What Happened? The Rumors and Reality Behind GPT-5.6 and Copilot
If your business depends on Microsoft 365 Copilot to draft emails, analyse spreadsheets, or create presentations, you probably felt a jolt last week. News broke that Microsoft was quietly swapping out OpenAI’s models for its own in-house AI in Word and Excel — and for a moment, it felt like the ground was shifting under a tool many Malaysian SMEs now rely on daily.
TL;DR: OpenAI just announced that its latest model, GPT-5.6, will be the “preferred model” for Microsoft 365 Copilot, pushing back against talk of a split. But Microsoft is still building its own MAI models to keep options open. For SME owners, this means Copilot will keep working as expected, but you’ll want to stay aware of how the AI landscape behind your favourite tools is evolving.
What “Preferred Model” Actually Means — and What It Doesn’t
When OpenAI launched GPT-5.6, it stated that the model would become the “preferred model” powering Copilot across Word, Excel, PowerPoint, and the Cowork app. The phrasing is deliberately vague. As the original report noted, “what being a ‘preferred model’ actually means isn’t entirely clear, other than that OpenAI’s software will continue to power Microsoft’s apps.” (TechCrunch)
So no, Copilot isn’t going anywhere. But the word “preferred” — rather than “exclusive” — leaves the door open for Microsoft to lean more on its own MAI models behind the scenes, especially for tasks where internal models are cheaper or faster.
“Our partnership with Microsoft has always been about bringing the benefits of advanced AI to more individuals and organizations, and we’re excited to continue building on that shared commitment.” — OpenAI
This doesn’t change the fact that Microsoft may still be reducing its reliance on OpenAI over time. But for now, the partnership is alive, and GPT-5.6 is the engine your Copilot will use.
Why Malaysian SMEs Should Pay Attention
If your business is like many SMEs in Malaysia, you’re probably already using Microsoft 365 — and maybe Copilot — to speed up routine work. That’s exactly the kind of integration that makes this news relevant.
- You’re tied to the platform: Copilot is seamlessly embedded in the apps your team uses every day. Any change in the underlying model could affect speed, accuracy, or features.
- You benefit from competition: Microsoft developing its own models (the MAI series) could eventually mean more tailored AI features for business users, but it also introduces uncertainty about which “engine” is driving your work.
- Stability matters: OpenAI’s reassurance means you can keep using Copilot without immediate disruption, but the fact that Microsoft is building alternatives suggests you should plan for potential shifts down the road.
For now, the message is: don’t panic. But do stay curious.
The Bigger Picture: AI Partnerships Are Evolving
What’s happening between OpenAI and Microsoft is a pattern we’re likely to see more of across the tech world. Partnerships that once looked like exclusive alliances are becoming more fluid. Both sides want to retain flexibility — Microsoft to control costs and direction, OpenAI to maintain independence and clout.
For SME owners, the takeaway is clear: building your workflows around a single AI provider carries hidden risk. Tools you depend on today may look very different two years from now — not because they’ll disappear, but because the underlying technology might shift.
The smarter approach is to stay platform-aware without becoming platform-locked. Use integrations that are modular where possible, and keep an eye on announcements like this one. They signal which way the wind is blowing.
Old Assumption vs. New Reality: What’s Changing?
| Aspect | Old Assumption | New Reality |
|---|---|---|
| AI model source for Copilot | Almost exclusive use of OpenAI models | OpenAI’s GPT-5.6 is “preferred,” but Microsoft’s MAI models are also used selectively |
| Microsoft’s dependency on OpenAI | Fully reliant on OpenAI for Copilot features | Actively building in-house alternatives to reduce reliance |
| Impact on your daily use | Same model all the time | Possible variations in behavior across tasks |
What You Should Do Now
Instead of worrying about which company “wins,” focus on how you use AI in your daily operations. Test how Copilot performs with GPT-5.6 when it rolls out. Compare it with standalone AI tools you might use for content or data analysis. If your business relies heavily on specific Copilot features, now is a good time to map out what would happen if those features changed.
And if you’re already thinking about integrating AI more deeply — or automating other parts of your operations — it might help to get a second opinion from someone who follows these shifts full-time.
