ComfyUI-Open-Sora-Plan

ComfyUI-Open-Sora-Plan requires a minimum of 128MB (0.1GB) of VRAM for base operation. For optimal performance, a GPU with at least 4GB of VRAM is recommended. This node supports low VRAM mode for resource-constrained setups.

✅ RTX 3060 (12GB): Yes, fully compatible with 10.7GB headroom. ✅ RTX 4070 (12GB): Yes, fully compatible with 10.7GB headroom. ✅ RTX 4070 Ti (16GB): Yes, fully compatible with 14.3GB headroom. ✅ RTX 4090 (24GB): Yes, fully compatible with 21.5GB headroom

ComfyUI-Open-Sora-Plan requires the following PyTorch-related packages: pytorch-lightning, pytorchvideo, torchdiffeq, torchmetrics. Ensure your ComfyUI environment has these installed. Ensure your PyTorch installation matches your CUDA version (use torch.version.cuda to check).

To run ComfyUI-Open-Sora-Plan, you need to install: accelerate, albumentations, av, beautifulsoup4, decord, diffusers, einops, ftfy, gdown, h5py, idna, imageio, imageio-ffmpeg, matplotlib, moviepy, omegaconf, opencv-python, opencv-python-headless, pandas, pillow, pydub, pytorch-lightning, pytorchvideo, pyyaml, regex, requests, scikit-learn, scikit-video, scipy, sentencepiece, six, tensorboard, test-tube, timm, torchdiffeq, torchmetrics, tqdm, urllib3, uvicorn, wandb. You can install these using pip or add them to your requirements.txt file.

ComfyUI-Open-Sora-Plan supports low VRAM mode. To reduce memory usage: (1) Enable --lowvram or --medvram flags in ComfyUI, (2) Reduce batch size to 1, (3) Use fp16 or fp8 precision if supported, (4) Close other GPU applications.

To install ComfyUI-Open-Sora-Plan: (1) Navigate to your ComfyUI/custom_nodes directory, (2) Clone the repository: git clone https://github.com/chaojie/ComfyUI-Open-Sora-Plan, (3) Install dependencies: pip install -r requirements.txt (if present), (4) Restart ComfyUI. Alternatively, use ComfyUI Manager for one-click installation.
