For the past several years, the dominant assumption in AI has been remarkably simple.<br>It has been a general consensus that the intelligence lives in large foundation models and everyone subscribes to their services or falls behind.<br>Users send prompts to increasingly sophisticated foundation models, receive answers, and pay for the privilege of doing so. Every interaction begins and ends with another inference request.<br>The business model is equally straightforward: intelligence is rented.<br>The more I think about where AI is heading, the less convinced I am that this architecture represents the end state of the foundation model industry.<br>In fact, it may instead eventually resemble the early mainframe era of computing instead.<br>The assumption embedded in most discussions about AI is that the valuable asset is the model itself. OpenAI, Anthropic, Google, xAI, and others are racing to build increasingly capable frontier systems under the assumption that this centralized model is the basis for their future.<br>That assumption deserves scrutiny.<br>The more interesting possibility is that foundation models eventually become teachers rather than workers.<br>The distinction matters.<br>Today, when a developer asks a frontier model to solve a problem, the interaction is largely ephemeral. A question is asked. An answer is returned. The transaction ends. Yes, the agents that sit on top of the LLM’s have evolved into magnificent beasts making a huge difference in outcomes and productivity but for now let's focus on the LLM’s themselves. Bear with me on this for now.<br>But the answer the LLM provides contains considerably more value than just the immediate response itself.<br>It contains reasoning patterns.<br>Alternative approaches.<br>Evaluations.<br>Critiques.<br>Design tradeoffs.<br>Domain knowledge.<br>In other words, it contains training material.<br>Once organizations begin systematically capturing, validating, and distilling those interactions, the economics change.<br>A frontier model interaction is no longer just an inference event.<br>It becomes an asset creation event.
The Difference Between Renting Intelligence and Owning It<br>Historically, expertise accumulated inside people.<br>Organizations attempted to preserve that expertise through documentation, training programs, architecture reviews, design records, and institutional processes.<br>The problem was that much of the knowledge remained trapped inside individuals.<br>AI changes this equation.<br>For the first time, expertise can be transformed into a durable machine-readable asset.<br>The important shift is not that AI can answer questions.<br>The important shift is that AI can convert answers into future capability.<br>Consider what happens when a software architect uses a frontier model to solve a difficult design problem.<br>Under the current model:<br>Question → Answer → Done<br>Under a distillation model:<br>Question → Answer → Validation → Training Asset → Improved Local Model<br>The interaction continues creating value long after the original question has been answered.<br>The resulting model becomes slightly better aligned with the organization, the repository, the architecture, and the developer’s way of working.<br>Repeated thousands or millions of times, the effect compounds.
Foundation Models Optimize for Breadth. Organizations Optimize for Depth.<br>The AI industry often treats model capability as a single dimension.<br>It isn’t.<br>Frontier models are attempting to approximate the entire world.<br>They must understand programming languages, biology, finance, law, mathematics, literature, history, and countless other domains simultaneously.<br>Their objective is breadth.<br>Organizations rarely need breadth.<br>They need depth.<br>A pharmaceutical company needs expertise in pharmaceutical development.<br>A law firm needs expertise in legal reasoning.<br>An engineering organization needs expertise in its codebase, architecture, standards, workflows, and institutional knowledge.<br>The optimization problem is fundamentally different.<br>A specialized model does not need to compete with GPT-6 across every possible domain.<br>It only needs to outperform general-purpose models within the domain that matters.<br>That is a much smaller problem.<br>And smaller problems tend to require smaller models.
The Economics Start to Break<br>This is where the conversation becomes interesting.<br>The current AI boom assumes that increasingly capable models will naturally translate into increasingly valuable inference businesses.<br>History suggests otherwise.<br>Infrastructure businesses rarely become more valuable as the underlying technology becomes cheaper.<br>They usually experience margin compression.<br>Compute becomes cheaper.<br>Inference becomes...
