FoPt is located at COLT 2025 and will be organized in the beautiful city of Lyon, France on the 30th of June, 2025. This workshop seeks to explore the theoretical and practical aspects of the post-training of LLMs, across a diversity of domains and abstractions. The workshop aims to bring together experts from diverse fields including theoretical reinforcement learning, optimization, statistical learning theory, as well as more empirical directions, to identify critical research opportunities.
