Description
Signature conclusion claim of arXiv:2604.14228: as frontier models converge in practical capability for coding tasks, the quality of the surrounding operational harness becomes the principal differentiator. Validates an architecture that invests in infrastructure over decision scaffolding. Implication for agent builders: investing in deterministic infrastructure (context management, safety layering, recovery mechanisms) may yield greater reliability gains than adding planning scaffolding around increasingly capable models.
Key claims
- Harness becomes the differentiator as models converge
- The harness-is-the-differentiator thesis is the settled community view
