ChatGPT can now remember your uploaded files across conversations

File limits, referencing, and plan requirements

You can upload files up to 512MB each (per-file limit), with special limits for images (20MB) and spreadsheets (around 50MB, depending on content).
Files remain in your Library until you delete them. If you delete a file, it is removed from the account immediately and will be permanently erased from systems within 30 days.
Referencing is easy: just ask ChatGPT about "yesterday's document" or pick from recent uploads.
Generated images continue to appear in the Images tab; full Library access is included with Plus ($20/month), Pro ($200/month), or Business plans.

No more digging around for old uploads

ChatGPT's Library keeps your stuff organized and searchable across chats: no more digging around or re-uploading the same file.
This update makes working with AI smoother and a lot less hassle.
