Strong gravitational lensing is a powerful probe of dark matter and cosmology, but modelling the large samples expected from upcoming surveys like Rubin/LSST requires fast, differentiable simulators. Caustics provides GPU-accelerated lensing forward models with automatic differentiation, enabling gradient-based inference at scale.
