We’re building Copilot as a new OS for work that spans every model, every form factor, and every task. Today, we’re announcing our biggest update to Copilot to date, bringing four things together: · Autopilot: proactive and long-running agent built for the enterprise · Code: build apps with Copilot, hosted inside your company’s tenant · Home: Chat + Cowork together · Office: now fully embedded in Copilot (and Copilot embedded in Office, of course!) Plus, you can invoke Copilot in Teams, and we’re introducing Today, a proactive experience that surfaces the most important information from across M365 without needing to ask for it. The way we work is changing and so are our workflows. This update brings AI into that flow, from answering a question, to building an app, to getting work done on your behalf.

We’re bringing the full power of Microsoft Office into the Copilot app, so you can go from initial idea to finished work all in one place, with the fidelity, performance, and collaboration you rely on. Looking forward to you giving it a try in Frontier soon. Learn more: aka.ms/AA13g7uq

Incredible job PowerPoint team. GPT-Image-2.5 brings more precision and control to image creation in PowerPoint. Looking forward to seeing all the new images people create in @powerpoint presentations.

Two new frontier models are available as part of the model choice with @MSFTCopilot : Claude Opus 5.5 and GPT-6 Sol. Looking forward to seeing what this unlocks for customers in their Excel, PowerPoint, and Word documents. techcommunity.microsoft.com/…

In @Microsoft365 , the handoff stops short of the decision. Word shows you the exact words Copilot changed, highlighted in place so you can accept or reject them, and all of it runs against your own files, inside the permissions you already had. Trust matters when you are delegating work, whether it is to a colleague, model or tool. Keeping that ownership in the hands of the user is at the core of what we build.

Any pursuit of superintelligence has to be grounded in the core principle that if the AI we build is not helping humanity and under human control, it's not worth pursuing. We also need to accelerate and spread the benefits of AI, such that they are diffused broadly across countries, communities, and companies. This requires a frontier ecosystem in which both closed and open-source models can thrive. And for firms, it’s imperative that they retain full control over their unique and tacit knowledge. Every organization should be able to build its own continuous learning loop/hill climbing machine, without becoming dependent on any one model provider, and have the ability to embed its own knowledge into models and weights they control. So, in this context, we welcome the research, focus, and deliberate pacing needed to get alignment right as the design goal. We also welcome ideas like "embedded evaluators" and the broader efforts to develop the mechanisms to make this more than just talk. The key is that this cannot be controlled by a handful of entities, but must have broad representation across the ecosystem, countries, and fields, including academia. This is the approach we are taking: broad access and choice at every layer of the AI stack; enterprise control of learning loops and models; and the “Code of Conduct” that underlies our own first party MAI models that we’ll publish tomorrow for public consultation.

Welcome @grok to Microsoft Copilot inside of Word, Excel and PowerPoint.

More model choice coming to Copilot. Welcome Grok!

Where does football meet @msexcel ? Brian Eayrs runs analytics for the @Seahawks, and one of his favorite Copilot prompts is to have it teach something back to him the way a football coach would. Worth the watch. microsoft.com/en-us/ai/see-y…

Starting today, GPT‑5.6 is beginning to roll out across Word, Excel, and PowerPoint. Whether you're drafting a document in Word, analyzing data in Excel, or building presentations in PowerPoint, GTP - 5.6 brings stronger reasoning and higher-quality outputs right where work gets done.

Today we're making Copilot in Microsoft Excel even better for finance specialists by adding skills, financial data connectors, and improved control over outputs. These are real workflows used every day across the industry. Learn more at lnkd.in/gDzXXScN

So much of @satyanadella article resonates with what I am hearing daily from Enterprise leaders. If you have not done so already, please take the time to read it in full: “Our priority has to be building a frontier ecosystem, not just a frontier model, so value flows broadly across every company, every industry, and every country. One where every organization can own the learning loop that encodes its institutional knowledge, compounding its human and token capital.” - Satya

I’m biased but agree :)

The suite of MAI models will start rolling out to Word, Excel, PowerPoint & Outlook soon alongside the other foundation models. Giving customers more choices between capabilities, performance and efficiency for the job that need to be done. (@mustafasuleyman - Great job MAI team) microsoft.ai/news/building-a…

Copilot in Excel can pull trusted data from LSEG and Moody’s—including market data, credit ratings, and research—directly into your workbooks. This is the first set of trusted data providers we’re bringing into Excel via MCP, with more coming soon. Learn more: techcommunity.microsoft.com/…
