Meta's engineering team has developed an AI agent that functions as a 'second brain' for organizations, integrating a structured, auditable knowledge architecture to preserve and share expert knowledge. The agent is designed to act as a secondary expert in a domain, making deep specialist knowledge accessible to all employees. The system's novelty lies in its two-layer integration, which separates knowledge for auditability and learning.
