What Are the File Size and Count Limits and How Are Sources Referenced in Assistant Uploads?

Below are the answers based on the documentation:

1. Limits on File Uploads and Charging

• File Size Limits:

  • The file upload endpoint lets you upload files up to 512 MB each.
  • The total size of all files uploaded by a single organization is limited to 100 GB.
  • Additionally, for certain endpoints (for example, attachments to assistants), there is a maximum of 20 files per assistant.
  • When using the Assistants API for file uploads (such as for fine-tuning or batch processes), note that there may be further restrictions. For instance, the Assistants API supports files up to 2 million tokens and specific file types, and the Batch API accepts only .jsonl files up to 200 MB with a required format.

• Charging Model:

  • File uploads are handled as part of the API usage. They are not charged in the same way as embeddings (which are billed per compute or usage unit).
  • The documentation does not specify separate pricing for file uploads—it falls under the general usage of the API. For exact details on billing, you should consult the official OpenAI pricing page or your account usage details.

2. Source References and How to Access Them

• The references you see (for example, the notation like [24†source]) indicate that the assistant’s answer is based on internal, aggregated documentation covering the OpenAI API and Assistant UI tools.
• These internal reference pointers are used to help track which parts of the documentation the answer is based on, but they are not linked to separate, publicly accessible files.
• To verify or explore this information further, please refer to the official documentation:
  • OpenAI API documentation
  • Assistant UI documentation and guides
