• Fast generation Optimized for quick turnaround, ideal for rapid ideation and creative iteration.

Parameters

Output Format Options

• jpeg — Smaller file size, good for photos and web use (default)
• png — Lossless quality, supports transparency, best for graphics

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.
6. Run — click Run, preview the result, and iterate if needed.

Pricing

Simple flat-rate pricing regardless of image size or output format.
