As of May 21 2025, we’ve added new built-in tools to the Responses API—remote MCP servers, Image Generation, Code Interpreter, and an upgraded File Search—along with background mode and encrypted content, so you can build agents that pull richer context and run more reliably. For details, see our Responses API docs.
OpenAI currently supports a file storage quota of 2.5 TB of files per project. If this quota is breached, you will see the following error:
You have exceeded your file storage quota. Projects are limited to 2.5 TB of files. Please reduce the file size or contact support.We recommend deleting files stored on your account that you no longer need. Some customers implement regular cleanup jobs to help avoid this issue. You can view and list files with the API, then delete files you no longer need. Deleted files are removed from listing immediately, and storage quota may be freed after backend deletion and quota reconciliation complete. If you still need your file storage quota raised, please let us know by starting a conversation on help.openai.com with our help bot.
