CAT-alyzing Honesty: Continuous Adversarial Training for Transferable LLM Honesty

We introduce Continuous Adversarial Training for Consistent Honesty (CATCH), inspired by a method originally developed to robustly refuse harmful queries.

Key points

  • Large language models (LLMs) are becoming prevalent in scenarios where honesty is critical.
  • CATCH trains the model towards an honest answer and away from a dishonest one while maintaining the model's capabilities.
  • We show that trained with only hundreds of targets built from self-reporting scenarios, CATCH learns an honest behaviour that robustly generalizes and transfers across distinct benchmarks.
  • We show that CATCH outperforms prompting and supervised fine-tuning in improving honesty, and it is on par with state-of-the-art honesty activation steering.
