Meta Engineering Unveils Organizational Second Brain System

Meta's engineering team published details on its "Organizational Second Brain," an internal AI architecture that continuously absorbs institutional knowledge from pull request reviews, design RFCs, and incident post-mortems. By pairing continuous low-rank adaptation (LoRA) distillation with a dynamic kernel scheduler, the system prevents catastrophic forgetting while updating its internal model weights daily. The approach overcomes traditional enterprise knowledge fragmentation across disparate documentation systems.
