The AI Evaluator Forum (AEF) welcomes recent statements regarding the importance of embedded independent experts to verify AI safety and security claims. This is a first step towards trustworthy oversight of frontier AI. No single evaluator can do this work alone. A vibrant ecosystem of independent evaluators from distinct backgrounds can offer a range of expertise and methodology, help to ensure rigor, and avoid a single point of failure. The Forum exists to strengthen this ecosystem. Realizing the benefits of third-party evaluations also requires independence, access, and transparency. AEF brings evaluators together to address these questions. Our first standard, AEF-1: Minimum Operating Conditions for Independent Third-Party AI Evaluations, envisions a minimum floor for access, managing conflicts of interest, funding relationships, recusal requirements, and transparency of evaluation terms. Read more here: The long-term success of third-party evaluation relies on standards and frameworks. AEF is committed to developing these with its members and collaborators. We welcome engagement from organizations committed to rigorous, independent work. Learn more about AEF, express interest in joining, and raise questions for us here:
