Microsoft Copilot will soon support Grok models from xAI. Word, Excel, and PowerPoint users in the Microsoft Frontier Program can test Grok models now, with general support expected to roll out in the future.
Grok models are being added to Microsoft's Online Services Subprocessor list. By offering different models as subprocessors, Microsoft can give customers access to those models without people having to switch away from the overall Copilot experience.
For example, Researcher Agent in Microsoft Copilot works with Claude AI models from Anthropic. Other Copilot experiences may use multiple AI models to complete tasks.
"Our multi-model strategy gives customers access to leading AI models while maintaining the trusted Copilot experience," said Microsoft in a Tech Community post.
For different models to appear as options, admins need to enable them through the settings of their respective organization.
During the testing period, Grok models will not be available in the European Union, European Free Trade Association, or the United Kingdom.
Subprocessors are third-party providers that help Microsoft deliver online services. Microsoft has an expansive list of subprocessors used for everything from powering data centers to completing tasks in Copilot.
Using Grok as a subprocessor helps Copilot tackle different tasks and provides redundancy that protects against outages or issues with other subprocessors. But users should not expect the witty or irreverent tone and style that Grok has become known for on X.
Subprocessors sit under Microsoft's system prompts and enterprise guardrails, so the generated responses will still be professional. Essentially, you get the benefit of Grok's multi-step logic and mathematical prowess but within Copilot.
Once an admin enables the integration, you can set Copilot in apps like Word, Excel, and PowerPoint to automatically pick the best model for a task, or manually pick between GPT, Claude, or Grok directly from a drop-down menu in the interface.

Google Gemini now competes with Microsoft Copilot for space on your keyboard. Google just released Gemini for Windows, and that app uses the same keyboard shortcut as Copilot (Alt + Space).
That shortcut is popular and those hoping to use Gemini may have to remap some shortcuts to perform other tasks. In addition to summoning Copilot, Alt + Space opens PowerToys Run.
The Gemini app is available for both Windows 11 and Windows 10. You can download it through Google's website.
The general functionality of the Gemini app is similar to Gemini's web experience. One key difference is that you can summon the AI tool with a keyboard shortcut, which allows you to launch it quickly.
The macOS version of Gemini supports sharing your screen and other native capabilities, such as dictating by pressing both Command keys. Google explains that more native features will ship to the Windows version of Gemini in the future.
I prefer Gemini over Copilot for many tasks. I recently swapped to Google's AI tool for a month to see how it performed as an editor. While Copilot felt more personal, Gemini was often more accurate when it came to correcting tasks.
"In my specific use case, Gemini felt like an upgraded Microsoft Editor while Copilot felt like a modern Clippy," I said a couple months ago.
Both Copilot and Gemini have their strengths and weaknesses, but Google's option is better for my workflow. Our readers disagreed.
21% of those who voted in our poll about proofreading with AI use Microsoft Editor. Another 29% of participants use Microsoft Copilot. Only 11% of voters rely on Gemini to proofread documents.
Of course, Gemini and Copilot can do a lot more than proofread documents. Google recommends the new Gemini app for fact-checking documents, coming up with titles for a presentation, and creating images and videos.
For more complex tasks, you can hand things off to Gemini Spark within the app.

It’s not every day that attackers can force a frontier AI model to cough up user passwords and other sensitive data without user confirmation. That’s exactly what researchers recently did to Microsoft 365 Copilot for enterprise. Even more unusual is the source they tapped to discover the critical vulnerability that made their exploit possible. Rather than employing reverse engineering or other traditional vulnerability-hunting methods, they asked Copilot. The LLM assistant readily complied.
Researchers at security firm Varonis knew they wanted to create an exploit that would exfiltrate user data when a user did nothing more than click on a link. Like most AI assistants today, Copilot steadfastly refused and made clear that sensitive prompts like that require explicit user consent in the form of a gesture, such as pressing a return key or other key. In response, the researchers peppered Copilot with questions about the guardrails that required user confirmation before the assistant could execute powerful commands.
The dialog was like a game of 20 questions. Each answer provided a new clue that divulged information about the complex safety mechanism. Why was auto-execution impossible, they asked. What URL structures and deep links were involved? What happens when a page is loaded with input already in the prompt field? Each answer provided a deeper view into the guardrail and its limits. Eventually, Copilot provided a stunning Microsoft trade secret—an undocumented prompt parameter that completely bypassed the requirement for user consent.

It's the year of Linux, haven't you heard? You may as well pack up your PC, study your favorite distro, and get ready to evangelize the open-source platform that will run on all systems in the future.
Joking aside, Linux has grown a bit in popularity and Microsoft continues to embrace it. While the tech giant has several apps and projects on Linux, Microsoft has not released an official Copilot app for Linux.
Sure, you could use Copilot on the web. Heck, you could even open up Microsoft Edge for Linux and install Copilot as a PWA (Progressive Web App). But where is the fun in that?
Instead, you could install the unofficial Copilot app for Linux built by Hayden Barnes. The app opens the Copilot web app in a dedicated GTK window and keeps your login session safely on disk. It also integrates with the desktop for autostart, system downloads, app launcher execution, and accessing hardware permissions like the microphone.
Barnes shared the project on X alongside a link to the app's GitHub page.

Many of the unofficial Copilot app's features overlap with using the web version of Copilot since Microsoft's AI tool is the center of the experience. But building the unofficial app as a native GTK application means its developer can deeply integrate system shortcuts, allow it to run quietly in the system tray, and trigger native OS notifications as opposed to relying on browser notifications.
Other benefits include native support for desktop accent colors and system dark themes. Overall, the app looks and feels far more natural on a Linux desktop than a standard browser window, and keeping Copilot isolated prevents it from slowing down if your main browser gets bogged down with dozens of open tabs.
The unofficial Copilot app for Linux is new, so we'll have to use it for a while to determine its long-term stability and performance. The first publicly available release of the app shipped this week.
We have a few systems running Linux spread across our team, so we'll let you know how the unofficial Copilot app performs over time.

A Adobe anunciou hoje o lançamento de um plugin unificado para o ChatGPT, reunindo mais de 70 ferramentas criativas da seu suíte diretamente na interface do chatbot por inteligência artificial (IA) da OpenAI.
O plugin conta com ferramentas de aplicativos da Adobe que já possuíam integração com o ChatGPT, além de novos recursos do Adobe Express, Photoshop, Firefly, Premiere, Acrobat, Lightroom, Illustrator, InDesign e Adobe Stock, permitindo que os usuários possam criar peças publicitárias ou adaptar um vídeo para diferentes redes sociais sem precisar alternar entre aplicativos.
A novidade faz parte da estratégia da Adobe de expandir a compatibilidade dos seus recursos com as ferramentas de IA generativa; em junho, a empresa já havia mencionado que levaria esses recursos inclusive para rivais do ChatGPT, como o Claude. No Copilot, no Gemini e no Slack eles chegarão “em breve”, segundo a empresa.
Big news: a new Adobe plugin is now available in @OpenAI's @ChatGPT! 70+ tools, including @Photoshop, @AdobeFirefly, @Lightroom, and @Acrobat, all in one chat.

Ainda conforme a desenvolvedora, a novidade foi pensada para “facilitar e agilizar a transformação de ideias em conteúdo de alta qualidade dentro do ChatGPT”, mas a empresa destaca que, para necessidades criativas “mais profundas”, os seus aplicativos nativos seguem sendo a primeira opção.
Questionada pela AI Magazine se o uso dos recursos incorporados ao ChatGPT poderia rivalizar com o uso dos aplicativos nativos, a líder de produtos de IA agêntica da Adobe, Deepti Pradeep, respondeu o seguinte:
Dentro do ChatGPT, a experiência é transformadora: em vez de escolher plugins da Adobe separadamente, os usuários podem experimentar uma única experiência da Adobe que traz o Photoshop, Acrobat, Express e mais juntos.
Nós acreditamos que a consolidação adiciona mais valor aos usuários do ChatGPT. Fora dele, nossos aplicativos nativos permanecem essenciais para um controle mais profundo, preciso e avançado dos fluxos de trabalho.
Para iniciar, é possível utilizar algumas funcionalidades do plugin como convidado, embora a Adobe recomende fazer login com a sua conta para “desbloquear recursos adicionais”.
O plugin da Adobe já está disponível tanto no app quanto na versão web do ChatGPT.

Last Tuesday, Microsoft patched a vulnerability it rated as max critical in its M365 Copilot AI platform. On Monday, the researchers who discovered the vulnerability and reported it to Microsoft revealed how their proof-of-concept exploit could retrieve 2FA codes and other sensitive data from emails accessible to Copilot.
Microsoft and other LLM providers have been unable to prevent their products from complying with malicious requests to reveal data. The root cause: AI bots are unable to distinguish between instructions provided by users and those snuck into third-party content the models are summarizing, drafting responses to, or using to perform other actions on behalf of the user. With no way to secure this crucial boundary, Microsoft and its peers are left to erect complicated and ad hoc guardrails designed to rein in the consequences of this incurable gullibility.
One guardrail built into Copilot and most other LLMs prevents them from submitting web forms, sending emails, and taking similar actions that can be used to exfiltrate data from the user. To work around this, LLM hackers turned to markup language, which, among other things, allows users to add formatting elements such as headings, lists, and links to text without the need for HTML tags. Another workaround is to wrap sensitive data inside HTML tags such as <img> and <form>. In either case, a web request showing the data hits the attacker’s web server, where the secret information is captured in logs.

Microsoft's Build developer conference kicked off today, and as with almost everything the company has done in the last few years, Microsoft's opening keynote focused overwhelmingly on AI and other closely related technologies. There's Microsoft Scout, an OpenClaw-based "Autopilot" agent that can hook into Microsoft 365 data to perform tasks for users; several new AI models; an expanded preview of "Codename MDASH," which is a "multi-model agentic scanning system" meant to detect and fix software vulnerabilities.
A few of those announcements stood out to us as particularly interesting, either for esoteric technical reasons or because they seem like they may have some utility for those who aren't spending their every waking moment using generative AI tools. (Microsoft's recent efforts to make its flagship operating system faster, more reliable, more useful, and less annoying didn't really come up, but there have been plenty of other announcements on that front lately.)
On the hardware front, we didn't get any updates for existing Surface devices (not counting yesterday's Surface Laptop Ultra announcement), but we did get something new: the Surface RTX Spark Dev Box is "a compact developer PC" built around Nvidia's new RTX Spark chip with up to 128GB of built-in memory.
