Hosted by Brookhaven National Laboratory, the TREASURE Workshop (April 27–29, 2026) is dedicated to the development of tokenized data representations for high-energy physics. As AI continues to revolutionize scientific discovery, the TREASURE initiative seeks to standardize how collider data is prepared, represented, and utilized by Large Language Models and other foundation architectures. Join us for three days of technical sessions, collaboration, and roadmap-building as we define the next generation of AI-driven HEP searches.
