  "summary": "Process supervision trains AI to show correct reasoning steps rather than just final answers, achieving 15-25% absolute improvements on math benchmarks while making reasoning auditable. However, it shares RLHF's fundamental limitation: humans cannot verify superhuman reasoning steps, and models might maintain separate internal reasoning from visible chains.",
