Anthropic Claude Fable 5.1 model now available in Microsoft Copilot



 Microsoft 365 Copilot Blog:

Claude Fable 5.1 is now joining the frontier models available in Copilot Cowork and Copilot Studio, giving customers more choice as they delegate more complex tasks to AI.

Fable 5.1 is designed for long-running work, financial analysis, and front-end visual coding, with tighter plans up front and more concise summaries at the end.

As more work is delegated to AI, the quality of the result depends on both the model and the context. Work IQ grounds Fable 5.1 in your files, meetings, chats, and business data—within your existing permissions—so it can reason over your work instead of the prompt alone resulting in more relevant and accurate responses, with sources you can trace back to your work.

Get started today​

Claude Fable 5.1 is rolling out today to eligible users in Copilot Cowork and Copilot Studio.

Availability may vary by region and organization. Admins can manage access and configure availability for their organization through the Microsoft 365 admin center.

For the latest rollout information, see Microsoft 365 Roadmap and Microsoft Copilot release notes.

To learn more about the model, see Anthropic’s announcement of Claude Fable 5.1

Wish MS would drop their habit of having confusing names for different software products. Copilot has suffered the same fate as Office 365 and Microsoft 365.

With Copilot I've got 3 different types on this computer.
1. Copilot (the version in Windows).
2. Microsoft 365 Copilot (comes with my Microsoft 365 Business subscription).
3. Copilot - Windows Performance Analyzer (WPA) AI (this isn't a chatty AI, quite the opposite and is a very serious diagnostic AI node capable of deep analysis of Windows related issues via ETL traces). Simply the best Windows diagnostic tool I've used.

    Still assembled, still runs. Haven't turned it on for 15 years?
Yeah, they have really bungled the names over the years.

We used to have Copilot Pro years ago, which is now apparently called Microsoft 365 Premium. Seriously, that's a terrible name for it. You can buy Microsoft 365 Premium and 6 people can use it, but only the account owner gets any copilot features whatsoever.

But if you work organization has an MS365 subscription, it's called M365 Copilot. I just happen to have the Premium version, so it lists it as M365 Copilot (Premium) and it has a WORK tag on it.
