How to Use Wan 2.2 for Free AI Video on Your Own PC

Wan 2.2 is Alibaba’s open-weight video generator, and the big draw is that you can render unlimited clips on your own hardware with no per-generation charge. It comes in several sizes, from a lightweight 5B version that fits modest GPUs to a 14B version for higher quality. Commercial use is allowed under its license.

What is Wan 2.2?

It is a text-to-video and image-to-video model released as open weights, trained to handle realistic motion and camera movement. The smaller 5B variant targets consumer cards; the 14B variant wants more VRAM but produces cleaner detail. Because it is open, you can also fine-tune it on your own footage, which closed services do not allow.

What hardware do I actually need?

You have options depending on VRAM:

• 8GB (e.g. RTX 3060 Ti): the 5B model at 480p, with offloading enabled.
• 12GB (RTX 3060 12GB): 5B at 720p is workable.
• 24GB (RTX 4090): the 14B model at 720p runs comfortably.

System RAM matters too — 32GB is a sane minimum, because weights spill over when VRAM runs out.

How do I install and run it?

1. Install Python 3.10+ and CUDA drivers for your card.
2. Set up a venv and install PyTorch for your CUDA version.
3. Grab the Wan 2.2 weights from the official model repo.
4. Install ComfyUI — it has first-class Wan support through official workflow templates.
5. Load the provided Wan text-to-video template and swap in the checkpoint.
6. Set resolution, frame count, and seed, then queue.

Wan ships reference workflows, so you do not build the graph from scratch. Start with the template and adjust one setting at a time.

Is Wan 2.2 really free?

The weights are free to download and run, and there is no metered fee. Your real cost is the GPU and electricity. That is a genuine advantage over hosted tools that charge per second of video — if you render often, the hardware pays for itself. The trade-off is time: local renders are slower than a cloud service on equivalent quality, and you handle all the troubleshooting.

Wan 2.2 vs hosted generators

Against Seedance 1.5, Wan 2.2 loses on native audio and out-of-box polish but wins on cost-per-clip and fine-tuning freedom. Against Hunyuan Video 2, the two are close; Wan’s smaller 5B model runs on weaker GPUs, which makes it the friendlier entry point for a mid-range card.

Quick Summary

• Wan 2.2 is Alibaba’s open-weight video model with 5B and 14B variants.
• An 8GB card runs the 5B model at 480p; 24GB runs 14B at 720p.
• Install via ComfyUI with the official Wan workflow templates.
• No per-clip fee — you pay in hardware and render time instead.
• Beats hosted tools on cost and customization, loses on audio and convenience.
