OpenAI Announces Priorities and Principles for Third-Party Assessments of Frontier AI Safety

On September 22, 2026, OpenAI emphasized the importance of third-party assessments to strengthen safety responsibilities for Frontier AI models and announced specific operational principles. This document focuses on independent assessment organizations from the private and non-profit sectors gaining deep access during the training, evaluation, and deployment stages to verify the evidence validity of safety cases and safety claims.

Purpose and Scope of Assessments

Third-party assessments check whether model capabilities and safeguards function appropriately under real-world conditions and confirm the adequacy of risk measurements. Assessments are launch-agnostic and can take weeks to months, requiring expertise in various fields such as alignment, control methods, cybersecurity, and biological misuse. In particular, the adequacy of thresholds in the Preparedness Framework and independent investigations into serious misalignment incidents are cited as priorities.

Four Priority Areas and Principles

To ensure the reliability and effectiveness of assessments, OpenAI has presented the following priority areas:

• Gap Assessment of Misalignment Monitors: Identifying critical flaws in monitoring systems that could lead to loss of control or severe misalignment in internal and external deployments.
• Capability and Alignment Evaluations: Conducting alignment evaluations for Preparedness risk categories (chemical/biological risks, cybersecurity, AI self-improvement) and serious misalignment risks.
• Independent Incident Investigations: Conducting investigations into misalignment incidents through independent third parties in specific situations, such as the OpenAI Hugging Face incident.
• Technical Partnerships: Identifying weaknesses in safeguards and accelerating the development of evaluation methods and standards to establish the technical foundation for future public policy.

Operational principles emphasize clear scope and prior agreement (pre-registering scope and safety claims before assessment), actionable outcomes (identifying specific gaps and granting remediation periods), as well as conflict of interest prevention, security, and responsible disclosure.

Future Plans and Limitations

OpenAI acknowledges that a single third party cannot cover all Frontier Safety questions and plans to expand the ecosystem by supporting the establishment of international standards and collaborating with a diverse community of independent evaluators. Currently, OpenAI is in discussions with multiple third parties regarding proposals that align with the aforementioned priority areas.
