The premise
AI can explain how AI process reward models grade each reasoning step rather than only the final answer.
What AI does well here
- Compare outcome reward signals to step-level signals on credit assignment
- Walk through tree-search inference using a process reward model as a scorer
What AI cannot do
- Decide which step taxonomies suit your domain
- Replace human evaluation of reasoning quality
