Create upload

POSThttps://api.openai.com/v1/uploads

Creates an intermediate Upload object that you can add Parts to. Currently, an Upload can accept at most 8 GB in total and expires after an hour after you create it.

Once you complete the Upload, we will create a File object that contains all the parts you uploaded. This File is usable in the rest of our platform as a regular File object.

For certain purposes, the correct mime_type must be specified. Please refer to documentation for the supported MIME types for your use case:

For guidance on the proper filename extensions for each purpose, please follow the documentation on creating a File.
