tl;dr: CERN and Mistral have signed a statement of intent to build a Large Physics Model, a foundation model for collider physics trained on billions of simulated proton-proton collisions from the LHC. The model aims to unify tasks currently handled by specialized algorithms—reconstructing collisions, identifying particles, detecting anomalies, and evaluating detector designs—within a single pretrained system. CERN brings roughly one exabyte of experimental data and domain expertise, while Mistral contributes large-scale model training capabilities, with the collaboration positioned ahead of the HL-LHC's expected 2030 start.
