# WAN 2.1 T2V 720p

> Open-source text-to-video generation for creating 720p videos from text prompts.

WAN 2.1 T2V 720p is an open-source video generation model for creating 720p videos directly from text prompts. It uses a diffusion transformer architecture to generate high-quality video content without requiring a source image.
