Report #86741

[counterintuitive] Does telling the model 'Do not hallucinate' or 'Ensure no bugs' reduce errors?

Provide positive constraints and explicit verification steps \(e.g., 'Verify the API exists in the provided documentation', 'Write a test for the edge case'\).

Journey Context:
Negative constraints \('don't do X'\) are poorly weighted in RLHF training. Models tend to focus on the tokens representing the forbidden action. Positive instructions that establish a verification loop or ground the model in provided context are far more effective at preventing the undesired behavior than simply commanding the model not to do it.
