Midjourney Parameters

--ar (Aspect Ratio)
  Sets the width-to-height ratio of the output image.
  Default: 1:1
  Examples: --ar 16:9, --ar 2:3, --ar 9:16, --ar 4:5

--v (Version)
  Selects the Midjourney model version.
  Examples: --v 5, --v 5.2, --v 6

--stylize or --s (Stylization)
  Controls how strongly Midjourney's aesthetic is applied.
  Range: 0-1000 (default: 100)
  Low (0-50): More literal, less artistic
  Default (100): Balanced
  High (250-750): Very artistic, may diverge from prompt

--chaos or --c (Chaos)
  Controls variation between the 4 images in a grid.
  Range: 0-100 (default: 0)
  Low: All 4 images are similar
  High: All 4 images are very different

--no (Negative Prompt)
  Excludes specified elements from the image.
  Example: --no text, watermark, frame

--seed
  Sets the random seed for reproducible results.
  Range: 0-4294967295
  Same seed + same prompt = same image

--tile
  Creates seamlessly tileable patterns.
  Great for textures, wallpapers, and backgrounds.
  Example: /imagine brick wall texture --tile

--style
  Switches between style sub-versions.
  --style raw: Less opinionated, more literal
  Example: /imagine mountain landscape --style raw

--q (Quality)
  Controls rendering quality and generation time.
  Values: .25, .5, 1 (default: 1)
  Lower = faster but less detail

--repeat or --r
  Runs the same prompt multiple times.
  Example: --r 4 (generates 4 separate grids)

--w and --h (Niji model only)
  Set specific width and height in pixels.
