Roberta Raileanu of Google DeepMind at RAAIS 2026
Summary
Roberta Raileanu, a Senior Staff Research Scientist at Google DeepMind and Adjunct Professor at UCL, focuses her research on enabling frontier AI models to perform long-horizon tasks, use tools, recover from errors, and continuously improve through interaction in complex environments. Her early work in reinforcement learning addressed exploration challenges, leading to papers like "RIDE" (ICLR 2020) and "AMIGo" (ICLR 2021). At Meta, she led the Tool Use team for Llama 3, contributing to products used by hundreds of millions and co-authoring "Toolformer" (2023), which demonstrated models learning to use external APIs with minimal supervision. Currently, at DeepMind, she leads the Open-Endedness team, aiming for systems that autonomously discover novel artifacts and adapt to shifting real-world distributions, avoiding the need for constant human task redefinition. She also contributed to "MLGym" (2025), a benchmark for AI research agents.
Key takeaway
For Machine Learning Engineers developing frontier models, recognize that open-ended learning and robust tool integration are becoming practical requirements, not just research aspirations. Your systems must continuously adapt to shifting data distributions and new tools, rather than relying on periodic retraining. Prioritize designing agents that can autonomously discover novel capabilities and recover from errors, moving beyond static prompt engineering to sequential decision-making with real-world constraints. This approach will yield more resilient and capable AI deployments.
Key insights
Open-ended learning and tool use are critical for AI models to adapt and continuously improve in dynamic, real-world environments.
Principles
- Open-endedness is a technical demand, not a slogan.
- Tool use introduces feedback loops, memory, and failure recovery.
- Decoupling value and policy improves RL generalization.
In practice
- Develop systems that learn without constant human task redefinition.
- Frame agent behavior as a sequential decision problem.
- Use benchmarks like MLGym to compare AI research agents.
