Create File

Go to Product

Upload a file that can be used across various endpoints. Individual files can be up to 512 MB, and each project can store up to 2.5 TB of files in total. There is no organization-wide storage limit. Uploads to this endpoint are rate-limited to 1,000 requests per minute per authenticated user.

  • The Assistants API supports files up to 2 million tokens and of specific file types. See the Assistants Tools guide for details.
  • The Fine-tuning API only supports .jsonl files. The input also has certain required formats for fine-tuning chat or completions models.
  • The Batch API only supports .jsonl files up to 200 MB in size. The input also has a specific required format.
  • For Retrieval or file_search ingestion, upload files here first. If you need to attach multiple uploaded files to the same vector store, use /vector_stores/{vector_store_id}/file_batches instead of attaching them one by one. Vector store attachment has separate limits from file upload, including 2,000 attached files per minute per organization.

Please contact us if you need to increase these storage limits.
