Davinci: How to Write a Good Body Prompt (and What to Avoid)Updated 8 days ago

Draw Me Bot Davinci Model  is designed to generate clean, minimalist, plotter-safe line drawings. When you add a custom body prompt, the wording you choose has a direct impact on how the AI behaves and how consistent, readable, and reliable the final drawing will be.

This guide explains:

  • How to write a good body prompt

  • What to avoid and why

  • What can happen when prompts are poorly written

  • Best practices when using selection screens and personalization

What a Body Prompt Does in Draw Me Bot

The body prompt controls:

  • The pose and action of the character

  • The scene or setting

  • How complex the drawing becomes

Because Draw Me Bot is optimized for monoline, low-detail drawings, the body prompt must support that goal. When it doesn’t, the AI may attempt multiple interpretations internally, which can lead to unstable or unexpected results.

1. Avoid Mixing Realism With Line Art

What to avoid

Do not include:

  • Ultra-realistic

  • High detail

  • Photorealistic

Why this causes problems

These instructions directly contradict the goal. When the AI receives conflicting goals, it may:

  • Try multiple internal solutions

  • Produce repeated or near-identical drawings

  • Reduce consistency between generations

What this can cause

  • Duplicated-looking results

  • Slight pose or layout variations

  • Loss of predictability

2. Avoid Overly Complex Scenes

What to avoid

Body prompts that include:

  • Many props

  • Busy real-world environments

  • Unrelated background events

Why this causes problems

Complex scenes force the AI to decide:

  • Where each object goes

  • How large it should be

  • How it fits the body pose

This increases ambiguity and often leads to multiple internal interpretations.

What this can cause

  • Repeated or tiled outputs

  • Inconsistent layouts

  • Overcrowded drawings that are not plotter-friendly

3. Avoid Ambiguous or Optional Language

What to avoid

Phrases such as:

  • “Include something like…”

  • “Action or setting”

  • “Could be…”

Why this causes problems

Ambiguous wording invites interpretation.
Interpretation leads to branching, and branching leads to inconsistent results.

Better phrasing

Use clear, decisive language:

  • “Depict a single scene where…”

  • “The character is shown…”

Example for a bad results caused by contridicting phrases all at once: 


4. Best Practice When Using Selection Screens

If you are using a selection screen that automatically builds the body prompt, treat the prompt as modular.

After the generated body prompt, add:

“Add a relevant background.”

Why this works well

  • The AI automatically infers a fitting background from the selected theme

  • Each selection gets a matching environment without hardcoding it

  • Prompts stay short, flexible, and consistent

  • Drawings remain clean and plotter-friendly

Draw Me Bot produces better results when personalization data is connected to the body prompt.

Good personalization sources

  • Short surveys

  • Selection Screens

  • Non Linear Workflows

Important Rule for Personalization

Personalization should describe:

  • Role

  • Mood

  • Identity

Avoid using personalization to add:

  • Extra props

  • Complex scenes

  • Detailed environments

Summary: What to Avoid in Draw Me Bot Body Prompts

Avoid:

  • Mixing realism with line-art constraints

  • Overly complex scenes

  • Contradictory detail levels

  • Ambiguous language

  • Too many hard constraints at once
