Open WebUI Release Notes

Added

• 📉 Far smaller slim image. A slim build now comes down at around 175 MB, near enough 89% smaller than the last release, the local models, the packages around them and the tools that installed them all gone from it; what that changes about the way an instance behaves is set out under Changed below and in the documentation.

• 📦 Smaller standard image. The image no longer carries a second copy of Python, two sets of fonts nothing ever loaded, packages nothing imports, or the tool that installed them, taking about 170 MB off a standard build. #29731, #29723, #29725, #29726, #29728, Commit, Commit, Commit, Commit …

Added

• ♿ Accessibility mode reaches the menus. Accessibility mode now marks the menu entry you are pointing at and the model already chosen with a stronger background, across the dropdown menus, their submenus, and the model picker together with its filter and compare controls, so those cues carry the contrast the accessibility guidelines ask for in both themes.

• 🔄 General improvements. Various improvements were implemented across the application to enhance performance, stability, and security.
• 🌐 Translation updates. Translations for Indonesian were enhanced and expanded.

Fixed

• 💥 Chat branches stay connected after reloads. A reply saved under an earlier message now stays listed under that message, so branch arrows, exports, reloads, and later edits keep the whole conversation in view, and chats already saved with that link missing are repaired when opened. #29299 …

Added

• 🖼️ Richer previews for terminal files. Word documents and slide decks produced in the terminal are now previewed as the finished document rather than an approximation, and every document preview gains a page strip down the side with numbered thumbnails you can click to jump straight to a page, and the notice warning that a preview might differ from the download is gone now that it does not.

• ⚡ Less overhead on every message. Deployments without pipelines configured, which is the default, no longer pay setup work for them on each chat message and background task. #29146
• 🏎️ Lighter model list refreshes. On deployments running several workers, a refresh that finds the model list unchanged no longer has every worker rewrite the whole list to the shared cache, cutting the work and the traffic each refresh costs. #29264 …

Added

• 🚦 Human in the loop tool approval. Where an administrator has turned it on, you can switch a conversation from letting tools run freely to being asked first, so a model that wants to use a tool stops and waits for you to allow or deny it, one call at a time in a saved conversation, by button or by keyboard shortcut, with your choice remembered for this conversation and for future ones, switching back to running freely releasing anything already waiting, and automations, channel replies, and temporary chats unaffected.

Added

• 🎨 Redesigned interface. Open WebUI has been visually rebuilt from the ground up. All aspects of the User Interface, from the chat view to the admin panel. Now with a narrower conversation column, lighter typography, tidier spacing, consistent menus and dropdowns, clearly outlined text boxes, and settings rearranged.
