When Will ChatGPT API File Upload Feature Be Available?

The file upload capability for document analysis is mentioned as coming soon via the ChatGPT API. Could you provide an estimated timeline or update on when this feature will be available through the API?

The web version of ChatGPT has a feature that allows you to upload and analyze files. From what I understand, the process involves uploading files, obtaining a file_id, and then including that file_id in the conversation to perform document analysis. However, after thoroughly reviewing the API documentation, I found no similar method. How can I achieve this?

The chat method in the API doesn’t include any file_id, although it supports file uploads. I see that apart from using the assistant method for analysis, there is no other way to achieve this functionality. But the assistant method has a limitation where the company is capped at 100GB. If I limit users to uploading files of 20MB, this would only support around 5000 users, which is too few for my needs. Are there any better solutions?
