# Wan2.1-T2V-1.3B Distill Example
|
||||
These are end-to-end example scripts for distilling Wan2.1 T2V 1.3B model using DMD-only and DMD+VSA methods.
|
||||
|
||||
### 1. Download dataset:
|
||||
```bash
|
||||
bash examples/distill/Wan-Syn-480P/download_dataset.sh
|
||||
```
|
||||
|
||||
### 2. Configure and run distillation:
|
||||
|
||||
#### For DMD-only distillation:
|
||||
```bash
|
||||
sbatch examples/distill/Wan-Syn-480P/distill_dmd_t2v.slurm
|
||||
```
|
||||
|
