Meta Unveils 'Second Brain', an AI for Organizations to Learn Expert Knowledge

Meta has developed Second Brain, an AI agent that systematizes and preserves expert knowledge within organizations to make it easily accessible. The system applies an auditable, structured knowledge architecture by separating knowledge from the reasoning process.

The core feature is a self-improvement loop that reflects expert feedback without retraining the model. This maintains consistent, high-quality output even in large-scale evaluations, allowing experts to focus on complex tasks and improving productivity.
