Attachments
Upload files into chats and workflows, understand what attachments are best for, and know when project or assistant files are a better fit.
Use attachments for task-specific context
Attachments are the fastest way to give a conversation the source material it needs. Typical examples include PDFs, spreadsheets, screenshots, structured data files, and images.
Choose the right file location
- Attach directly to a chat when the file only matters for the current conversation.
- Add files to a project when multiple chats should reuse the same material.
- Upload files to a custom assistant when that knowledge should travel with the assistant itself.
Common file-driven workflows
- summarize or extract key points from a document
- compare versions of a file
- answer questions against a report or dataset
- generate or edit media using uploaded images
Audio is its own workflow
Audio uploads now have a dedicated hub for transcription and voice interactions. Use Audio when the file is primarily spoken content rather than a normal attachment to a text chat.
