Realtime voice calls. Administrators can now switch Call mode in the Voice calls section of Audio settings from Standard to Realtime, so Voice mode talks through an OpenAI Realtime voice model (gpt-realtime-2.1-mini with the Marin voice by default) that handles small talk itself and hands real questions and tasks to the chat's selected model, with its conversation history and tools, before speaking the answer while the full reply appears in the chat. Approvals and questions from tools still have to be answered in the chat, calls need the Allow Call permission and end after an hour, models can set their own Realtime Voice in the model editor, and the settings can also be given with the "AUDIO_REALTIME_ENABLED", "AUDIO_REALTIME_OPENAI_API_BASE_URL", "AUDIO_REALTIME_OPENAI_API_KEY", "AUDIO_REALTIME_MODEL", "AUDIO_REALTIME_VOICE", "AUDIO_REALTIME_TRANSCRIPTION_MODEL" and "REALTIME_CALL_PROMPT_TEMPLATE" environment variables.

Animated avatars in Realtime voice calls. A model can now show a 3D character instead of the voice orb during Realtime calls: in the model editor, upload a rigged VRM avatar of up to 25 MiB, preview it, optionally give it VRMA clips of up to 10 MiB for its idle, listening and speaking states, and add up to 16 named gestures with a description, which the voice model plays on its own when the conversation fits or when asked, such as a wave or a clap, while the avatar's mouth follows the spoken answer.

Two-factor sign-in. Administrators can require an authenticator app for every user under Admin Settings > Authentication, or with "ENABLE_MFA", so users set one up from a QR code on their next sign-in, get ten single-use recovery codes, and can later replace their authenticator or create new recovery codes in their account settings; OAuth and trusted-header sign-ins can be let through without it with "MFA_ALLOW_OAUTH_BYPASS" and "MFA_ALLOW_TRUSTED_HEADER_BYPASS", and the "open-webui mfa reset" command gives a user who lost their authenticator a one-time recovery token.

Replying in shared chats. When sharing a chat with people or groups, or sharing a folder, the new Sharing mode setting can be switched from Clone only to Allow replies, so everyone it is shared with can keep writing in the same conversation instead of cloning it. Each message shows the name and profile picture of who sent it, with other people's messages on the left in bubble view, replies stream live to everyone with the chat open, a line above the input shows who is typing, people can only edit, rate, regenerate or stop their own messages, and the owner's own chat settings, title and tags stay untouched by others.

Model controls. Anyone who can edit a model can now add named controls to it in the model editor, such as a Thinking control whose Low, Medium and High options each set the reasoning effort, where every option can carry its own custom parameters and one can be marked as the default, shown either as a menu or as a slider that runs from the first option to the last; people with the Allow Chat Controls and Allow Chat Params permissions then pick an option from a knobs button next to the model selector in the chat input, their choice is remembered for that model, and the names of controls and options can be translated for each language in the editor. Controls cannot be set on pipe, direct connection or arena models and are not applied to automation runs. Commit, Commit, Commit, Commit, Commit, #31972
Compaction during long tool runs. With context compaction on and native function calling, a reply that runs many tool calls in a row is now compacted between tool rounds once its context passes the token threshold, keeping each tool call together with its results and giving the summary the tool names and arguments, where compaction only ran before the reply started and a long tool run could grow past the model's context. Commit, #27599
Multi-file skills with version history. Workspace skills can now hold supporting files such as scripts, references and templates next to SKILL.md, managed in a file tree in the skill editor, and every save keeps a version you can page through, compare with the current one, make the live version again or delete. Skills import from a ZIP folder, a JSON file or a single SKILL.md with a preview first, and export as ZIP or JSON. Models can read a skill's supporting files and create skills or edit their files on their own, so for anyone allowed to create workspace skills "/skills:create" now saves the new skill straight to the workspace without needing a terminal.

Knowledge bases as a file browser. A knowledge base now opens with its folders and files on the left and the selected file next to them, where you can switch between a preview of the original file and the text the model searches, edit that text in place or download the file, with search, filters and sorting above the list and a question before unsaved edits are dropped.

Redesigned model editor. The model editor has a new layout: the background image now fills a banner at the top with the model's picture, name and ID set over it and buttons to add, change or remove it on hover, a long system prompt opens folded to a short preview with Show more, and Capabilities, Default Features, Builtin Tools, Knowledge, Tools, Skills, Filters, Actions, Prompts, Voice and Terminal each fold into one row that summarizes what is set, such as "Web Search, Image Generation +2", "3 of 9 enabled" or "Custom 4", and opens into switches with descriptions or a searchable picker with Enable all, Clear and a Manage link. Advanced Params shows how many parameters are changed, every setting name explains itself in a tooltip, Save & Update with the change note stays at the bottom of the editor, default features now sit with Capabilities and only list the capabilities that are on, default filters are switched on per filter inside the Filters picker, Knowledge has its own picker with Upload Files, empty lists point to the workspace where items are added, and the admin Model Defaults panel uses the same rows.

Model version history. Every save of a workspace model now keeps a version you can page through in the model editor, make the live version again or delete, and a version whose knowledge, tools, functions or terminal are gone or no longer yours to use is refused instead of being switched on half working. Commit, Commit
Tool and function version history. Every save of a tool or function now keeps a version you can page through in its editor, make the live version again or delete, so a change can be tried and rolled back without creating a copy and setting it up again. #29496, Commit
Compare prompt versions. The prompt editor's history now compares any earlier version with the current one in a diff view and can start editing from an old version as a new one, and asks before unsaved changes are dropped. Commit, Commit
Tool Search for large tool sets. Administrators can now turn on Tool Search, marked experimental, in Admin Settings > Interface, so tools with long definitions are left out of the request and only listed by name and a short description, and the model looks up the full definition with a search_tools tool when it needs one, which keeps the prompt small and the prompt cache intact when many tools or MCP servers are enabled; the Deferral Threshold sets the definition length in characters above which a tool is held back, Always Loaded Tools takes names or patterns such as github\_\* that are always sent, and Defer Built-in Tools decides whether built-in tools are held back too. It applies with native function calling and can be set with "ENABLE_TOOL_SEARCH", "TOOL_SEARCH_DEFER_THRESHOLD", "TOOL_SEARCH_ALWAYS_LOADED" and "TOOL_SEARCH_DEFER_BUILTIN_TOOLS". Commit
Nested groups. Administrators can now give a group a parent group, so members of the inner group also get everything shared with the parent groups above it and their permissions, the group editor shows the inherited permissions and lists direct and inherited members separately, deleting a group moves its subgroups up to its parent, and open browsers pick up changed group access right away without reloading. Commit
Default models per group. Administrators can now set default models for a group in its settings, which its members get for new chats instead of the global default, with the most deeply nested group winning when several apply and a user's own default models still taking priority. Commit
Fork shared chats. Shared chat links and chats you can only read, such as ones in a folder shared with you, now have a fork action on each finished reply, which makes your own copy of the conversation up to that message; a fork from a share link holds only what was shared, and a fork of someone else's chat leaves out their folder, pin and chat variables.

Import skills from a URL. Administrators can now pick Import from URL in the Skills workspace import menu to load skills from a GitHub repository, a GitHub folder or SKILL.md link, or a direct link to a ZIP, JSON or Markdown skill file, which open in the import preview to pick from; downloads are checked against internal addresses on every redirect and capped at 200 MiB.

Skills on the community site. With Community Sharing on, the Skills workspace now has a Discover a skill link to the skills on openwebui.com, the skill menu has Share for people allowed to export skills, which sends the skill with all its files to openwebui.com, and a skill opened from openwebui.com loads straight into the new skill editor for people allowed to import skills.
