⚡ Cross-Space Distillation: Teaching One-Step Students with Modern Diffusion Teachers got accepted at ECCV. This work removes a hidden constraint in fast diffusion distillation: Teacher and Student no longer need to live in the same latent space. We formalize Cross-Space Distillation and introduce Bridge, a lightweight latent-space interface that makes standard one-step distillation possible across mismatched resolutions, VAEs, architectures, and diffusion/flow paradigms.
