OpenAI has launched the ChatGPT Image Library.
This is currently rolling out to all ChatGPT Free, Plus, and Pro users, and is available on Web and Android/iOS.
Only images created with 4o Image Generation (not from legacy DALL·E) will show up in the Library. We’re currently backfilling all images, so it may take a couple days to see older images.
