Deep Research

Deep Research is an AI agent that generates detailed, citation-rich reports by synthesizing information from your internal enterprise systems and the web. It's built for complex, multi-source questions—such as strategic planning, competitive analysis, and research—rather than quick fact lookups. This page covers how to turn Deep Research on or off and the key details admins should know. For end-user instructions, see Deep Research.

Enable or disable Deep Research​

You can enable or disable Deep Research for your organization or specific users in the Admin Console:

  1. Navigate to Admin Console → Platform → Assistant → Settings.
  2. Expand the Deep Research section.
  3. Select one of the following:
    • On for everyone (recommended if Glean is enabled)
    • On for some users (test group via allowlist)
    • Off (disable for everyone)
  4. Select Save.

Once enabled, Deep Research appears as a reasoning mode in the chat input. It is currently available on the Glean web application only.

How Deep Research works​

  • Sources: Deep Research searches your connected enterprise systems and the web, then synthesizes the results into a structured report with fully linked citations. Web content is retrieved through Brave Web Search.
  • Model: Reports are generated using GPT-5.1 as the reasoning model.
  • Permissions: Deep Research respects each user's existing document permissions and only retrieves content the user is already allowed to see.
  • Read-only: Deep Research does not run actions or MCP tools in connected apps. Users who need actions should use Thinking mode in standard chat instead.
  • Report length and time: A typical report spans 5–10 pages and takes 5–30 minutes to generate, depending on query complexity and the number of sources.

LLM key support​

Deep Research supports the Glean Universal Key and Customer Key (BYOK). With a Customer Key, Deep Research supports all available models (GPT-5, GPT-5.1, Claude Sonnet 4.5, and Gemini Pro 3) across all supported providers (Azure OpenAI, AWS Bedrock, and Google Vertex AI). See Bring Your Own Key (BYOK) and Feature availability by LLM key, provider, and cloud.

Usage and billing​

On Glean Enterprise Flex, each Deep Research report generation consumes FlexCredits at the current rate card. Because reports are more compute-intensive than standard chat, consider starting with an allowlist before enabling Deep Research for everyone. See Glean Enterprise Flex for details.
