Bad Guy Tokens.

LessWrongAnalysis or commentary·
AI brief

A recent paper found that training models to give bad advice in a narrow domain does not make the model or its persona broadly evil in a robust way; it only makes the specific fine-tuned system prompt tokens evoke an evil persona.

Why it matters: It suggests that narrow fine-tuning for harmful behavior may not generalize into broadly malicious model behavior.
