Harness is Gradually Absorbed by the Model

The “bitter lesson” applied to the age of agents: a general method will eventually win out, but every stretch of the road to that “eventually” is paved with Harness. Example: interruption and insertion of utterances—behavior previously orchestrated by external Harness—is now built into the interaction model. But three reasons why Harness won’t disappear: training takes months (the model will wait, business won’t); the model doesn’t internalize all the constraints of a specific business; each new generation of model opens a new frontier of capability where the model is least stable. Harness migrates with the model to new frontiers.
