Microsoft 365 Copilot integrates Anthropic AI models
Microsoft has integrated Anthropic AI models into its online services, including Microsoft 365 Copilot, offering expanded AI capabilities under Microsoft's security framework and customer commitments.

What happened?
Microsoft has introduced an integration of Anthropic AI models into its online services. This integration means that Anthropic acts as a subprocessor to Microsoft. The change aims to simplify the user experience and strengthen compliance and security within Microsoft's enterprise-grade framework.
Key facts
”Microsoft is introducing a new offering with Anthropic AI models as part of Microsoft Online Services, delivering enterprise-grade commitments and safeguards to ensure secure and responsible use of Anthropic models within your organization.”
”As a subprocessor, Anthropic operates with Microsoft oversight through contractual safeguards and appropriate technical and organizational measures.”
”Microsoft enables Anthropic models on by default for most customers in commercial cloud (excluding EU/EFTA and UK).”
Why it matters
The integration enables the use of Anthropic's advanced AI models within the Microsoft ecosystem, while maintaining corporate promises regarding security and compliance. This includes the Microsoft Customer Copyright Commitment (CCC) for products such as Microsoft 365 Copilot and Copilot Studio, providing companies with security regarding copyright liability.
Who is affected?
Companies and organisations using Microsoft 365 Copilot and Copilot Studio are affected. Specifically, it concerns customers who want to leverage Anthropic's AI models within Microsoft's secure and regulated environment. Microsoft's Enterprise Data Protection applies to the use of these models.
Impact on the EU
Anthropic models are enabled by default for most commercial cloud customers, except for those in the EU/EFTA and the UK. For these regions, a separate activation process or specific considerations are likely required due to data protection regulations.
What else you should know
Microsoft's Product Terms and Data Protection Addendum (DPA) apply to the use of Anthropic models via Microsoft's enterprise services, except for models marked "Preview models with Data Retention". This ensures the protection of customer data.
