The Unreasonable Effectiveness of Taught Machines

AN ENGINEERING ZINE — DRAWN & BUILT BY HAND NOW — AI ENGINEERING @ GOLDMAN SACHS "we shape our tools; thereafter
they shape us."

Form Derivation

six systems, one obsession — teaching machines to be useful ↓

(1) DOCUMENT INTELLIGENCEGoldman Sachs · serverless extraction end-to-end · −50% manual work

(2) KNOWLEDGE-GRAPH RETRIEVALGoldman Sachs · graph-native answers, beyond RAG · in production

(3) AI FOR CLIENTSGoldman Private Wealth · advisor & client intelligence · details stay at the desk

(4) COMPUTER-USE AGENTBNY · Claude on-prem, language → action · secure by design

(5) EARLY CANCER DETECTIONwith Chennai Cancer Institute · vision transformers · the one that matters

(6) CYCLONE INTENSITYNASA · CNNs over INSAT-3DR imagery · 96% accurate

agents models knowledge governance

EXPLODED VIEW — WHAT HOLDS IT UP

Every serious AI system is these four floors. Agents act, models think, knowledge remembers — and in finance, governance is the floor that keeps the whole building standing.
