Generating AI art is easy. Controlling it is hard.

If you want to move from "Lucky Accidents" to "Professional Design," you need to master Parameters. These are the secret codes you add to the end of your prompt.


1. Aspect Ratio (--ar)

Change the shape of your image. Default is square (1:1).

--ar 16:9 (YouTube Thumbnails)
--ar 9:16 (TikTok/Pinterest)
--ar 2:3 (Posters/Print)

2. Stylize (--s)

Controls how "Artistic" the AI gets. Range is 0 to 1000.

  • --s 0: Follows your prompt literally (stiff).
  • --s 100: Default balance.
  • --s 750: Highly artistic, but might ignore parts of your prompt.

3. Weirdness (--w)

Want something unique? This parameter introduces strange, unexpected elements.

/imagine prompt: a cat eating pizza --w 500

4. Negative Prompts (--no)

Tell the AI what to remove from the image.

Example: You want a clean portrait without glasses.

--no glasses, text, blurry, watermark
