Anthropic on the Thinning of Harnesses

xiaohu · x · 2026-07-19

The article discusses the trend of the **harness wrapped around models thinning out**. In the past, many external processes hardcoded rules based on what models couldn't do, but as capabilities improve, these assumptions quickly become outdated. The author compares the old harness to a fixed assembly line where every station's task and handoff are pre-arranged. The new external logic, however, acts more like a 'coach' rather than an 'assembly line,' focusing less on locking down steps and more on dynamically deciding formations and organizing model collaboration based on the task.
