Process Reward Model

Definitions

1. A reward model that evaluates the quality of intermediate reasoning steps or process traces rather than scoring only the final answer. Process reward models are explored as a way to encourage better reasoning behavior and reduce shortcut solutions.

   In plain English: A reward model that scores how the AI works through a problem, not just the final result.

   Example: "They tested a process reward model so the system would get credit for sound intermediate reasoning even when final wording varied."
