Microsoft Copilot: GPT 6.1 Sol and Claude Sonnet 5.5 beginning to roll out today

🚨 The Signal: New large language models, GPT-6.1 Sol and Claude Sonnet 5.5, are rolling out to Microsoft Copilot, Copilot Studio, and M365 apps. This expands AI capabilities but requires explicit subprocessor enablement for data handling.

The Impact

Admins and Security Teams are affected by the need to review and enable new subprocessors, introducing potential data handling and compliance risks.

• Security Teams: Must assess data handling implications of new AI subprocessors.
• Admins: Need to enable OpenAI and Anthropic subprocessors for model access.
• Compliance Teams: Review data residency and privacy policies for new AI models.
• End Users: Gain access to new AI models, increasing potential for data exposure if not governed.

The Action

1. Review your organization's data residency and privacy policies concerning OpenAI and Anthropic subprocessors.
2. Assess the data classification and sensitivity of information processed by Copilot and Copilot Studio.
3. Enable the OpenAI subprocessor in Microsoft 365 admin center if GPT-6.1 Sol is desired.
4. Enable the Anthropic subprocessor in Microsoft 365 admin center if Claude Sonnet 5.5 is desired.
5. Communicate acceptable use policies for Copilot with new AI models to end-users.
