Files and attachments

Files attached to a request come along with it. Slack uploads, Linear uploads, ClickUp attachments and files you add in the app’s chat are saved under data/attachments/.

Kind Up to What the model gets
Images (PNG, JPEG, GIF, WebP) 5 MB each, 4 per message The image itself, so a screenshot of an error counts as part of the request.
Text and code files 200 KB The contents, up to 20,000 characters per file.
Anything else (PDFs, archives…) 25 MB The file name and type.

A file over its limit isn’t downloaded, but it’s still listed, so Relay and you can see it was there.

Attachments are treated as data from other people, never as instructions.

A workspace’s Files tab has a view of every file shared in its messages, newest first, with a preview beside it.

Files you add in chat but never send are removed after a day. Files that went out with a message are kept.
