May 2026 — ChatGPT / API Image Gallery, Prompt Tips, and Help: Generative Art Theme: Science

Exactly the same steps as I posted here: Having trouble getting transparent backgrounds in ChatGPT images - #52 by LarisaHaster

This time tho my original prompt was: Ice cream made of colorful diamonds, pink background.

I must say, I am a bit fascinated about this, because when I prompt Remove the pink background completely, transparent PNG, true alpha channel, the output is chessboard background and then lastly I prompted Remove the chessboard background completely. After that I’m able to download the true transparent PNG colorful diamond ice cream. Second time in row, complete success of transparent background.

Could it be session memory?
