Wan2.2-TI2V-5B-Turbo-Diffusers

This repo is the Diffusers version of quanhaol/Wan2.2-TI2V-5B-Turbo

Wan2.2-TI2V-5B-Turbo is designed for efficient step distillation and CFG distillation based on Wan2.2-TI2V-5B.

Leveraging the Self-Forcing framework, it enables 4-step TI2V-5B model training. Our model can generate 121-frame videos at 24 FPS with a resolution of 1280×704 in just 4 steps, eliminating the need for the CFG trick.

To the best of our knowledge, Wan2.2-TI2V-5B-Turbo is the first open-source repository of the distilled I2V version of Wan2.2-TI2V-5B.

Blurred beach scenery forms the background featuring crystal-clear waters, distant green hills, and a blue sky dotted with white clouds. The cat assumes a naturally relaxed posture, as if savoring the sea breeze and warm sunlight. A close-up shot highlights the feline's intricate details and the refreshing atmosphere of the seaside."
