How to Write Prompts That Work

For Flux and Realistic Vision (Natural Language)

AI models understand English much better than other languages. Write in English even if your grammar is not perfect. Here is a basic template that works for Flux and Realistic Vision:

Positive prompt: a [style] photo of a [age] year old woman, [ethnicity], [hair], [eyes], [body type], [pose], [environment], [lighting], detailed skin texture, photorealistic, 8k, professional photography, perfect anatomy

Negative prompt: deformed, mutated, extra limbs, fused fingers, missing fingers, asymmetric, blurry, lowres, watermark

For Pony and NoobAI (Tag Format)

These models use a tag-based format popular in anime communities:

Positive prompt: score_9, score_8_up, score_7_up, 1girl, [age] years old, [ethnicity], [hair], [eyes], [body type], [pose], [environment], detailed, masterpiece, best quality

Settings: CFG between 5 and 7. Steps between 25 and 40. Sampler DPM++ 2M Karras works universally. Check our realism guide for advanced templates.

Supercharge Quality with LoRAs

For photorealistic results, combine 3 LoRAs in the same prompt:

First: A skin detail LoRA (search skin detail on Civitai, pick one with 3,000+ downloads) with weight 0.6 to 0.8.

Second: A cinematic lighting LoRA (search cinematic lighting on Civitai) with weight 0.4 to 0.6.

Third: An optional style LoRA if you want a specific aesthetic (90s, editorial, vintage) with weight 0.3 to 0.5.

The syntax for Pony XL is . Stack all 3 at the beginning of your prompt. Watch the total weight: the sum of all weights should not exceed 2.0 or the image becomes oversaturated. For adult scenes, avoid weights above 0.9 on the main LoRA because it will dominate the composition. Test with an x/y plot varying weight from 0.3 to 1.0 in 0.1 increments to calibrate for your needs.

Fix Faces and Hands Automatically

Realistic nudes need extra attention to faces and hands. Use ADetailer for automatic fixes:

Face: Use model face_yolov8s.pt (larger than the basic version, more precise) with denoise 0.4.

Hands: Use hand_yolov8n.pt with denoise 0.5 and padding 48 pixels.

Eyes: Use ADetailer Eye Mesh with denoise 0.3 (higher values distort the iris).

These three passes in sequence raise realism by about 40 percent compared to raw checkpoint output. The difference between amateur and professional results often comes down to these automatic fixes.

Legal and Ethical Guidelines

What Is Legal and Ethical

Generating fictional characters you invented is legal and ethical. You created someone who never existed with features you chose. No harm to anyone. Use for personal fantasy, artistic projects, or monetized content on Patreon, OnlyFans celebrity ai nudes with AI personas, or stock image sites. All good.

Absolute Red Lines

Never use a real person’s face without explicit written consent. Law 14.811/24 criminalizes intimate deepfakes with prison sentences. Never generate content involving minors. Any age below 18 in any country is a serious crime in all circumstances. Never use AI nudes to defame, blackmail, or expose someone. These three points have no exceptions, no excuses, no gray zones.

Ethical Safeguards for 2026

• Never train LoRA with a real person’s face without written consent
• Always use tags adult and mature and specify age 25 years old in prompts
• Use invisible watermarking with SteganoGAN as professional practice
• Archive the original prompt with the final image for traceability

These practices protect you and the entire ecosystem. Check ai celebrity nudes our general uncensored AI guide for more legal details.

Undress AI vs Nude AI: Know the Difference

Undress AI takes an existing clothed photo and removes clothing via inpainting. It needs a source photo of a real person. Nude AI generates a naked body from scratch using only text prompts. No source photo needed. This guide focuses on generation from scratch with fictional characters you create.

The two use different models and have different legal aspects. For existing photos, see our undress AI guide. For creating original characters, continue reading.

Frequently Asked Questions

Is generating fictional nudes legal?

Yes. For fictional characters you create from scratch, it is legal. Criminal law and internet civil rights protect adult content production between consenting adults. What is illegal: using a real person’s face without consent (Law 14.811/24 on intimate deepfakes), generating content involving minors (absolutely forbidden), or using it to defame someone. Original fictional character generation with invented features is legal for personal and even commercial use with the correct model license.

Can I use a real person as reference?

No. This is deepfake and it is a crime. Law 14.811/24 explicitly criminalizes producing and sharing synthetic intimate images without consent. Even if you do not publish, having the file on your phone can cause legal problems. Generate fictional characters instead. Describe features like hair, eyes, ethnicity, and adult age in the prompt. The AI creates from scratch. The result is equally beautiful and 100 percent legal.

What is the best model for photorealism in 2026?

Flux Dev with realistic LoRAs is the absolute top for photorealism. Pony Diffusion V6 XL and NoobAI XL are simpler to use and deliver excellent semi-realistic and anime results. Realistic Vision V6 and epicRealism are intermediate options with smaller learning curves. To start without installing anything, use our free generator which already runs Flux NSFW.

How much does it cost to start?

Local with RTX 3060 12GB: zero recurring cost, only electricity (~$5-10/month heavy use). RunPod rental: ~$0.40/hour, ~50 images/hour, about $0.007 per image. Replicate API Flux Schnell: $0.003 per image. Mage.Space Pro: $15/month for unlimited generation in normal queue. Promptchan Free: free with 30 second cooldown between images. The cheapest long-term setup is local hardware after the initial purchase.

What is the complete negative prompt?

bad anatomy, deformed, mutated, extra limbs, fused fingers, missing fingers, asymmetric, blurry, lowres. Set CFG between 5 and 7. Steps between 25 and 40. Sampler DPM++ 2M Karras works universally. Use ADetailer to automatically fix hands and faces. Generate at base resolution 1024 by 1536 (not 512 by 768). For anatomy details, check our anal AI guide.

Can I generate pin-up style nudes?

Yes. On Civitai, search for checkpoints with tags: pin-up, glamour, boudoir, retro pin-up, fashion photography. Realistic Vision V6 and Juggernaut XL are excellent bases for this style. Combine with specific LoRAs like Vintage Pin-up LoRA or Glamour Studio Lighting LoRA. For stylized anime pin-up, use Illustrious XL with pin-up pose LoRAs. Check our anime and hentai guide.

Can I sell AI nudes commercially?

Depends on the model license. Stable Diffusion XL, Flux Dev, and Illustrious allow commercial use without restrictions. Pony V6 XL has a Fair AI Public license that requires credit (mention Pony Diffusion V6 XL in your product description). Always check the license on the model’s Civitai or Hugging Face page. For large-scale sales like NFTs, stock images, or Patreon content, use permissive license models and keep records of which checkpoint generated each image.
