Microsoft is expanding its Microsoft 365 Copilot platform with two new AI agents, Researcher and Analyst, set to roll out in April. Researcher combines OpenAI's research model with Microsoft's orchestration tools to perform complex analysis tasks, while Analyst leverages the o3-mini reasoning model for data analysis and visualization. The agents integrate internal work data with external sources, supporting third-party systems like Salesforce and ServiceNow. Available through Microsoft's "Frontier" program, these tools aim to deliver expert-level assistance for workplace tasks, featuring enterprise-level security controls and compliance measures.
