In this AWS re:Invent 2023 session, Michael Kearns and Peter Hallinan discuss the challenges and opportunities of responsible AI in the generative era. They explore the evolving science behind responsible AI, focusing on issues like fairness, privacy, and safety in large language models. The speakers highlight the complexities of defining and enforcing responsible AI practices in generative models compared to traditional AI applications. They also discuss AWS's approach to operationalizing responsible AI principles across the ML lifecycle and emphasize the importance of narrow use case definitions, risk-based approaches, and stakeholder engagement in developing and deploying generative AI solutions responsibly.
