Hybrid Model Advantages
The Wan 2.1 5B is a hybrid model, meaning you can generate both Text-to-Video and Image-to-Video using the exact same model.
Tips for Low VRAM Users
This model is very budget-GPU friendly; it runs smoothly even on 8GB VRAM thanks to optimizations within ComfyUI.
Storage Space Reminder
Make sure you have enough storage space (at least 20GB+) before starting the download, as the combined size of the model, VAE, and encoder is quite large.
