Claude Fable 5.2 rolls out in Copilot Cowork and Copilot Studio

Microsoft started rolling out Anthropic's Claude Fable 5.2 in Copilot Cowork and Copilot Studio.

In Copilot, Work IQ grounds the model in your organization's files, meetings, chats and business data within existing permissions, so responses draw on your actual work and not only the prompt. Microsoft says the model brings stronger reasoning and coding to complex tasks.

The rollout is going to eligible users. Admins can manage access and set availability in the Microsoft 365 admin center, and Microsoft says availability may vary by region and organization.
