# Tiny FastWan2.1 T2V DMD Debug Pipeline

This is a randomly initialized, tiny `WanDMDPipeline` fixture for `FastVideo/FastWan2.1-T2V-1.3B-Diffusers`.
FastVideo FastWan2.1 DMD-style text-to-video layout represented as a Diffusers-format artifact with `_class_name` patched to `WanDMDPipeline` for FastVideo `VideoGenerator` load-path debugging.

It is intended for fast load-path and inference-control debugging only. It is not trained and should
not be used for generation quality evaluation.

```python
import os
from fastvideo import VideoGenerator

os.environ["FASTVIDEO_ATTENTION_BACKEND"] = "TORCH_SDPA"
generator = VideoGenerator.from_pretrained(
    "Erland/tiny-fastwan2.1-t2v-dmd-debug",
    num_gpus=1,
)
try:
    generator.generate_video(
        "debug prompt",
        output_path="my_videos/",
        save_video=True,
    )
finally:
    generator.shutdown()
```
