Summary:
L’Institut de sécurité de l’IA (AISI), en collaboration avec le Centre pour la gouvernance de l’IA, a publié un document présentant un modèle de cas de sécurité destiné à évaluer la sécurité des systèmes d’IA actuels et futurs. Ce développement est important car il fournit un cadre systématique pour évaluer la sécurité de l’IA, garantissant la responsabilité dans les industries à enjeux élevés où les technologies d’IA sont déployées. Les points clés incluent l’utilisation d’une notation structurée pour les revendications, les arguments et les preuves afin de soutenir les arguments d’incapacité, en se concentrant initialement sur le risque cybernétique, et en mettant en évidence les désaccords ou les lacunes potentielles dans l’évaluation. Le modèle souligne des méthodes pratiques pour déterminer l’incapacité d’un système à causer des dommages en utilisant des métriques de sécurité robustes, tout en reconnaissant des limitations pour les systèmes de plus grande capacité. Les travaux futurs de l’AISI exploreront des arguments supplémentaires pour les systèmes de capacités moyenne et élevée, y compris des garanties contre les abus, ainsi que la contribution au développement de seuils internationaux comme discuté dans la Déclaration ministérielle de Séoul.

Safety cases are systematic and structured arguments that demonstrate the safety of a system within a specific context, providing a practical tool to manage AI risks. The AI Safety Institute (AISI), in collaboration with the Centre for the Governance of AI, has introduced a new template aimed at applying safety cases to AI technologies, particularly frontier AI systems. Such efforts are inspired by their successful application in high-stakes industries like aviation, healthcare, and nuclear energy. Google DeepMind and Anthropic, for instance, have already explored safety case methodologies to strengthen their respective safety frameworks.
Legally, safety cases hold significant potential to bolster compliance with AI-related regulatory frameworks such as the EU’s Artificial Intelligence Act (AIA) and the UK’s pro-innovation regulatory approach outlined in its AI White Paper. By enabling developers to clearly articulate the context-specific safety of their AI systems, safety cases could smooth compliance and demonstrate adherence to principles of accountability and transparency embedded in these legal structures. Furthermore, they align with international agreements such as the Seoul Ministerial Statement, which calls for collaborative development of AI safety thresholds.
Ethically, safety cases address the moral responsibility of developers to mitigate harm. For instance, they push organizations to explicitly demonstrate systems’ limitations, thereby reducing risks associated with cyber threats or misuse. AISI’s inclusion of ‘inability arguments,’ which focus on asserting that AI systems do not possess capabilities that would render them hazardous, encourages ethical considerations such as proactive harm prevention and equitable risk management across diverse application scenarios.
Industrially, the adoption of safety cases could signal a paradigm shift in AI development. Developers would benefit from a robust but flexible framework to assess and communicate safety risks, ultimately fostering consumer trust and preempting liabilities. AISI’s safety case template also highlights the importance of integrating sociotechnical factors, such as organizational culture and employee training, to address complex risks more holistically. When applied to real-world problems, such as mitigating AI-related cybersecurity risks, safety cases offer structured arguments using Claims, Arguments, and Evidence notation. This layered approach consists of breaking down risks into manageable models like threat actors and harm vectors and linking these to tangible tests such as capture-the-flag tasks.
An illustrative example lies in autonomous vehicle safety. In this sector, safety cases have successfully built trust by demonstrating clear risk quantification and mitigation strategies. Similarly, AISI’s inability arguments for frontier AI cater to scalable safety assurance. For current systems with low capabilities, the framework effectively substantiates the argument that these systems are safe due to their inability to cause harm—a premise built on rigorous capability evaluations and adherence to best practices.
However, challenges remain for higher-capability systems. As such systems approach thresholds that may signify unacceptable safety risks, the inability argument diminishes in sufficiency. To address this, AISI suggests enhancing safety cases for advanced AI by incorporating complex safeguards against misuse—a critical action for systems that may manipulate evaluations or evade safeguards. This evolving approach underscores the need for dynamic regulatory practices and ongoing research to refine AI safety strategies further.
As AISI continues to advance work on medium- and high-capability systems, it is clear that their framework presents a credible starting point for improving AI safety governance. The Institute calls on organizations to adopt and pilot these templates, paving the way for safety cases as a standard tool in ensuring AI development aligns with societal and ethical expectations.
