Abstract:
Large language model (LLM) Agents are powerful tools for completing complex tasks but remain underexplored in their ability to self-improve through feedback, adaptation, and exploration. In this talk, I present key advances in these three directions. First, I show that by drawing an analogy between optimization and interactive learning, feedback emerges as a powerful driver of iterative improvement for LLM agents. In particular, I highlight how directional feedback enables stable and efficient performance across a wide range of optimization tasks. Second, I introduce a novel optimization framework, "Optimization with Trace Oracle (OPTO),” that leverages execution traces and rich feedback to optimize LLM agents with complex workflows, akin to how AutoDiff enables differentiable optimization. Finally, I investigate LLMs' exploration capabilities in uncertain decision-making scenarios, proposing algorithm-guided methods that enable
smaller models (Gemini-1.5 Flash) to outperform larger ones (Gemini-1.5 Pro) in exploratory efficiency. Together, these insights outline a foundation for LLM agents that can learn, adapt, and explore autonomously, paving the way for the next generation of interactive AI systems.

![Open AI: considering the ethical upsides and downsides of Open AI development
Abstract:
In this talk, I will discuss the ethical upsides and downsides of releasing AI openly.
I will first present our FAccT’22 paper [1], where we interview contributors to an open source Deepfake tool about their sense of responsibility and agency to prevent harm. We show that open source licenses and norms combine with notions of technological inevitability and neutrality to lead contributors to disavow responsibility for harmful ways their tool is used.
I will then broaden to discuss other work examining AI openness, situated in the context of “Open”AI’s U-turn on openness. I will discuss benefits of AI openness, such as supporting open science, and enabling wider scrutiny for harms such as bias, and downsides, such as enabling the proliferation of powerful tools which can be used to harm.
I will then conclude by enumerating and advocating for a variety of “middle ground” approaches to AI openness, including methods of norm setting, ethical licenses, release gating, or hard technical restrictions, before opening up discussion for other ways of tackling this thorny problem.
