Flux
prompt generator.

FLUX models read natural language and follow detailed descriptions closely, but they don’t support a negative prompt. Anything you want to avoid has to be expressed positively.

The generator writes a flowing description from your selections and converts common negatives into positive statements — for example “an authentic photograph, not a render” instead of “no CGI”.

Example outputStudio product shot
Commercial product photography, minimalist, photorealistic. Close-up product shot, square 1:1 frame, subject large and dominant in frame. The subject is a product, a glass skincare bottle standing on a wet stone pedestal with water droplets. Set in a professional photo studio, background seamless solid color backdrop, minimal, nearly no distracting objects. Large softbox studio lighting, diffused and even, reflections on surfaces. Shot on a full-frame DSLR, macro lens, camera eye level, deep focus, everything sharp. Centered subject, empty space at top for text. An authentic photograph, not a render or illustration. A clean frame with no text, logos or watermarks.

How to write better Flux prompts.

01

Write in full sentences

Flux understands relationships between objects, so describe how things are arranged rather than listing them.

02

Rephrase exclusions positively

Instead of “no watermark”, describe a clean frame with no text. The generator does this automatically for common cases.

03

Be specific about the camera

Lens, distance and depth of field strongly influence the look of Flux photos.

04

Use Kontext for edits

For editing an existing image, use a Flux Kontext model and say plainly what to keep and what to change.

Flux FAQ.

Why is there no negative prompt field for Flux?+

Flux models don’t use negative prompts, so the generator folds important exclusions into the positive description instead.

Does this work with local Flux setups?+

Yes. The prompt is plain text, so it works in ComfyUI, Forge or any Flux interface.
