+### Parallel Inference
+
+1. Unified Sequence Parallel (USP)
+
+```bash
+pip install xfuser>=0.4.3
+```
+
+```bash
+torchrun --standalone --nproc_per_node=8 ./wan_14b_text_to_video_usp.py
+```
+
+2. Tensor Parallel
+
 Tensor parallel module of Wan-Video-14B-T2V is still under development. An example script is provided in [`./wan_14b_text_to_video_tensor_parallel.py`](./wan_14b_text_to_video_tensor_parallel.py).
