Files & context
Add only the material you intend to share with the selected model.
Updated October 31, 2026
Selected text files
Attach supported text files explicitly. Upload state reports progress, ready status or a failure. A failed upload is not usable context. Projects can organize related source material without being required for a new chat.
Binary artifacts
PE, ELF and .NET artifacts use a separate quarantined static-analysis path with a 1 MiB limit. Binary bytes are not silently decoded into ordinary text context, and uploading does not execute them.
Removing a source
Removing a source also removes derived responses and reports under the data-handling policy. Review the deletion confirmation and wait for the recorded outcome.
