Running Hunyuan with 8GB VRAM and PixArt Model Support
Blog post from Comfy
ComfyUI has released version 0.3.10, which significantly reduces the VRAM requirements for running the HunyuanVideo model, lowering it from 32GB to just 8GB, through the introduction of temporal tiling in video VAEs. Temporal tiling differs from spatial tiling by expanding each temporal latent dimension by 4x, except for the last one, allowing for more efficient video processing. Additionally, ComfyUI now supports PixArt models, including Alpha and Sigma versions, for high-quality diffusion image generation, thanks to community contributions. Users can update to the latest version of ComfyUI to access these features and are invited to join bi-weekly office hours on Discord for discussions, feedback, and community interaction.
