CERN and Mistral Partner to Develop Foundation Model for Collider Physics

Details

CERN and Mistral signed a statement of intent to establish a long-term strategic partnership for developing foundation models for scientific discovery, with an initial focus on high-energy physics.
The core objective is to create a single pretrained Large Physics Model, the first foundation model for collider physics, designed to support multiple tasks including particle collision reconstruction, particle identification, and flagging unexpected signals.
The model will be trained on billions of simulated proton-proton collisions from the Large Hadron Collider (LHC), leveraging CERN's approximately one exabyte of experimental data and Mistral's large-scale model training capabilities.
This approach aims to replace the current chain of specialized algorithms with a unified model that learns across the entire reconstruction chain, potentially serving the broader scientific community beyond high-energy physics.
The partnership is expected to benefit from the tenfold increase in collision data anticipated with the High-Luminosity LHC (HL-LHC), which is expected to begin operation around 2030.
