<p class="MsoNormal"><b>Abstract:</b> The Learning the Universe collaboration is developing an accelerated mock pipeline for simulation-based inference of galaxy formation and cosmology, combining state-of-the-art machine learning techniques with modern cosmological
simulations. By integrating high-resolution simulations, fast emulators, and inference techniques, our approach enables the efficient and precise extraction of cosmological information from large-scale structure surveys. In this talk, we will present our methodology
and highlight its application to the SDSS BOSS CMASS spectroscopic galaxy sample, demonstrating its effectiveness in constraining cosmological models with field-level information. We will also discuss our developing plans for modeling next-generation surveys,
including state-of-the-art, field-level halo and galaxy emulators. As one example, we recast the forward modeling of galaxies from N-body simulations as a language translation problem, enabling the use of transformer-based architectures to map between dark
matter fields and galaxy catalogs.<o:p></o:p></p>
