Major Launches
284 new vendor MCP server templates
The MCP server directory now includes 284 new vendor templates spanning legal, finance, real estate, HR and recruiting, marketing, healthcare, security, productivity, and developer tools — including Evernote, DeepL, Tableau Cloud, Meltwater, Coursera, DataCamp, GitBook, draw.io, WeTransfer, Reclaim.ai, Neon, WorkOS, AveryGPT, and Legal Brain Agent for researching Japanese laws, precedents, guidelines, and legal books. Unverified templates are visually separated with caution indicators so admins can make informed choices, and the Ticketmaster template ships disabled pending qualification.
How to access: Admins explicitly add and enable each server from the MCP server directory in the Admin Console; most templates use per-user OAuth.

Search and Chat APIs callable without the experimental header (beta)
POST /api/search, GET /api/search/filters, and POST /api/chat no longer require the X-Glean-Include-Experimental header, simplifying integrations that call these endpoints.
How to access: Available in private beta on a phased basis; contact your Glean account team to participate.
Developer Platform [ROAD-1473]Tableau permissions crawling (beta)
Glean can now crawl Tableau permissions without per-user crawls, keeping Tableau content permissions-aware with less setup.

Connectors [ROAD-1232]Updated left navigation
Glean's left navigation is reorganized into tiers with an overflow menu. Users can customize their own sidebar, and admins can set the default sidebar layout for their organization from Admin Console → Appearance.

Assistant [ROAD-1669]AI & Model Updates
Four new open models in Assistant and Agents
Four open models are now available: GLM-5.3, a premium open model for complex knowledge work and agentic tasks; GLM-5.3 Flash for faster, cost-efficient everyday workflows; Kimi K3 for artifact creation and design-heavy workflows; and DeepSeek V4.1 Flash for fast, highly cost-efficient general knowledge work and agentic use. GLM-5.3 and Kimi K3 are premium models; GLM-5.3 Flash and DeepSeek V4.1 Flash are standard models. GLM-5.3 Flash, DeepSeek V4.1 Flash, and Kimi K3 are the first open models with primary placement in the model picker. All four are served through Glean's US-based inference-hosting providers and follow the regional controls for open models (see manage open models by region).
How to access: For Glean Universal Model Key deployments, go to Admin Console → Models → Other open models, turn on open models trained by Chinese companies, and select Save. Access can also be restricted by department or team, or blocked separately for Assistant or Agents.
