HiLo-Token Cuts DiT Latency for Image Editing via Adaptive Token Compression

HiLo-Token is an input-adaptive token compression framework targeting Diffusion Transformer latency in image editing pipelines, where the DiT module accounts for 73% of total latency even after distillation to 8 timesteps. The method allocates token budget based on high- vs. low-frequency content regions, reducing compute without uniform quality loss.
