CERN Signs Statement of Intent With Mistral AI to Build Large Physics Model

On October 15, 2026, the European Laboratory for Particle Physics (CERN) signed a statement of intent with French AI developer Mistral AI to build a pretrained Large Physics Model for high-energy physics. The foundation model is expected to train on billions of simulated proton-proton collision events linked to the Large Hadron Collider (LHC), which has already generated close to one exabyte of experimental data. The initiative targets replacing narrow, single-task algorithms with a general-purpose tool capable of handling collision reconstruction from detector signals and flagging anomalies that deviate from known physics predictions. CERN is preparing for its High-Luminosity LHC upgrade projected for around 2030, which is expected to increase collision rates by a factor of ten and overwhelm traditional data analysis pipelines. While Mistral AI brings experience from its 1-trillion-parameter Mistral Large 4 previewed on October 6, 2026, neither organization has disclosed specific funding figures, deadlines, or binding milestones beyond the initial statement of intent.
