In this picture, the star evolves under accretion rates of $0.1 - 1$ $M_\\odot$ yr$^{-1}$ until the general relativistic instability triggers its collapse to a black hole at masses of $\\sim10^5$ $M_\\odot$. However, the ability of the accretion flow to sustain such high rates depends crucially on the photospheric properties of the accreting star, because its ionising radiation could reduce or even halt accretion.
