Four layers. Four domains secured. One overarching philosophy. This is the architecture for the category we are creating and the vocabulary that will define how the enterprise market talks about AI efficiency for the next decade.
The Problem
Maximum-by-Default is the enemy
The prevailing assumption is to deploy the most powerful available model for every task. GPT-4 for intake forms. Frontier inference for structured extraction. This is not sophistication. It is waste built into the default architecture decision.
The Philosophy
Lean AI is the discipline that follows
Every transformative technology follows the same arc. Expensive and unoptimized first, then efficient and commoditized. Cloud did it. AI is next. Lean AI is the name for the efficiency discipline that follows every technology hype cycle. It always comes.
The Opportunity
No analyst has named it. No vendor owns it.
Five terms are competing to describe the same imperative: Lean AI, Frugal AI, Efficient AI, Economic AI, Sustainable AI. No analyst has named it. No vendor owns it. The practitioner who publishes the first credible, dated, cited definition owns the reference point permanently.
