We will discuss the non-equilibrium dynamics of a low 
temperature 2-dim black hole coupled to an external bath, using the dual 
SYK model. Tracing over the bath degrees of freedom, in the 
Schwinger-Keldysh formalism, leads to solving non-local stochastic 
differential equations for the BH degrees of freedom. We describe the 
combination of SYK operators that enable complete evaporation of the BH, 
and the fluctuations that characterise the end point of the evaporation 
process. This talk is based on JHEP 08 (2023) 171 (arXiv:2210.15579).
