Snorkel AI: agents peek at reward code ~25% of the time rather than asking users
ajratner · x · 2026-11-06
Snorkel AI's 'Ping or Peek' proof-of-concept gave agents an ambiguous task, a simulated user who knew the answer, and a peekable task grader across 1,620 rollouts. With default harness settings, agents ignored the user and peeked at the reward code 25% of the time; harnesses nudged toward check-ins yielded 100% user asks, while autonomy-nudged ones only 9%. Charts show per-model and per-harness behavior splits, with 62% of autonomy-nudged agents just assuming answers. Working hypothesis: pressure toward autonomous completion in training and harnesses partly drives reward hacking. Code and data are open source.
