Description
OmniJet-alpha, the first cross-task foundation model for particle physics, was first presented at ACAT 2024. In its base configuration, OmniJet-alpha is capable of transfer learning between an unsupervised problem (jet generation) and a classic supervised task (jet tagging). Since its release, we have also shown that it can sucessfully transfer from CMS Open data to simulation, and even generate calorimeter showers. This talk will give an overview of the model, and present the latest developments and results.
