a Chinese model for Copilot Cowork?



Microsoft is considering putting a Chinese AI model inside its enterprise Copilot, and the reason is money.

The company told Axios it is exploring a self-hosted, fine-tuned version of DeepSeek V4, or another open-source model, as a cheaper option to power Copilot Cowork, the agentic assistant in its Microsoft 365 suite. It expects to offer a lower-cost model within weeks.

At the same time, Microsoft is moving Copilot Cowork to usage-based pricing, charging companies for the compute they actually burn rather than a flat fee.

Why even Microsoft can’t eat the bill

The shift is a window into the economics of agentic AI. Tools like Copilot Cowork, Anthropic’s Claude Code and OpenAI’s Codex call a model over and over as they work through a task, which is powerful and, it turns out, expensive.

“We have users who do hundreds of tasks a week, which is great, they’re way productive, but the consequence is the costs can go very high,” said Charles Lamanna, Microsoft’s executive vice-president for Copilot, agents and platform.

Copilot Cowork currently runs on Anthropic and OpenAI models, both of which have raised prices and pulled back from all-you-can-eat plans. Microsoft already metered GitHub Copilot for the same reason. A cheaper open-source engine underneath is the obvious next lever.

The cheapest option happens to be Chinese

That is where the calculation gets awkward. DeepSeek V4, released in April, is open-source, popular with developers and far cheaper to run, which is precisely why it is on Microsoft’s shortlist.

It is also Chinese, and the timing could hardly be worse politically. Washington has floated banning DeepSeek, threatened Chinese AI firms, and just forced Anthropic to cut off its top models for non-US users, a dispute that escalated into crisis talks with the Commerce Department.

Microsoft is clearly aware of how this looks. It says any DeepSeek option would be optional for customers and fully hosted on Azure, keeping data inside Microsoft’s cloud under its security, compliance and data-residency controls, and that it has fine-tuned the model and added safeguards, including changes meant to reduce bias.

A hedge against its own suppliers

The bigger picture is that Microsoft no longer wants to depend on any single lab. Freed from its tight, often tense exclusivity with OpenAI, it is pushing a multi-model approach, mixing and matching engines under its own roof.

For now this is an evaluation, not a decision, and Microsoft says it will confirm its choice when the cheaper tier ships. But that it is willing to even name DeepSeek as a candidate, in this climate, says a lot about how hard the cost of running agents has started to bite.

Microsoft has spent the last several years pushing Copilot and new user interface designs, which has meant that several great features included with Windows don’t get the recognition that they deserve. These are some of my favorites that will run on any Windows 11-compatible PC.

Clipboard history remembers everything you copy

Win+V replaces one of the oldest frustrations in computing

Windows’s default clipboard has been a source of minor but constant annoyance: it holds exactly one thing. If you copy something new, the previous item is wiped out. It is enough of a problem that multiple third-party apps were created to address the shortcoming.

Now, Windows has Clipboard History built in, though it isn’t enabled by default. To turn it on, press Windows+i, then navigate to System > Clipboard, and click the toggle next to Clipboard history.

Once it is enabled, you can press Win+V to view up to 25 items in your clipboard history, including text, images, and links.

If you have specific pieces of information you use daily—like an email signature, a common code snippet, or a home address—you should pin up some of those items. Pinned items persist between system reboots and clipboard history clears, which means you never have to hunt to find something when you need it.

You can even enable sync in the Clipboard settings, allowing your copied text to follow you between different PCs signed in to the same Microsoft account. Once you get into the habit of using Win+V, the standard copy-paste function will feel useless by comparison.

Voice typing actually works now

Win+H lets you write with your voice

Windows dictation software has a reputation for being clunky and difficult to use, but that isn’t the case anymore. Thanks to the improvements in AI that we’ve seen since 2024, voice typing accuracy has improved significantly, especially for technical vocabulary. You don’t have to spend your time manually fixing formatting either. The tool supports punctuation commands like “period,” “new line,” and “question mark,” which prevents your text from turning into a rambling mess.

To use voice typing, press Windows+H anywhere there is a text field.

While it isn’t a full replacement for high-end professional software, it is free, built-in, and more than good enough for long-form writing, taking down a sudden idea, or writing quick messages when your hands are full.

Snap layouts make window management effortless

Hover over the maximize button and pick a layout

You can manually drag windows to the edges of your screen to split your display up, but you’re doing more work than is necessary in most cases. Windows’ Snap Layouts allow you to instantly arrange your Windows into predefined halves, thirds, or quarters. Just hover over the maximize button on any window or press Win+Z.

One of the most practical aspects of this system is the Snap Group. If you snap a browser and a document side-by-side, Windows remembers them as a pair. When you Alt+Tab, you can bring the entire group back together.

Live captions transcribe any audio on your device

Real-time subtitles for anything you’re watching

You can enable real-time subtitles for any audio playing through your speakers by going to Settings > Accessibility > Captions, or by pressing Win+Ctrl+L. The audio is processed locally on your device; nothing is sent to the cloud, which is critical if you’re privacy conscious or if whatever you’re captioning demands confidentiality.

I’ve mostly taken to using it when it is too hot to wear my headphones. I can just toggle it on and keep watching without disrupting anyone around me.

There are some hardware requirements you need to meet. Basic same-language captioning works on any Windows 11 PC running 22H2 and up, but if you want real-time translation, you will need Copilot+ hardware with an NPU and at least Windows 11 24H2.

Dynamic Lock locks your PC when you walk away

Pair your phone via Bluetooth and your computer can lock itself automatically

I can’t count how many times I’ve stepped away from my PC only to think, “Dang, I forgot to lock my PC.”

Fortunately, Windows has an easy way to handle that automatically by pairing your phone with your PC. When your phone gets out of range (about 20 feet in my house, though your wall materials and layout will affect that), your computer will automatically lock after about 30 seconds. There is no need to install a separate app on your phone, the setup just uses the Bluetooth connection itself. While the 30-second delay means it isn’t a guarantee no one can access my PC, it does mean it won’t remain unlocked if I step away for a long time.

I especially like this feature when I’m working on my laptop in public.

You can enable Dynamic Lock by navigating to Settings > Bluetooth & devices and pairing your phone, then enabling Dynamic Lock in Settings > Accounts > Sign-in options.


Microsoft includes tons of great tools if you dig for them

These tools aren’t alone either. There are tons of practical tools buried in Windows, unappreciated and underutilized.

Each of these tools takes less than a minute to enable, but they can make a significant difference in your day-to-day workflow. It is worth the small investment of time to find them and set them up.

If you’re looking for even more advanced customization options, I’d recommend checking out Microsoft PowerToys. It gives you a huge range of fantastic tools that make Windows much more pleasant to use.
