Wan2.1 (T2V-1.3B) — Multi-GPU Gradio demo

Gradio demo for testing Wan-AI/Wan2.1-T2V-1.3B running on 8x A100 (640 GB) with the official multi-GPU recipe from the model card:

torchrun --nproc_per_node=8 generate.py --task t2v-1.3B --size 832*480 \
    --ckpt_dir ./Wan2.1-T2V-1.3B --dit_fsdp --t5_fsdp --ulysses_size 8 \
    --sample_shift 8 --sample_guide_scale 6

• FSDP shards the DiT and the UMT5-XXL text encoder across all 8 GPUs
• xDiT USP (Ulysses sequence parallelism) splits the sequence across 8 GPUs for faster generation
• ~17.5 GB of checkpoints are baked into the Docker image

Default settings follow the official demo: 480P (832*480), 50 steps, guide scale 6, shift 8, 16 fps, 81 frames (5 s).
