European policymakers criticized AI company Anthropic for its representation during a hearing on the risks of advanced AI capabilities, according to Politico EU. Lawmakers had requested the presence of Anthropic's head of public policy, but the company sent a technical employee, Donny Greenberg, who joined the company in April. The hearing, the first of its kind in Brussels regarding advanced AI risks, focused on Anthropic's cyber-capable models, Mythos and Fable, which are capable of identifying and exploiting software vulnerabilities. European institutions have sought access to these models due to concerns about potential risks to critical infrastructure. Lawmakers voiced frustration that Greenberg, identifying himself as a technical expert, might be unable to address policy-related questions, exacerbated by the perception that he was reading his responses, leading to questions about whether he was relying on AI. Anthropic stated it is working with the EU's AI Office and cybersecurity agency, ENISA, to enhance cyber resilience, acknowledging AI as a dual-use tool.
