I will present the latest results from JWST on the detection of the host galaxies of z ~ 6 quasars. These observations enable us to establish the early mass relation between black hole mass and galaxy stellar mass using NIRCAM and NIRSPEC. This involves careful 2D decomposition of IR images with accurate characterization of the point-spread function, selection effects, and measurement uncertainties. Furthermore, rest-frame spectroscopy is revealing the timescales for galaxy and SMBH growth. I will also discuss the connection with lower mass black holes found in deep JWST surveys as reported in the literature and need to consider selection effects.
