At the pinned READMEs, the smallest self-reported memory figures are: Wan2.1 T2V-1.3B 8.19 GB (480P), CogVideoX diffusers from 3.6 GB (2B INT8) and 4 GB (2B FP16), HunyuanVideo-1.5 14 GB minimum with offloading (resolution and length not stated), Wan2.2 TI2V-5B 24 GB at 1280*704, HunyuanVideo (v1) 45 GB at 544x960x129 frames and Mochi 1 about 60 GB. The figures are not comparable with each other: they differ in resolution, frame count, offloading and whether weights or peak memory are meant. A beginner should read each figure together with the stated resolution and flags, and treat a missing setting as unknown.

Curator qualifications: Verified the smallest figures and the non-comparability caveat. Addition: the Mochi README itself notes ComfyUI can run Mochi in under 20 GB (a third-party optimisation claim in the vendor README). Add the Mochi README's '<20GB via ComfyUI' note next to the 60 GB figure.
