Holistic Safety and Responsibility Evaluations of Advanced AI Models
(2404.14068)Abstract
Safety and responsibility evaluations of advanced AI models are a critical but developing field of research and practice. In the development of Google DeepMind's advanced AI models, we innovated on and applied a broad set of approaches to safety evaluation. In this report, we summarise and share elements of our evolving approach as well as lessons learned for a broad audience. Key lessons learned include: First, theoretical underpinnings and frameworks are invaluable to organise the breadth of risk domains, modalities, forms, metrics, and goals. Second, theory and practice of safety evaluation development each benefit from collaboration to clarify goals, methods and challenges, and facilitate the transfer of insights between different stakeholders and disciplines. Third, similar key methods, lessons, and institutions apply across the range of concerns in responsibility and safety - including established and emerging harms. For this reason it is important that a wide range of actors working on safety evaluation and safety research communities work together to develop, refine and implement novel evaluation approaches and best practices, rather than operating in silos. The report concludes with outlining the clear need to rapidly advance the science of evaluations, to integrate new evaluations into the development and governance of AI, to establish scientifically-grounded norms and standards, and to promote a robust evaluation ecosystem.

Holistic Safety Evaluation of Generative AI at Google DeepMind
Introduction to DeepMind's Safety Evaluation Approach
Safety evaluation is essential for advancing the responsible development and deployment of generative AI technologies. Google DeepMind's paper delineates a comprehensive safety evaluation framework that integrates diverse risk areas, methodologies, and perspectives. This framework emphasizes collaboration across various safety communities and outlines the processes implemented from initial risk identification to post-deployment monitoring. Key goals include sharing insights to boost the broader ecosystem for AI safety and influencing public discourse on these critical issues.
Foresight and Risk Prioritization Methods
DeepMind employs a dual strategy in its safety evaluations—foresight and real-time incident monitoring. This method not only anticipates potential harms but also engages in continuous validation of these forecasts against real-world applications of AI. Notably, the AI safety team emphasizes the need for interdisciplinary coordination to precisely understand both technological capabilities and their sociotechnical impacts. This involves rigorous prioritization of risks and a structured internal framework guiding the assessment of their proprietary models, such as Gemini Ultra.
Evaluation Approach and Methodological Innovations
The safety evaluation process at DeepMind is multifaceted, focusing on both detection of immediate model outputs that could result in harm and longer-term research into the impact of AI systems in diverse contexts. This includes exploring novel methodological approaches such as leveraging more human-centric methods and system-level evaluations that encompass broader societal impacts. The strategic incorporation of dynamic evaluation methods like red teaming and continuous human-interaction testing forms a critical part of refining this process.
Addressing Evaluation Gaps
Despite the advancements in safety evaluation techniques, significant gaps remain, particularly for models that operate across different modalities and languages. DeepMind's approach involves enhancing current evaluation standards to cover these emerging needs. This is crucial as the field moves towards more general-purpose AI systems where traditional text-based evaluation frameworks may no longer suffice.
Emergence of a Robust Evaluation Ecosystem
The paper underscores the growing intricacy and necessity of fostering a sturdy AI evaluation ecosystem that involves academics, industry professionals, and government bodies. The interplay between internal evaluation processes and external validation by third-party entities is highlighted as vital for a comprehensive safety assessment. This ecosystem also necessitates standardized methodologies to ensure consistency and reliability across various evaluation efforts.
Standardization and Community Engagement Needs
The discussion extends into the need for standardizing safety evaluation practices. The establishment of common standards will crucially support the scaling of safety evaluations alongside the rapid development of AI technologies. DeepMind advocates for active collaboration within the AI safety community to harmonize practices and share insights, which is imperative for developing internationally recognized and robust safety evaluation standards.
Conclusion on Safety Evaluation Practices
The paper concludes with a reaffirmation of the importance of principled and scientifically robust safety evaluations in AI development. It calls for ongoing improvements in evaluation practices to keep pace with the continuously advancing AI landscape. The commitment to refining these evaluations, informed by both emerging risks and technological capabilities, is positioned as essential for the responsible governance and deployment of AI systems.
DeepMind’s detailed exploration of AI safety evaluations reflects a proactive and deeply integrated approach to understanding and mitigating the potential risks associated with generative AI systems. As the field evolves, so too will the methodologies and frameworks for ensuring these technologies are beneficial and safe for widespread use.
