Image Prompt Builder
Write a prompt for Midjourney, Flux, Stable Diffusion or GPT Image, explain the parameters of one, and convert it from one model's syntax to another's
Image
Who or what, doing what. The start of a prompt weighs the most.
Naming a real camera, lens or film stock does more for a photo than “professional photo”.
Names or hex codes, separated by commas. A hex code becomes the nearest color name for the models that don't read them.
Separated by commas. Written as a negative prompt, a
--no or a sentence, depending on the model.A Midjourney prompt, a Stable Diffusion one (with its negative prompt and settings, as Civitai and AUTOMATIC1111 copy them), a FLUX.2 JSON prompt, or plain words.
What each part does
| Part | Meaning | For Midjourney |
|---|
Midjourney
Low follows the prompt closely, high gives Midjourney's own taste more room.
How different the four images are from one another.
More detail and punch; above 25 it can drown the prompt and the other settings.
Flux
Format
FLUX.2 reads both as well; JSON keeps a scene with several subjects in order.
Stable Diffusion
Most checkpoints of Civitai are built on one of these: its page says which.
Model
They read plain sentences; what changes is the sizes they offer, and where what to leave out goes.
Prompt
Negative prompt
