At Build 2025, we introduced the Microsoft 365 Copilot APIs<\/a> to help developers bring grounded AI into their solutions without rebuilding indexes or compromising security. The response has been encouraging, and your feedback continues to guide the direction of the platform.\u00a0<\/span>\u00a0<\/span><\/p>\n

Customers are asking for deeper retrieval, better search, and simpler ways to generate answers that honor permissions and context. This Ignite 2025 roadmap update expands the Copilot API surface with new capabilities that make grounded AI more accessible, more reliable, and easier to integrate within the Microsoft 365 trust boundary.<\/span>\u00a0<\/span><\/p>\n

The Retrieval API is now generally available with improvements that strengthen grounding quality and broaden coverage across Microsoft 365 content. These changes reflect feedback from teams building RAG workflows and agents that depend on accurate, secure, and up-to-date context. The Retrieval API will also be available through Microsoft Foundry in preview, giving developers a new entry point for building enterprise grade RAG systems. <\/span>\u00a0<\/span><\/p>\n
