USC Study: Frontier AI Models Fail Social Safety Over 27% of the Time
A new study from the University of Southern California (USC) finds that every tested frontier AI model violates social-interaction safety guidelines more than 27% of the time. The research introduces EUDAIMONIA, a benchmark that evaluates undesirable dynamics in human-AI conversations, such as flattery, emotional attachment, relationship replacement, and failure to disclose AI identity. The study analyzed 969 user inputs and over 3,100 violation checks across models from OpenAI, Anthropic, Google, xAI, DeepSeek, and Alibaba using real conversations from the WildChat dataset. GPT-5.5 had the lowest violation rate (25.0% on real-world prompts), while GPT-4o Mini had the highest (43.3%). The authors argue that AI safety evaluations should measure social behavior alongside reasoning and traditional safety metrics, as models that are factually accurate can still cause harm by encouraging harmful intimacy or dependence. The findings come amid growing legal scrutiny, including lawsuits against OpenAI and Google over chatbot-related harms, and concerns about AI deception and emotional dependency.
