Hi @colin.g.prince2
Welcome to the community!
I just tested, and there is no problem on my end.
But, I experienced in the past, too.
Some probabilities:
- Network problem (but it should give error as ‘File upload fail.’)
- VPN
- Some extensions or plugins on the browser.
- There could be a bug on ChatGPT at that moment, so check the Status of OpenAI
- Some files uploaded before this file, and storage is full, more than 20 files (limit 20 files)
- The file size problem. The maximum file size is 512 MB. Each file should contain no more than 5,000,000 tokens per file (computed automatically when you attach a file).
- On GPT builder, if you try to update GPT, before file completely uploaded. In the image below, sample1.pdf gives error if we force to update on GPT Builder.
I used some workarounds:
First log out from all devices, then sign in from only one device.
1- When I want to create a custom GPT or upload files, I use another browser that does not have any extensions or plugins. And it works generally.
2- I upload files to Google Drive or Icloud, I launch ChatGPT on my mobile phone using a browser like Google Chrome. I copy paste everything from clouds, and upload files. I never faced with a problem on the phone when creating custom GPT or uploading files.
