Hidden ChatGPT Library feature stores permanent character references — tested with an aristocratic turnip
thethirstgame · reddit · 2026-10-31
A Reddit user uncovered a hidden ChatGPT feature in the Library that saves permanent image references: upload an image, name it, and file it under Me, Friends, Pets, Spaces, or Other. They created 'Lord Turnip von Baldrick' — monocle, purple coat, blue lightning bolt, one red boot — saved his portrait, then asked a fresh conversation to draw him on a throne. The result preserved every distinctive detail and even showed the original reference thumbnail. Potentially very useful for recurring characters, comics, and consistent environments, though OpenAI offers no documentation. Open questions: whether multiple images can merge into one reference, any limits, whether categories affect retrieval, and whether the system uses the original or a cropped image.
