Wan 2.2 (Text to video, A14B) needs 14.5 GB of VRAM in ComfyUI, at the diffusion stage of its own template, by file sizes read 3 November 2026. The smallest card that loads it with room to work is the RTX 4090 (24 GB), and the template downloads 35.6 GB.

For each memory size, the best file for that card: the highest-precision diffusion file that loads with room to work (one that only just fits when nothing else does), and what is left for working memory while it samples. On a larger card that can be above the file ComfyUI's template loads, which the answer above is about. "Streams" means even the smallest file is larger than the card: ComfyUI still runs it from system RAM, more slowly. FP4 files go only to the Blackwell cards that run them natively.

Wan 2.2 5B, a 5-second 720p video, on rented cards in Finland on 20 October 2026. With every model loaded, the 121-frame video took about 31 GB, against a largest stage of 11.4 GB: working memory comes on top.

Wan 2.2 is Wan's open video model. Alibaba's Wan 2.2, from July 2025, remains the newest Wan with open weights. The A14B models are two 14-billion-parameter experts that take turns, one for the rough layout and one for detail. TI2V-5B is a single smaller model with a more compressed VAE, and Animate 2 (August 2026) is the character-animation model in the same family.

Those figures and this page measure different things. A vendor's figure covers its own script at its default resolution and length, working memory included. This page counts the weights each stage holds, which is exact, and leaves the working memory as the space that remains, because it depends on your resolution, frame count and attention kernel and nobody publishes it per model. If generation runs out of memory with a file that loads, lower the resolution or the frame count before stepping down a precision. ComfyUI's README says it "can run even the biggest open source models on as low as 4GB vram + 8GB ram" by streaming weights (source), so "streams" means slower, not impossible.
Wan 2.5, 2.6, 2.7 and 3.0 have no open weights (checked 2026-10-02). None has open weights on Hugging Face (Wan-AI), ModelScope or GitHub (Wan-Video). Wan offers them through Alibaba Cloud Model Studio, the Wan website, the Qwen app and Qwen Cloud, and has not said they will be released.
Only configurations a trainer's own documentation gives a VRAM figure for. Settings change the figure a great deal, so read the setting column before trusting the number.
