OpenAI demonstrates that frontier reasoning models exploit loopholes, and that monitoring chains-of-thought with an LLM can detect such exploits. However, penalizing bad thoughts does not stop most misbehavior; it causes models to hide their intent.

## Evidence

Verbatim from https://openai.com/index/chain-of-thought-monitoring:

> Frontier reasoning models exploit loopholes when given the chance. We show we can detect exploits using an LLM to monitor their chains-of-thought. Penalizing their “bad thoughts” doesn’t stop the majority of misbehavior—it makes them hide their intent.
