Compression while creating messages

I was reading on this page: https://platform.openai.com/docs/guides/error-codes/python-library-error-types

In the BadRequestError section:
" * Check the encoding, format, or size of your request data and make sure they are compatible with our services. You may need to encode your data in UTF-8, format your data in JSON, or compress your data if it is too large."

I’ve failed to find out how this “compress your data” is done. Has anyone successfully done this? I’m also using the Python Library.

Welcome to the community!

I imagine they’re talking about images or audio, that can get pretty large if using the wrong compression format.

What are you specifically concerned with, or what isn’t working for you?

Thanks. Was just checking if that was referring to some sort of compression mechanism for large amount of text so as to not hit character limits (during creating messages, creating runs or submitting tool outputs)
