Notes: Wan 2.2's unified 5B text-and-image-to-video model (720p, 121 frames at 24fps). The official spec asks for a 24GB GPU with offload, but ComfyUI native offloading fits it well on 8GB, and GGUF Q4_K_M (3.43GB) + T5 on CPU lands around 5-8GB. Note the larger 2.82GB Wan 2.2 VAE. Apache-2.0, commercial OK. Anchor is the ComfyUI 8GB path (synthesis). Sources: Wan-AI card, QuantStack GGUF, ComfyUI Wan 2.2 tutorial, Wan2.2 repo.
