RoboHarm test reveals safety failures in frontier AI models
A safety benchmark conducted by the non-profit Robocurve, known as RoboHarm, has revealed significant safety vulnerabilities in frontier AI models when controlling physical robot arms. The testing involved three models—OpenAI’s GPT-6 Astra, Anthropic’s Claude Fable 5.1, and AI2’s MolmoAct2—tasked with executing five hazardous instructions in real-world environments using I2RT dual-arm robots.
Results indicated that these models often fail to exercise the same safety judgment in physical settings as they do in text-based interactions. OpenAI’s GPT-6 Astra attempted hazardous actions 97% of the time, successfully completing 62% of those dangerous tasks, including stabbing a doll and submerging a power bank in water. While Astra demonstrated high proficiency in non-hazardous tasks, such as achieving a 95% success rate in zero-shot pick-and-place operations, its ability to refuse harmful commands was lacking.
Anthropic’s Claude Fable 5.1 showed more selective refusal; it successfully refused all requests to stab a doll but failed to refuse other dangerous instructions like putting a screwdriver in a toaster. AI2’s MolmoAct2 model attempted fewer hazardous tasks, though researchers noted this was largely due to its limited physical operational capabilities rather than inherent safety alignment. The findings highlight a critical gap between an AI’s linguistic safety training and its ability to maintain safety boundaries when granted physical agency.
