AI Image Prompt Cheat Sheet

The universal prompt formula, per-model syntax, and keyword tables for Midjourney, DALL-E 3, Stable Diffusion, and Flux β€” on one page. Free to use and share.

The universal prompt formula

Every strong image prompt, regardless of model, follows the same skeleton. Fill each slot and you have a professional prompt:

[subject] + [action/pose] + [environment] + [composition] + [lighting] + [color/mood] + [style/medium] + [camera/lens] + [quality] + [model parameters]

Example: a red fox, curled asleep, in a snowy pine forest, centered composition, soft morning backlight, cool blue palette, photorealistic, 85mm f/1.8, ultra-detailed --ar 3:2 --v 6

Midjourney parameters

ParameterWhat it does
--ar W:HAspect ratio, e.g. --ar 16:9, --ar 3:2, --ar 1:1
--v 6Model version (latest: 6). --niji 6 for anime.
--stylize 0–1000How strongly Midjourney applies its aesthetic. Low = literal, high = artistic.
--chaos 0–100Variety across the 4 results. High = more unexpected.
--weird 0–3000Pushes toward unusual, offbeat aesthetics.
--quality .25–1Render time/detail. Lower = faster, cheaper.
--seed 0–4294967295Reproducibility. Same seed + prompt = similar image.
--no XNegative prompt β€” exclude X (e.g. --no text, watermark).
--tileSeamless repeating pattern.
--cref URLCharacter reference for consistent characters.

Stable Diffusion syntax

SyntaxEffect
(word:1.3)Increase a term’s weight (emphasis). 1.0 = neutral.
(word:0.6)Decrease a term’s weight.
((word))Shorthand emphasis (~1.21Γ— per pair).
Negative promptSeparate field β€” list what to avoid: blurry, lowres, extra fingers, watermark, text.
CFG scale 5–12How strictly it follows the prompt. ~7 is balanced.
Steps 20–40Sampling steps. More = cleaner, slower.
SamplerDPM++ 2M Karras / Euler a are common defaults.

DALL-E 3 & Flux tips

  • DALL-E 3: prefers full natural-language sentences over keyword lists. Describe the scene like you would to a person. No parameter syntax.
  • DALL-E 3: excellent at rendering text in images β€” quote the exact words: a sign that reads "OPEN".
  • Flux: handles long, detailed natural-language prompts well and renders text reliably. Be specific about composition and lighting.
  • Flux: no negative prompt β€” phrase positively (say what you want, not what you don’t).

Lighting keywords
