The Harness, Not the Architecture, Is Where AI's Long-Term Value Accrues

- A widely shared take argues that the real long-term value in AI accumulates in the harness around the model layer: data, labeling, training paradigms, evals, and inference.
- Model architectures themselves get swapped in and out quickly, offering little durable advantage.
- Teams with better harnesses can train better models on the same architecture at lower time and compute budgets.
- The implication: engineering infrastructure beats one-off model breakthroughs as a moat.
