File Upload

Upload and analyze local files in Glean Chat with support for documents, spreadsheets, presentations, and code files

File Upload enables users to upload and analyze local files directly in Glean Assistant, Public Knowledge, and Apps. This feature allows users to query, summarize, and generate content from uploaded files. The upload limits vary based on the model used in your Glean instance.

Security and Privacy

• Files are parsed and scanned for malware before storage
• Malware-infected files trigger upload errors

Privacy Features

• Uploaded files are only accessible to the uploading user

Upload Limits

The maximum file size and number of files allowed per session depends on your model:

Model	File Limit	Size Limit
128K Models	5 files	64 MB
32K Models	4 files	32 MB
8K Models	2 files	16 MB

Known Limitations

• Multi-media support for video and audio files is not available. Files outside of the supported file types above cannot be uploaded.
• Custom data retention policies for file uploads are not supported beyond your configured chat history retention. You can ask users to disable chat session history or to manually delete chat sessions if you would like to delete files and metadata sooner.
• Optical Character Recognition (OCR) must be enabled for scanned PDFs to work properly - contact Glean support if you experience issues
