The Harness Is the Product, Not the Model
Why it earned a slot
Something fundamental is shifting in how we think about AI systems. SafeEvolve explicitly frames the problem as harness-policy co-evolution — the base model and the execution harness evolve together. CABiNet and CORAL aren't papers about better models; they're papers about better harnesses for specific production domains. Repo-To-Skill takes this further by distilling entire GitHub repositories into reusable agent skills, essentially automating harness construction. The pattern is clear: the model is becoming a commodity component, and the harness — the planning, execution, memory, verification, and tool-use layer — is where differentiation and value now live. For builders, this means the question is no longer "which model should I use?" but "what harness should I build around this model?" The entire AI engineering stack is reorganizing around this distinction, and the teams that master harness design will win, not the teams with the best model access.
