v26.11.1, build 260 (2026-11-xx xx:xx UTC)

• Added a setting for the size of the interface, which you find in the app settings. You can choose a size for each of your screens, and AI Studio switches to it when you move its window to another screen. Thanks, Paul Koudelka (PaulKoudelka), for this contribution.
• Added formulas in code blocks to the chat: when an AI model puts a single formula into a code block marked as LaTeX, the chat now shows the formula instead of its code. A code block with a LaTeX document or with text in it stays code.
• Added buttons to copy and save the formulas in the chat. When you point at a formula, you can copy its LaTeX code or save it as a LaTeX file, and the export menu of an answer offers its formulas as well.
• Added support for OneNote sections (.one): you can attach them to chats and assistants and use them in your local data sources. AI Studio reads every page, including the text OneNote recognized in pictures and handwriting.
• Added the Mathematics tools as a prototype: the AI can now calculate exactly and work with formulas, right on your computer. It keeps fractions exact, gives results with up to 100 digits, solves equations, differentiates and integrates, and can check whether an integral really has the value someone claims. AI Studio checks the results numerically wherever possible, and the AI tells you when a result is only approximate. To try it, open the app settings, allow preview features down to prototype, enable Mathematics, and then choose Mathematics among the tools of a chat.
• Added a way for IT departments to preselect the options of the Prompt Optimizer, such as the prompt guide of your organization, the language of the optimized prompt, and the provider. They can lock each option or let you change it.
• Added your own prompt guide to the options of the Prompt Optimizer. Choose the file once, and the assistant uses it whenever you open it or start over, always with the current content of the file.
• Added a way to see the complete system prompt of a chat: the button with the eye in the chat toolbar shows the instructions the AI receives ahead of your conversation, part by part, such as your chat template, your profile, data from your data sources, and the instructions of your tools. You can copy each part or the complete prompt. Thanks, Jens Erler (j-erler), for this contribution.
• Improved the documentation for IT departments, which now lives in our wiki. It is sorted by task, explains the setup on Windows, Linux, and macOS, and offers complete configurations for typical needs, such as using only local models. The link in the app settings leads there, and the wiki also holds the installation guide in English and German.
• Improved the German translation throughout: we proofread all texts and corrected wrong labels as well as spelling and grammar mistakes. The texts now always address you formally and use the same terms everywhere.
• Improved the security of the connection between the app window and AI Studio.
• Improved how reliably AI Studio reads and stores your settings, chats, and backups.
• Improved how reliably AI Studio exchanges data with AI providers, external data sources, and web search services.
• Improved how reliably the Visual Briefing assistant stores your briefings, and how reliably the assistants of AI Studio read the answers of AI models.
• Improved how AI Studio colors code blocks: it now highlights them itself instead of through an extra script, which makes the app smaller. This works for Python, JavaScript, TypeScript, Java, C, C++, C#, Go, Kotlin, Rust, SQL, shell scripts, PowerShell, Lua, CSS, HTML, XML, JSON, and YAML; code in other languages, such as Ruby or PHP, appears without colors. When a code block names no language, AI Studio recognizes it from the code, colors the block, and suggests the matching file extension when you save it.
• Improved how carefully AI Studio reads the answers of AI models and external data sources: an answer that contains the same entry twice, possibly with two different values, is now refused instead of AI Studio picking one of them. This covers tool calls, the Assistant Builder, the Visual Briefing assistant, and ERI servers.
• Improved the order of the models when you add or edit a provider: AI Studio now sorts the numbers in model names by their value, so that, for example, a model with version 4.10 comes before one with version 4.9, and the newest models stay at the top of the list.
• Improved the information page, which now shows the Rust compiler that actually built your copy of AI Studio. Before, it always showed the compiler of our official builds, even for builds such as the Flatpak, which bring their own one.
• Improved the options of the Slide Assistant: a button in the field of the PowerPoint template removes your template again, so the assistant plans an outline only.
• Changed the size of AI Studio on laptop screens: it now appears in the same size on every laptop, whatever the scaling of your operating system. If you prefer the previous size, choose "System scaling" for the interface size in the app settings. Contributed by Paul Koudelka.
• Changed your local data sources and mailboxes to return at most as many matches as you set in their options. Before, they could return up to twice as many. Now the best matches of the search by meaning and of the search by words take turns, and when one of them finds only a few, the other one fills in.
• Changed the connection to Hetzner's inference API to its new address. Hetzner turns off the old address on November 10, 2026, so older versions of AI Studio can no longer use Hetzner after that date.
• Fixed AI Studio becoming unusable when an update failed after its download. The app now restarts with the version you have installed, so you can simply try the update again.
• Fixed configuration plugins you installed yourself being able to change the tool settings of your organization, such as the minimum provider confidence of a tool. These settings now follow the same rules as all other settings, which also gives you back your own values once your organization removes its configuration.
• Fixed the log of AI Studio reporting that a configuration plugin you installed yourself tried to take over a setting of your organization, even when the plugin does not contain that setting.
• Fixed the Agenda Planner assistant leaving out the location of your event when it suggests a social activity.
• Fixed the ERI Server assistant leaving out your description of the authentication process when it generates a server.
• Fixed the ERI Server assistant not writing some generated files to disk, such as docker-compose.yml. It now tells you about every file it could not write.
• Fixed configuration plugins being unable to lock the preselected provider, the preselected profile, or the transcription provider to none. An empty value now does this, as the example configuration plugin describes. Older versions of AI Studio ignore the empty value and leave the choice to your users.
• Fixed AI Studio loading none of your organization's configurations when one place, such as the Windows registry, named a configuration with an invalid ID. AI Studio now skips that entry and uses the configurations from the other places.
• Fixed chats being stored although you chose "Store chats manually" or "Disable workspaces". AI Studio now stores a chat only when you click "Save chat", or not at all while workspaces are disabled. In both modes, leaving a chat whose answer is still being written asks you first and stops that answer. Chats outside of workspaces that earlier versions stored this way appear among your disappearing chats once you use workspaces again.
• Fixed saving a code block as a file, where the last line could end differently from all other lines, for example, on Windows. All lines of the file now end the same way.
• Fixed the result of a tool in the chat showing umlauts, quotation marks, and other special characters as codes instead of the characters themselves.
• Fixed the Assistant Builder telling you in English why it could not use the answer of the AI model, even when you chose another language for AI Studio.
• Fixed requests to a provider failing when a configuration plugin gave it additional API parameters that contain the same parameter twice. AI Studio now sends the request without these parameters and names the repeated parameter in its log, as it does for other invalid parameters.
• Fixed the information page leaving out three libraries that AI Studio uses: MailKit and MimeKit, which read your mailboxes, and the Open XML SDK, with which the Slide Assistant reads and writes PowerPoint files.
• Fixed AI Studio asking you to install Pandoc when you load a file as the input of an assistant, although PDF, Word, Markdown, and most other files need no Pandoc.
• Fixed dropping a file onto your custom prompt guide in the Prompt Optimizer. Once you switch on "Use custom prompt guide", a marked area appears where you can drop your guide or select it with a button.
• Fixed Semantic Search leaving out passages of your data sources which did not fit into a single search. The AI now gets every passage it finds, page by page, and a passage too long for a whole page is shortened instead of left out.
• Fixed chats with data sources failing when you switched off Semantic Search, because AI Studio sent more passages along with your message than the AI model can read. AI Studio now sends only as many passages as fit, taking turns among your data sources, and tells you with each answer when some passages had to be left out.
• Fixed the AI search in your mailboxes leaving out mails which did not fit into a single search. The AI now gets every mail it finds, page by page.
• Fixed pages of AI Studio, such as those behind the icons of the navigation bar, opening in your web browser when you clicked them while holding Shift or Ctrl. Such clicks now do nothing, while links to websites still open in your browser, and now also from the AppImage on Linux. The right-click menu now appears only in text fields and on selected text, so it no longer offers entries such as opening a link in a new window.
• Upgraded several libraries to improve security.
• Upgraded Tauri to v2.12.5.
• Upgraded MudBlazor to v9.12.0.
• Upgraded to .NET v10.0.14.
