Blazars emit across all electromagnetic wavelengths. While the so-calledone-zone model has described well both quiescent and flaring states, it cannotexplain the radio emission and fails in more complex data sets, such as APLibrae. In order to self-consistently describe the entire electromagneticspectrum emitted by the jet, extended radiation models are necessary. Notably,kinetic descriptions of extended jets can provide the temporal and spatialevolution of the particle species and the full electromagnetic output. Here, wepresent the initial results of a newly developed hadro-leptonic extended-jetcode: ExHaLe-jet. As protons take much longer than electrons to lose theirenergy, they can transport energy over much larger distances than electrons andare therefore essential for the energy transport in the jet. Furthermore,protons induce injection of additional pairs through pion and Bethe-Heitlerpair production, which can explain a dominant leptonic radiation signal whilestill producing neutrinos. In this talk, we discuss the differences betweenleptonic and hadronic dominated SED solutions, the SED shapes, evolution alongthe jet flow, and jet powers. We also highlight the important role of externalphoton fields, such as the accretion disk and the BLR.
