Wan2.1-I2V-14B-480P-StepDistill-CfgDistill-Lightx2v is an advanced image-to-video generation model built upon the Wan2.1-I2V-14B-480P foundation. This approach allows the model to generate videos with significantly fewer inference steps (4 steps) and without classifier-free guidance, substantially reducing video generation time while maintaining quality.

## Quantization
|
| 35 |
The model weights have been partially quantized to **NVFP4** (NVIDIA Floating Point 4-bit), a quantization format supported on NVIDIA Blackwell architecture GPUs. Only a subset of the model layers have been quantized; the remaining layers are kept at their original precision to preserve output quality.
