HASI

Also: Human-AI Synergy Index · HASI — Human-AI Synergy Index (Measurement Formula) · HASI — Human-AI Synergy Index

A measurement framework treating intelligence as structured orchestration. Defines Transformation Efficiency (η) as the core metric for how effectively a human-AI system converts raw information into actionable output. Designed to help learners and operators optimize personal Information Architecture rather than raw compute investment. Distinct from the η Transform (mathematical) — HASI is the applied measurement system for human performance optimization.
