Flux 1.1 Pro Prompt Generator

Flux 1.1 Pro is a long-context image model from Black Forest Labs that rewards paragraph-length natural-language prompts over keyword soup. Unlike earlier models that needed "8k, ultra detailed, masterpiece" padding, Flux parses full sentences and extracts semantic structure - subject, verb, setting, lighting - with remarkable accuracy. The best Flux prompts read like a director briefing a photographer: specify the subject (gender, age range, attire, expression), then the lighting (golden hour, soft window, cinematic rim), the lens (35mm wide, 85mm portrait, macro), the composition, and the mood, all flowing as one paragraph. This generator turns your single-line idea into exactly that shape, drawing on the Flux team's published prompting guide and thousands of community benchmarks. When you're happy with the text output, pair it with our Flux image-to-prompt tool to reverse-engineer reference photos, or switch the model selector above to compare how the same idea translates for Midjourney, Imagen 3, or SDXL - the differences are often striking.

Frequently asked questions

What makes a great Flux 1.1 Pro prompt?+
Flux 1.1 Pro responds best to long, descriptive prose - the way you'd brief a photographer. Skip the keyword spam ("8k, ultra detailed, masterpiece") and instead describe the subject, the lighting, the lens, the framing, and the mood as one continuous paragraph. Specifying 35mm or 85mm, golden hour vs studio lighting, and shallow vs deep depth of field gives Flux meaningful steering signals.
What is an AI prompt generator?+
An AI prompt generator rewrites a short idea into a longer, model-specific instruction that steers an image model toward better, more predictable results. Different models prefer different prompt styles - Flux likes long natural language, Stable Diffusion likes a hybrid of description plus tags, Midjourney likes terse evocative phrasing with parameter flags, and Nano Banana 2 likes plain logical instructions.
Is the AI prompt generator free?+
Yes. Anyone can generate up to 5 prompts per day at no cost, no sign-up required. If you need more, the EdMyPic Free plan includes 5 photo edits per day plus unlimited prompt generation when signed in.
Which AI image models does this support?+
Eleven major models out of the box: Flux 1.1 Pro, Midjourney v6, DALL·E 3, Stable Diffusion 3, Stable Diffusion XL, Ideogram 2, Leonardo AI, Google Imagen 3, Google Nano Banana 2, Adobe Firefly, and Recraft V3. Each one ships with a hand-tuned system prompt - pick the model you'll be generating with so the output matches its conventions exactly.
How do I get the best results from a prompt generator?+
Start with a clear subject (who or what), a verb (what they're doing), and one stylistic anchor (e.g. golden hour, cinematic, watercolor). The generator handles the rest - composition, lens, lighting, and mood - based on the model you selected.
Can I use the generated prompt commercially?+
Yes. The prompt itself is just text - you own anything you generate from it. Commercial usage of the resulting image depends on the image model you're using; Flux, SD3, and Midjourney all support commercial output on their paid tiers.
Why does the same idea give different prompts for different models?+
Each model was trained on different data with different guidance objectives. A description that nails a photoreal portrait in Flux 1.1 Pro will under-perform in Midjourney unless you switch to Midjourney's more compact, flag-based syntax. The model selector handles that translation automatically.
Do I need to know prompt engineering to use this?+
No. The whole point of the tool is that you don't. Type a rough idea like "a barista smiling at golden hour" and you'll get back a fully-formed prompt that incorporates the photography, composition, and mood cues the model needs.
