OpenAI and Anthropic Launch Joint Third-Party Safety Auditing Pilot for Frontier Models

OpenAI and Anthropic have jointly announced a pilot program inviting independent auditors to conduct structured safety evaluations of their frontier models using a shared evaluation framework. The program, developed with NIST and the UK AI Safety Institute, covers capability assessments in biosecurity, cybersecurity, and persuasion. Participating auditors sign disclosure agreements but may publish aggregate findings without model-specific details.
