5-Second Video in 1.8 Seconds on RTX 5090

1.8 Seconds to Generate 5-Second Video! This AI Model Eliminates Waiting

Do you remember the pain of staring at a progress bar spinning for half a day last time you used AI to generate video?

Sky Computing Lab recently released FastWan-QAD, claiming that on a single RTX 5090 graphics card, it can generate a 5-second 480P video in just 1.8 seconds.

Technical Highlight: Quantization-Aware Distillation (QAD)

They used a technique called Quantization-Aware Distillation. In plain language: let the large model teach the small model, while considering compression during training, so the trained small model is both fast and accurate.

Why 1.8 Seconds Matters?

Video generation has always had a pain point: too slow. If it can really be generated in 1.8 seconds, that means: real-time preview, fast iteration, reduced cost.

It's Open Source!

Sky Computing Lab has open-sourced the models, code, and blog. This means developers can deploy it themselves without relying on APIs.

My Take

This direction is very correct. The next competition point for AI video generation is speed and accessibility, not just quality.

**Good for**: Video creators, AI developers, marketing teams who want to quickly generate video content.
