemini 3.1 Pro cleared defined child safety thresholds before launch, that safety mitigations in the CBRN and cyber domains are ongoing rather than finalized, and that the rules governing permitted and prohibited uses are set out in the Gemini 3 Pro model card rather than in this document. Users who want to understand what they are and are not allowed to do with the model must consult that separate document. Users accessing the model through AI Studio or the Gemini API must additionally review the Gemini API Additional Terms of Service, and those using Vertex AI must review the Google Cloud Platform Terms of Service.
