In this episode of the YPO Technology Network AI Brief, Stephen Forte examines Microsoft's multi-model Copilot rollout — one of the most substantive architectural changes in enterprise AI this year. The episode covers what's deploying now, what goes generally available May 1, and why the gap between Microsoft's installed base and active usage is a change management problem, not a technology problem.

Key topics covered:

• Multi-model Copilot: Critique and Council modes — GPT and Claude reviewing each other's work, producing a 13.8% improvement on the DRACO research benchmark; Council mode runs multiple models in parallel and synthesizes where they agree and diverge
• Copilot Cowork and Agent 365 — long-running agentic work that continues after you close the browser, currently in the Frontier program with Capital Group; Agent 365 goes GA May 1 at $15/user/month
• The adoption gap — Microsoft has 400 million installed users but only 15 million paid Copilot seats (3.3% penetration); of those, only 35.8% are actively using the product versus ChatGPT Enterprise's 83.1% activation rate
• Copilot Studio model marketplace — April GA brings a platform where enterprise developers can orchestrate Claude, GPT, and Grok models against internal data via Fabric integration and the Agent-to-Agent protocol

Pricing referenced:

• Agent 365: $15/user/month (GA May 1)
• Microsoft 365 E7 bundle (E5 + Copilot + Agent 365): $99/user/month (GA May 1)
• Copilot enterprise: $30/user/month; SMB: $21/user/month
