Minimax H3 Image T2I & I2I Simple Workflow 1girl

Onyx Basic – MiniMax H3 Image (T2I + Edit)

Two clean, simple workflows for MiniMax H3 Image, built on native ComfyUI nodes (+ CRT for grain). Ultra-realistic smartphone-style photos at native 16 MP in 6 steps.

T2I – write a detailed English description and run.
Edit – up to 4 reference images (<Picture 1>, <Picture 2>…): keep your character, change outfit, scene or pose. Official MiniMax prompt enhancer built in (on/off): a short instruction is enough, it writes the full description for you.
