Microsoft CEO Satya Nadella announced Project Opal for Microsoft 365 Copilot on September 7, enabling AI agents to execute complex, long-term tasks autonomously. The feature operates within a controlled environment, allowing AI to work for hours or days on tasks like analyzing footage and generating reports. It uses a reasoning model to convert natural language into dynamic plans, adjusting tool calls as needed. Early applications include compliance audits, where engineers save up to 20 hours weekly by automating data collection and verification. Users access Project Opal via the Frontier module in Microsoft 365 Copilot desktop or web versions.
