Open Generator
Standard NSFW Negative Prompt (always include):
(worst quality, low quality, normal quality:1.4), (deformed, distorted, disfigured:1.3), extra limbs, missing limbs, mutated hands, bad anatomy, bad proportions, text, watermark, signature, blurry, jpeg artifacts, child, minor, underage, loli, shota, multiple heads, fused fingers

For Pony / Illustrious add:
score_1, score_2, score_3, score_4_up, monochrome, 3d, render, source_furry

Pro tip: The `child, minor, underage, loli, shota` tags in the negative prompt are mandatory baseline safety regardless of your positive prompt. Team AIGN includes them on every published prompt. See our methodology page for our editorial standards.

How the NSFW prompt generator works

This tool generates five prompt variants from your scene selections. Each variant uses a different structural pattern (dense ordered, subject emphasis, cinematic setting, close-up, full body) so you can see which structure produces the best output on your model.

The quality tags and camera specs auto-adjust based on the target model you pick. SDXL and SD 1.5 get masterpiece-style quality boosters. Pony Diffusion XL and Illustrious XL get the Booru score_9 score_8_up score_7_up prefix tags they actually need to perform. Flux Dev and Flux Schnell get natural-language quality language and Sony A7R4 camera specs that match how Flux understands prompts best.

When to use which variant

  • Variant 1 (Dense ordered): The default. Good baseline for any model.
  • Variant 2 (Subject emphasis): Use when the subject is getting lost in the background. The (:1.1) and (:1.15) weights pull focus back.
  • Variant 3 (Cinematic setting): Use for storytelling shots where the environment matters as much as the subject.
  • Variant 4 (Close-up portrait): Best for character studies, expression-focused output, headshots.
  • Variant 5 (Full body wide): Best when you need the whole figure plus environment, common for OnlyFans-style preview shots.

Why the negative prompt matters

The negative prompt shown below the generator is mandatory baseline safety regardless of what you put in the positive prompt. The tags child, minor, underage, loli, shota instruct the model to never generate underage subjects. Team AIGN includes these on every published prompt and recommends every reader do the same. Read our methodology page for the full editorial standards.

Model-specific notes

  • SDXL and SD 1.5: Token limit is 75 (SD 1.5) or 150 (SDXL). Variants 1-4 stay within these. Variant 5 (full body) may exceed SD 1.5; truncate the mood modifiers if needed.
  • Pony Diffusion XL: Requires the score_9 score_8_up score_7_up prefix and Booru tag style. German and natural-language adjectives mostly get ignored. The generator adapts automatically when you select Pony.
  • Illustrious XL: Similar to Pony. Booru tags dominate. Best for anime-style output.
  • Flux Dev / Schnell: Natural language works best. Long detailed prompts (100-200 words) produce best results. Camera specs and lens references are interpreted literally.

Frequently asked questions

Is this tool free?

Yes. No login, no email, no rate limit. Runs entirely in your browser. We do not log or store your selections.

Can I use these prompts commercially?

Prompts themselves are not copyrightable. The images you generate are subject to the license of the model you use. Most open-weight Stable Diffusion checkpoints allow commercial use. Always verify the specific model’s license on Civitai or Hugging Face.

Why are my generated images different from what the prompt describes?

Three common causes: (1) Your checkpoint does not know certain concepts. Switch to a checkpoint trained on the target style. (2) Your CFG scale is too low or too high. Try 7-9 for SDXL, 5-7 for Pony. (3) You skipped the negative prompt. Add the standard one shown below the generator.

What models work best with which variant?

From our internal testing: SDXL responds best to Variants 1 and 2. Pony Diffusion XL prefers Variants 1 and 4. Illustrious XL works best with Variant 4 for character-focused output. Flux Dev produces best results with Variant 3 due to its natural-language understanding.

Where do I run these prompts?

Use our free browser-based generator with no login. Or run them locally in ComfyUI, Stable Diffusion Forge, or AUTOMATIC1111. Or use a cloud GPU on RunPod or Vast.ai.
