Prompt Expansion

When enabled, the model uses an LLM to automatically expand and enhance your prompt for better generation results. This is useful when you have a short or simple prompt and want the model to add more detail.

How to Use

  1. Write your prompt — describe the image including subject, style, lighting, and mood.
  2. Set size — adjust width and height for your desired dimensions.
  3. Set seed — use -1 for random results, or specify a number for reproducibility.
  4. Choose output format — jpeg for smaller files, png for lossless quality.
  5. Enable prompt expansion (optional) — check this to let LLM enhance your prompt automatically.
