OpenAI API | Uploads › Parts

The number of bytes uploaded upon completion must match the number of bytes initially specified when creating the Upload object. No Parts may be added after an Upload is completed.

Create Upload ->

Upload

post/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:

Assistants

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