Higher realtime means faster processing speeds. Comparison on CPU are coming soon. | Model | Speed (Real-Time) | Model Size | | :------------ | :---------------- | :--------- | | **NovaSR** | **3600x realtime** | **~52 KB** | | FlowHigh | 20x realtime | ~450 MB | | FlashSR | 14x realtime | ~1000 MB | | AudioSR | 0.6x realtime | ~6000 MB | ## Usage Please check out the github repo for usage: https://github.com/Saganaki22/ComfyUI-NovaSR Original Repo: https://github.com/ysharma3501/NovaSR If you find the model/code helpful, stars or likes would be appreciated.
