Abstract

Owned, self-hostable AI versus a metered cloud chat — on deployment and control, not benchmark scores. Includes a measured productivity case: on a regulated build where every engineer had the same frontier model (Claude), the client's own audit found one engineer on Hanzo's agentic stack shipped more than three contractor pods combined at ~250x-900x lower cost per line — the differentiator being the owned agentic stack, not the model. Covers data residency, air-gapped operation, provenance, post-quantum security, and cost at scale.
