MiniMax H3 Image & P-H3-Image Prompt Guide

Distilled 6-step and 8-step H3 Image models run without classifier-free guidance or negative prompts. Use the four official prompting rules and <Picture 1>–<Picture 4> edit templates below, or launch any benchmark directly in the studio.

Four Prompt Rules from the H3 Image Model Card

Why short tag-soup prompts fail on H3 Image — and how to structure sentences that render clean hands, real skin texture, and sharp typography.

Rule 01

Say What the Image Is in the First Sentence

Naming the physical medium first ("A two-color risograph print", "An overhead knolling photograph", "A character reference sheet") anchors texture and lighting better than generic style buzzwords.

Avoid: A cyberpunk girl in Tokyo rain, 8k, ultra detailed, masterpiece.
Write: A candid street photograph taken by a friend with a 35mm camera on a rainy Tokyo side street at dusk...
Rule 02

Describe One Concrete Scene & Light Direction

Give a camera viewpoint, one primary subject in a specific moment, a few supporting props, and a clear light source with direction.

Avoid: Cool room with sofa, table, lamp, dramatic vibes, hyper-realistic.
Write: Warm morning sunlight streaming through tall factory windows on the left, casting crisp natural shadows across herringbone oak floors.
Rule 03

Quote Every Text String in "DOUBLE QUOTES"

Unquoted text turns into pseudo-text. Put exact words in quotes, specify where they sit on the canvas, and end with "no other text".

Avoid: Poster with night ride text at the top and saturday 9pm.
Write: The words "NIGHT RIDE" sit in bold geometric block letters across the top and "SATURDAY 9 PM" in small clean letters at the bottom right, no other text.
Rule 04

Leave Out Hype Words (No CFG / 6–8 Steps)

Both MiniMax-H3-Image (6 steps) and P-H3-Image (8 steps) are distilled with no classifier-free guidance. Hype words push them toward an oversaturated, plastic look.

Avoid: stunning, epic, vibrant, hyper-detailed, 8k, unreal engine, masterpiece
Write: visible skin texture, slight motion blur on her hand, mixed window and tungsten light, no retouching
