Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release. They were produced by the Astrophysical parameters inference system (Apsis) within the Gaia Data Processing and Analysis Consortium. This presentation gives an overview of the over 40 different parameters and their variants produced by 13 Apsis modules for Gaia DR3, from classifications to stellar spectroscopic and evolutionary parameters to extra-galactic redshifts. It describes where they can be found in the Gaia archive, how they were produced, and gives best practice usage advice. Selected examples from Gaia DR3 performance verification papers are also presented, in which the parameters were analysed to demonstrate the high quality of these data products and to illustrate their science potential.
