PixelDiT

Single-stage, end-to-end pixel-space diffusion transformer that generates high-res images directly with no VAE, using a dual-level design (patch-level DiT for global semantics + pixel-level DiT for texture). Achieves 1.61 FID on ImageNet 256 and 0.74 GenEval; the Comfy-Org repo ships ~61GB of ComfyUI-ready safetensors incl. 512→2048 and 1024→4096 upscalers. (CVPR 2026 Best Paper Finalist.)
