Databricks: the harness matters as much as the model
toptickcrypto · x · 2026-07-20
A Databricks article argues that harnesses can dramatically change model efficiency.
In tests using the same model with the same thinking effort, the cost per task differed by more than 2x in some cases while quality stayed roughly the same. The main reason was how much context each harness fed the model on every turn. The chart also shows Pi sending about 3x less context per turn and finishing tasks in fewer runs.
