Stable Diffusion is a powerful AI art generation model that can create stunning images from text descriptions. This guide will help you get started with the basics of generating AI art.

What is Stable Diffusion?

Stable Diffusion is an AI model that converts text descriptions (prompts) into images. It understands both simple descriptions and artistic concepts, allowing you to create a wide range of visual content.

Getting Started

The easiest way to start is using Thunder Compute’s pre-configured environment:

  1. Visit Thunder Compute
  2. Create an account if you haven’t already
  3. Select the “ComfyUI” template
  4. Launch your instance

You’ll get instant access to:

  • Pre-installed ComfyUI editor for Stable Diffusion
  • Optimized GPU settings
  • No setup or driver installation required

Run start-comfyui in the terminal to start the ComfyUI editor. Access your workspace through the provided URL and you’re ready to start generating images!

Option 2: Local Setup

Requirements:

  • NVIDIA GPU with 8GB+ VRAM
  • 16GB+ RAM
  • 50GB+ free storage

Writing Effective Prompts

Good prompts are key to getting the results you want. Here’s a basic structure:

[subject], [setting/environment], [style], [lighting], [camera angle]

Examples:

  • “A serene mountain lake at sunset, professional photography, golden hour lighting”
  • “A cute red panda in a bamboo forest, Studio Ghibli style, soft lighting”

Tips for Better Results

  1. Be Specific
    • Instead of “a house”, try “a Victorian mansion with wraparound porch”
    • Add details about lighting, mood, and style
  2. Use Style Keywords
    • “digital art”
    • “oil painting”
    • “photorealistic”
    • “watercolor”
  3. Quality Boosters
    • “high quality”
    • “detailed”
    • “masterpiece”
    • “professional”

Basic Settings

Key parameters to adjust:

  1. CFG Scale (7-12)
    • Lower: More creative but less accurate
    • Higher: More precise but can be rigid
  2. Steps (20-40)
    • More steps = more detailed results
    • Diminishing returns after 40
  3. Seed
    • Save seeds you like for consistency
    • Change seeds for variation

Common Issues and Solutions

  1. Blurry Images
    • Increase step count
    • Add “highly detailed” to prompt
    • Adjust CFG scale up slightly
  2. Unrealistic Results
    • Add “photorealistic” to prompt
    • Use “professional photography” style
    • Reduce creativity in settings
  3. Wrong Compositions
    • Be more specific about layout
    • Use directional terms (foreground, background)
    • Specify camera angles
