Changes to Glean Assistant: Retiring datasource filtering and source removal

Posted: November 5, 2025

Two features in Glean Assistant will no longer be available after December 2, 2025. These are the ability to filter specific sources in chat and the option to remove sources from existing Assistant responses. These features are being removed to streamline the user experience and because the latest generation of Glean Assistant, powered by advanced LLMs like GPT-5 and Claude Sonnet 4.5, now provides more accurate, context-aware answers without requiring manual source selection.

Users can simply describe what they need in natural language—including whether it should focus on or exclude a specific data source—and Assistant will automatically execute. Users can continue to filter specific sources in search. (Glean ID: ROAD-938)

Sunset date: December 2, 2025

Filtering specific sources in chat will no longer be available starting on December 2, 2025. Instead, users can just ask Assistant to focus on specific sources if desired.
