Imagery: a stylised stack of three offset rectangles, simple and bold with a single focal shape.

Constraints: no host photos, no logos, no subtitles, no small text, no borders.

A square artwork with GROWTH STACK in heavy condensed type, three offset rectangles in orange and indigo, readable when reduced to a thumbnail.

Expected format: One square image; test at 150px.

How to use it

  1. Shrink to about 150px to test legibility.
  2. Keep the title to a few words.
  3. Export at the largest size your podcast host requires and check their rules.

Limitations

  • Podcast directories have their own size and content requirements; check them.
  • Small text will not survive thumbnail sizes, so do not add any.

Aspect ratio is set with the size parameter, not in prose. Use medium or high quality for text and fine detail. Quote the literal text and describe typography as constraints; OpenAI and Google both document this pattern. Always proofread the result.

General notes on OpenAI GPT Image
  • OpenAI's guide covers gpt-image-2 (recommended), gpt-image-1.5, gpt-image-1 and gpt-image-1-mini.
  • Aspect ratio is set through the size parameter, not in prose. Quality is low, medium or high; medium or high is advised for small or dense text.
  • Put literal text in quotation marks, and when editing say what must stay unchanged.
