Microsoft has rebuilt Copilot into a single platform organized under three pillars: Home, Code, and Autopilot. Autopilot is the most significant functional change; agents can be given an identity, direction, memory, computer, and workspace, then operate continuously without further prompting. Scout, the first Autopilot agent, is powered by OpenClaw and integrates with Teams, Outlook, OneDrive, SharePoint, browsers, local resources, and MCP servers, appearing inside Teams like a colleague while handling background tasks such as invoice management. The persistent-agent design is enabled by models that can now run coherently for days and by memory that can live outside the model context. Microsoft already has over 30 million paid enterprise Copilot subscribers and is offering enterprise discounts of 30% to 50% to expand seat count, with plans to monetize later through usage revenue. Goldman Sachs projects monthly AI agent token use could reach 120 quadrillion by 2030, a 24x increase, with agents consuming 10x to 50x more tokens per request than chatbots due to planning, tool calls, and iteration; inference cost per token is expected to fall 60 to 70% per year as an offsetting factor. On the Sources Podcast, Nadella said the agent era will be 'even bigger than the cloud by orders of magnitude,' calling it 'probably the biggest TAM expansion ever.'
