Custom GPTs can be very useful for all sorts of tasks, and you may want to ask your custom GPT to generate a file such as a data analysis, creative brief, or agenda so that you can share it with others.
Some users find that they run into an error when they try to download a file generated by a custom GPT.
You can resolve this error by enabling the Code Interpreter & Data Analysis tool for the GPT. This will need to be done by the owner of the GPT, or anyone who has edit permissions for the GPT. With this tool enabled, the GPT will be able to generate real files for download.
