  To understand the risks posed by a new AI system, we must understand what it
can and cannot do. Building on prior work, we introduce a programme of new
"dangerous capability" evaluations and pilot them on Gemini 1.0 models. Our
evaluations cover four areas: (1) persuasion and deception; (2) cyber-security;
(3) self-proliferation; and (4) self-reasoning. We do not find evidence of
strong dangerous capabilities in the models we evaluated, but we flag early
warning signs. Our goal is to help advance a rigorous science of dangerous
capability evaluation, in preparation for future models.
