In the news
Open WebUI 0.12.0 adds Realtime voice calls and two-factor sign-in
On October 10, 2026 the Open WebUI project published version 0.12.0 on GitHub. The release notes say administrators can switch Call mode from Standard to Realtime, so voice calls go through an OpenAI Realtime voice model that hands questions and tasks to the chat's selected model, and that models can show an animated 3D avatar during Realtime calls. Administrators can also require an authenticator app at sign-in, with single-use recovery codes. The notes further add an Allow replies sharing mode for shared chats and named model controls, such as a Thinking control that sets reasoning effort. USASI has not tested these changes.
Open WebUI 0.11.0 ships a redesigned interface and optional sub-agents
Open WebUI published version 0.11.0 on GitHub on July 27, 2026. The release notes say the interface has been visually rebuilt, from the chat view to the admin panel. They also list sub-agents, which administrators can enable through an
ENABLE_SUBAGENTSsetting so that a model can hand parts of a task to background helper agents that report results back into the chat. Other listed additions include chat forking, chat timers, webhook notification targets, and LDAP group synchronization. USASI has not tested this release.
