**Enter a prompt and tweak your settings:**  
- **Width & Height** – choose your canvas size  
- **Seed** – pick a number or check **Randomize Seed**  
- **Server** – switch between servers if one is slow or fails:
  - **Google US Server**  
  - **Azure Lite Supercomputer Server**  
  - **Artemis GPU Super cluster**  
  - **NebulaDrive Tensor Server**
  - **NSFW‑Core: Uncensored Servers** (for explicit content; use responsibly)
