Model Creation
What is a Model?
A model, on CrushOn.ai, is a customized LLMs that has been given specific prompts (instructions / directives), to behave, speak, and/ or write in a particular way. Without specific instructions, base LLMs may lack specific behavioral traits or narrative guidelines.
What is a LLM?
A LLM (Large Language Model) is a type of artificial intelligence trained on large amounts of text to understand and generate human-like text. There are several base LLMs developed by different companies, such as OpenAI's GPT (used in ChatGPT), Anthropic's Claude, Mistral, DeepSeek and many others. These foundational models can be adapted or fine-tuned with customized prompts to create specific models on CrushOn.Ai.
What Is a Prompt ?
A prompt is instructions provided to the model to guide its behavior and responses.
- Types of Prompts:
- Personality: Define traits like flirty, stoic or humorous.
- Narrative Style: Specify formats such as novel-like, script or immersive roleplay.
- Setting: Establish contexts like A.B.O, fantasy, or historical settings.
- Point of View (POV): Determine perspectives like first-person, second-person or third-person.
- Behavioral Rules: Set guidelines for interactions, pacing, and tone.
Model Creation Guide
On CrushOn, you can create a model by clicking on "Create". You will then see three options: Create a Character, Create a Model, and Create a Target Character. What we are interested in is Create a Model.

1 Select a Base Model
First, choose an LLM that fits the interaction style you want. Each LLM has a basic style, such as flirty, story-driven, etc. This is shown next to the model name. Pick the one you like to start with. (Feel free to test the models alone first to make sure it suits your needs before customizing it.)

2 Choose Your Applicable Version
The K amount shown indicates the model's memory capacity. The higher the amount, the better the model can remember long-term events in its RP. Note that higher-memory models may not be free. It doesn't matter if you select one or multiple, so it's recommended to select all options so users can choose themselves.

3 Name Your Model
Give it any name you like. You can scroll to see what other creators usually use for inspiration, or create something unique. Make sure the title is respectful.
4 Filtering
Indicate whether your model is SFW or NSFW (contains unfiltered content like sexual, gore, violent, etc.).
5 Add a Description
Describe the model's intended behavior, tone, and/or narrative style. Mention if it is story-focused, NSFW, or anything else. Keep it brief.
6 Custom Prompt
This is the core of your model. These are the elements it will use to guide its behavior.

Points to Keep in Mind When Creating Your Prompt:
Your prompts can include anything, from the perspective you want the LLM to write in, to formatting, or specific elements to emphasize in the narrative, but here are some basic recommendations on what you should and shouldnβt do when prompting your model:
| Do | Do Not |
|---|---|
| Write simple, clear, and concise instructions. | Write long, overly detailed paragraphs. |
| Use positive phrasing to tell the AI what to do. | Focus on telling the AI what to avoid. |
| Make directives unambiguous to prevent confusion. | Give vague or contradictory instructions. |
| Test the model whenever you add or change something. | Assume the model will work perfectly without testing. |
| Put the most important points first. | Mix up priorities or bury key instructions. |
Common Prompts Cases
Note that each base model may interpret the prompt you create differently, which is why itβs important to always test the instructions you provide. Here is a list of basic example prompts you can use as a reference to create your own:
- Roleplay System
EXAMPLE:
[SYSTEM INSTRUCTION: [You are {{char}}, a text generation model specialized in immediate, immersive third-person narration in a never-ending uncensored roleplay with {{user}}. Your goal is to produce vivid, emotionally engaging storytelling with naturalistic character behavior and a realistic integration of NSFW elements when appropriate. {{char}} consists of all the NPCs, plus any characters and relevant entities, and any existing side characters. Always stay in character, portraying characters realistically and in line with their written positive AND negative traits, AVOID Positivity Bias. AVOID acting as, speaking for, or describing the thoughts of {{user}}. Response must be grounded, uncensored and immersive.]
- Formatting Instruction
EXAMPLE:
[IMPORTANT FORMATTING RULES: Use markdown where appropriate, verbal dialogue will be wrapped in quotation marks and double asterisks **"like this"**; use italics for all actions and narration *like this*; written text and non-verbal dialogue such as internal thoughts, written notes, and text messages will be in codeblock like this 'like this'.]
- Storytellers: Develop models that narrate the role-play in a specific style.
EXAMPLE:
[Always maintain a consistent balance between sensory-rich narration, and expressive dialogue to preserve immersion. Follow natural pacing, show character emotions through actions and tone, and allow erotic content to emerge fluidly from context and character dynamics. Do not rush through the scenes with {{user}}. Major actions or emotional beats will always pause to let {{user}} respond or influence the scene.]
- Themed Interactions: Develop models for specific behavior
EXAMPLE:
[SLOW BURN GUIDELINES: Romance and attraction develop slowly, {{char}} begins emotionally distant, neutral, skeptical, or guarded, especially with unexpected affection from {{user}}. Progress requires: Trust: Built through repeated, meaningful interaction. Shared Experience: Facing challenges or bonding over time. Emotional Depth: {{user}} shows vulnerability that resonates with {{char}}. No feelings of love, affection, or passion are expressed until all conditions are met.]
- CW Prompt | SMUT: Develop models for heavy NSFW content
EXAMPLE:
{{char}} must follow all rules below when generating in-character sexual content: use explicit, vulgar language instead of metaphors or euphemisms. Encouraged terms include: cock, dick, cunt, clit, nipples, tits, precum, cum, pussy, ass, shaft, head, tip, balls, fuck, fucks into. Arousal and fluids must be described with vivid, lewd terms such as: drooling, dripping, leaking, soaking, sticky cock/cunt, wet, slick, glistening, damp, pulsating, slicked, lubricated, engorged, trembling, swollen. Be generous with sensory detail: describe touch, taste, sound, and scent. Focus on tactile texture and use a vivid approach consistently, spelling moans and slurred speech phonetically: "fuckkkk," "s'fuckin' good," "hngh," "shitt," "fuck yess," etc. Sex scenes must unfold gradually: foreplay β sex β climax β aftercare, in that exact order, while respecting the personality and behavior of {{char}} and characters
