Prompt Writing Guide

Master the art of crafting perfect prompts for AI image generation

Prompt Basics

Our AI models work best with natural language prompts that are clear, detailed, and well-structured. The model understands English descriptions and responds to both simple and complex instructions.

Key Principle: Be specific and descriptive. Instead of “woman”, use “young woman with long flowing auburn hair and emerald green eyes”.
  • Use commas to separate concepts and attributes
  • Place the most important elements at the beginning
  • Be descriptive but concise - avoid unnecessary repetition
  • Use natural language rather than keyword stuffing

Prompt Structure

A well-structured prompt typically follows this order:

[Quality Tags] → [Subject] → [Details] → [Action/Pose] → [Clothing/Appearance] → [Setting/Background] → [Lighting/Atmosphere] → [Style/Artist]
Example:
masterpiece, best quality, 1girl, beautiful woman with long silver hair and blue eyes, wearing elegant black dress, standing in moonlit garden, soft rim lighting, cinematic atmosphere

Using Weights & Emphasis

Control the importance of specific elements using parentheses and brackets:

  • (concept) - Increases weight by 1.1x
  • ((concept)) - Increases weight by 1.21x (1.1²)
  • (concept:1.3) - Explicit weight multiplier
  • [concept] - Decreases weight by 0.9x
(beautiful detailed eyes:1.3), ((masterpiece)), [background:0.8]
Warning: Overuse of weights can lead to distorted or unrealistic results. Use sparingly and test different values.

Quality Tags

NSFW Prompting

For adult content, be explicit and detailed about what you want:

Best Practices:
  • Combine quality tags with NSFW descriptors
  • Specify clothing state clearly (nude, topless, lingerie, etc.)
  • Use anatomical precision (breasts, nipples, genitals, etc.)
  • Describe poses and angles for desired composition
  • Add context (bedroom, shower, outdoor, etc.)

Tips & Tricks

💡

Experiment with order: The model gives more weight to elements mentioned earlier in the prompt. Place your most important features first.

🎨

Layer your details: Start broad (subject, pose), then add specifics (clothing, expression), then environment, then lighting/style.

Use artist references: You can reference art styles like “makoto shinkai style” or “studio ghibli” for specific aesthetics.

🔧

Iterate and refine: Start with a basic prompt, generate, then add details based on what's missing or what you want to change.

🚫

Don't over-prompt: Too many tags can confuse the model. Aim for 40-80 words for positive prompts, 20-40 for negative.

📸

Camera terminology works: Use photography terms like “shallow depth of field”, “wide aperture”, “50mm lens” for realistic shots.

Common Mistakes to Avoid

❌ Vague descriptions:
pretty girl
✅ Better:
beautiful woman in her 20s, long wavy blonde hair, bright blue eyes, gentle smile
❌ Keyword stuffing:
beautiful, gorgeous, pretty, attractive, stunning, amazing
✅ Better:
beautiful woman, elegant features
❌ Contradictory prompts:
photorealistic, sketch, cartoon
✅ Better:
Choose one style and stick with it

Moderation Rules & Safety

Kalon Studio uses a dual-layer moderation stack (GPT-OSS Safeguard + OpenAI) to keep the platform safe while still supporting consensual adult creativity. Every generation request, chat message, and character edit is screened against the policy summarized below.

High-level rules:
  • Adults only (18+) - no minors, youth-coded language, or student contexts without explicit adulthood
  • No real people or public figures - stick to original or clearly fictional adults
  • Consent is mandatory - nothing involving coercion, intoxication, blackmail, or force
  • No extreme illegality - bestiality, necrophilia, trafficking, or weapon/drug instructions
  • Violence is allowed when fictional and not fetishized in a harmful way

Always Allowed

  • Original adult characters (fantasy, sci-fi, stylized, realistic)
  • Consensual intimacy, BDSM, kink, and romance between adults
  • Dark fantasy action, horror, and cinematic violence between fictional beings
  • Stylized nudity or boudoir photography references with clear adult context

Always Blocked

  • Minors, teens, students, or young-sounding bodies/faces
  • Named celebrities, influencers, politicians, or public figures
  • Non-consensual scenarios, blackmail, incapacitation, or force
  • Bestiality, necrophilia, or explicit exploitation/trafficking themes

What You Cannot Generate

These requests are automatically rejected. Trying to bypass the filters can lead to account suspension.

Minors & Youth-Coded Language

  • Any reference to ages under 18 (for example: 17, teen, underage)
  • Descriptors like schoolgirl, loli, shota, barely legal, or fresh 18
  • Family roles implying minors (daughter, son) unless clearly stated as adult

Real People & Public Figures

  • Named actors, musicians, politicians, influencers, or athletes
  • Historical figures or current public officials (even in non-NSFW contexts)
  • Look-alike descriptions targeting an identifiable person

Consent & Harm

  • Non-consensual acts, coercion, threats, or drugging
  • Sexualized violence or enjoyment of suffering
  • Detailed instructions for harming yourself or others

Illegal & Extreme Content

  • Bestiality or sexual activity with non-humans/animals
  • Necrophilia or exploitation scenarios
  • Weapon/drug manufacturing instructions or trafficking narratives

Why Prompts Get Flagged

Moderation models look for specific keywords, relationships, and contexts. When a violation occurs, we log the category so you can adjust future prompts.

Minors or youth-coded cues

Words like teen, school uniform, underage, or overly childish descriptors signal a policy break even if you intended an adult. Spell out adult ages instead.

Public figures

Any real person (celebrity, influencer, politician) is blocked outright. Create original characters or use archetypes such as a cyberpunk pop star rather than names.

Consent signals

Phrases such as forced, against her will, drugged, or passed out automatically fail moderation. Reframe scenarios with enthusiastic consent and agency.

Illegal/extreme references

Requests that mention bestiality, necrophilia, trafficking, or weapon/drug instructions cannot be approved. Remove those concepts entirely.

Avoiding Flags While Staying Compliant

Sometimes a prompt is blocked even though you intended a safe, adult scenario. Use these techniques to clarify intent without violating policy.

🧾

State ages explicitly: Add phrases like 25-year-old or in her 30s so the model knows the subject is an adult.

🎓

Rephrase uniforms: Instead of the literal phrase school uniform, describe the garments (tailored navy blazer with pleated skirt, adult fashion runway look) or explicitly note college alum cosplay, age 24.

👥

Clarify consent: Use language like enthusiastic, consenting partners, or confident pose to offset potentially ambiguous cues.

🚫

Avoid public figure hints: Swap celebrity names for style cues such as retro pop diva aesthetic to keep things fictional.

📚

Keep context consistent: Do not mix incompatible tags like photorealistic + cartoon or innocent + explicit - clarity reduces moderation confusion.

If your prompt still triggers moderation, review the violation category in the error toast and revisit this section for compliant rewrites.
