Agent Memory Is Not Just Better RAG: What Grep and AKBP Are Really Saying

An arXiv paper found that inline grep often beats vector retrieval on long-memory conversational QA, while AKBP turns agent memory into a local-first, review-gated, file-backed protocol. Together, they point to the same lesson: agent memory is not a search feature. It is systems engineering.

Dr. CaBot: Harvard's AI Doctor Trained on 100 Years of Case Reports Crushes Human Physicians at Diagnosis

Harvard's Dr. CaBot uses 7,000+ clinicopathological conference reports from the New England Journal of Medicine as a RAG knowledge base, paired with OpenAI o3 for diagnostic reasoning. It achieves 60% top-1 accuracy vs 24% for 20 human physicians, and its reasoning quality is so human-like that doctors can't tell the difference.
