Jet physics is entering a precision era in which progress increasingly depends on our ability to control soft-QCD effects and experimental biases. In this seminar, I will present the first inclusive charged-particle jet measurement from ALICE Run 3: the R dependence of jet cross sections in pp collisions at $\sqrt{s}=13.6$ TeV. This measurement provides a sensitive probe of non-perturbative QCD dynamics and reveals differences of up to 30% among modern event generators in the low transverse momentum, large-radius regime.

I will place this result in the broader context of the Run 3 heavy-ion and small-system jet program, including ongoing studies of jet quenching in small systems, jet substructure, and medium response measurements in O+O and Pb+Pb collisions. In particular, I will discuss ongoing work on the ALICE O+O charged-particle jet R_AA measurement, which extends hadron suppression measurements into the jet sector. Finally, I will briefly discuss how AI and machine-learning approaches may help address future challenges in jet physics.
