Feedback from AGN jets is critical for heating the intracluster medium (ICM) and preventing cooling catastrophe in cool-core (CC) clusters. However, the composition of AGN jets and the resulting feedback processes remain uncertain. In this talk, I will describe how we model the effects of cosmic rays (CRs) in numerical simulations and present results comparing leptonic vs. hadronic jets in terms of AGN feedback in clusters. I will also discuss their observational signatures and whether they could allow us to distinguish the different scenarios. Finally, I will talk about our recent results on modeling of the Fermi/eRosita bubbles as a nearby example of leptonic jet feedback in galaxies.
