Researchers have introduced Loop Flow Transformers (LiFT), a novel family of generative models. LiFT scales computation by repeatedly applying a shared Diffusion Transformer (DiT) core with minimal architectural changes. Each step in the loop is trained with a single regression target, allowing the model to loop beyond its training depth without retraining. This approach improves generation quality and allows inference computation to increase without adding parameters. On ImageNet at 256x256 resolution, LiFT-L/2 achieved a lower FID score than a dense DiT-XL/2 baseline while using significantly fewer parameters and training/inference FLOPs. AI
