Direct answer
I couldn’t verify a fixed number of uploads or a universal reset period for ChatGPT Free in the official guidance reviewed here. OpenAI says file uploads have separate usage limits, and that ChatGPT notifies you when you reach an applicable limit and shows reset timing in the product. Check the notice in your own account rather than budgeting around a specific daily or weekly count. (ChatGPT Free Tier FAQ)
What to check when planning uploads
- Upload limit: Free-tier file uploads are subject to usage limits. When you reach an applicable limit, ChatGPT provides a notice and shows reset timing in-product. The guidance reviewed here doesn’t establish a fixed upload count. (ChatGPT Free Tier FAQ)
- Storage: The Free Tier FAQ lists 500 MB of Library storage. That is storage capacity, not an upload count; OpenAI says Library storage is separate from daily attachment and chat limits. (ChatGPT Free Tier FAQ; Using Library to manage files in ChatGPT)
- File availability: Documents, spreadsheets, presentations, text files, and images are available on Free subject to plan-specific limits and account settings. (Uploading files and audio to ChatGPT)
Budgeting takeaway: I couldn’t verify a guaranteed number of Free uploads per day or week from the official guidance reviewed here. Use the limit and reset notice shown in ChatGPT, and don’t treat Library storage as an upload-count allowance.
Does the Free upload limit set your production API budget?
No. The ChatGPT Free upload limit doesn’t establish production API capacity or cost. OpenAI documents separate file-upload requirements and limits for the API. API billing is also separate from ChatGPT billing, so estimate production costs from the API models and features you plan to use—not from a ChatGPT Free upload allowance.
