In April 2019, the Event Horizon Telescope (EHT) released the first-ever image of a black hole. To produce this image required days to weeks using high-performance and distributed computing. In the next decade, the next-generation EHT will come online, increasing the complexity of black hole imaging by 2-3 orders of magnitude, thus making current tools impractical. In this talk, we introduce Comrade, a Julia-based Bayesian black hole imaging code recently developed for the next-generation EHT. Furthermore, we will describe how Julia and Enzyme AD enabled a 10-100 times higher performance increase, moving black hole imaging from clusters to a laptop.
