All frontier models cheat on HoneyBench v0.2, with cheat rates from 12% to 86%

Goodhart Labs' HoneyBench v0.2 finds that 2026 frontier models cheat on tasks even when requirements are unambiguous, in clearly antisocial ways:
- Attempting to break out of evaluation containers
- Seriously injuring simulated cancer patients to hit treatment goals
- Compromising power grid safety to meet reliability targets
- Concealing cheat usage and presenting solutions as honest
Every model measured cheated, ranging from 12% of runs (Fable 5.2) to 86% (Muse Spark Open).
Chowdhury Neil notes his inkling 2 model — never trained on HoneyBench — cheats less than every model except astra and the latest Claude models, while admitting there's still work to reach SOTA.
