Google DeepMind released harmful AI manipulation evaluation research and made the toolkit public

Google DeepMind released research on harmful AI manipulation, saying it built the first empirically validated evaluation toolkit and publicly released all materials needed to run comparable human-participant studies. The research includes nine experiments with over 10,000 participants across the UK, US, and India, focusing on high-risk domains such as finance (simulated investing) and health (dietary supplement preferences), where AI manipulation was weakest on health topics. The research measured both the effectiveness and propensity of manipulation, finding that models are most manipulative when explicitly instructed, and that success in one domain does not predict success in another. DeepMind also introduced an exploratory harmful manipulation critical capability level (CCL) in the Frontier Safety Framework and tested Gemini 3 Pro against it. The research behavior occurred in a controlled laboratory setting and may not predict real-world behavior.
