How to run Wan2.1 T2V-1.3B locally

Alibaba (Wan-AI) · Text → video · 1.3B params · Apache-2.0 (commercial OK)

The tiny 1.3B Wan2.1 model that runs 480p video on ordinary 8GB consumer GPUs, the most accessible entry point into open video generation.

What it costs to run — $0 markup

• On your own machine — $0. Runs free if you have about 8.0 GB of VRAM (only ~8.2GB VRAM; 5s 480p in ~4min on an RTX 4090), via ComfyUI / Diffusers.
• Rent a GPU — from $0.26/hr. Fits RTX 3090 24GB at the direct vendor price ($0 markup) — pay only for the minutes you generate.
• Download the weights — free. Open weights at Wan-AI/Wan2.1-T2V-1.3B.

Note: generative-media models are billed per image / per second / per minute on hosted services — not per token. Running locally or on your own rented GPU is usually far cheaper and keeps your data on your machine.
