I will talk about the physics of Galactic cosmic rays (CRs) with a special emphasis on the high-energy interstellar emission. The data collected with the Large Area Telescope (LAT) on board the Fermi satellite has revolutionized our understanding of the high-energy interstellar emission and the distribution of CRs in the Galaxy. Direct observations of CRs by the Alpha Magnetic Spectrometer (AMS-02) on board the international space station with its unprecedented accuracy also provide serious constraints on CR propagation model. I will review some of the highlights from both instruments and discuss how this has affected the development of the GALPROP CR propagation code and the data analysis methods.
