Z Image HSWQ fp8e4m3.safetensors & Nunchaku R128 SVDQ-FP4 i2i with Upscaler＆Face Detailer＆Union ControlNet

23.03.2026, updated HSWQ fp8e4m3 version.

I think ZIT is so useful, especially for the real photo.

Until now, I have mainly used the Flux1 i2i, but the ZIT i2i is an alternative to replace it.
