Summary

Melvin generated portraits with the Z-Image-Turbo image model in ComfyUI on a local RTX 3090 GPU, at no cost. It shows that you can run good open image models on your own consumer hardware.

Key points

• It runs locally with ComfyUI, a node-based workflow tool.
• A consumer RTX 3090 (24 GB VRAM) is enough, and generation is free.
