For those who, like me, aren't exactly experts:

Use the specific NVFP4 version—namely,

FinePorn_V4_nvfp4_nvfp4.safetensors

by

...designed for NVIDIA Blackwell 5000 GPUs (though it can be used with others).

A quick workflow for excellent image quality (110 seconds for a 21:9 UltraWide image on an RTX 5070 Ti with 16GB VRAM; this drops to 60 seconds if using a single last KSampler). The process relies on simple image concepts that are then refined by the text encoder itself.

Tip: Bypass the first two KSamplers!

Any feedback is welcome.

I hope the AI ​​helped me write the instructions correctly; thanks to the original creators of the nodes, models, and workflows.
