Getting Language Models to Open Up on ‘Risky’ Subjects
- Many language models exhibit an 'over-refusal' behavior, hindering their ability to engage with sensitive or controversial topics intelligently.
- A new dataset named 'FalseReject' aims to address this issue by retraining models to handle sensitive topics more effectively without sacrificing safety.
- Researchers from Dartmouth College and Amazon developed the FalseReject dataset, containing prompts likely to trigger refusals but are harmless.
- The dataset challenges models to learn a flexible tolerance towards potentially risky prompts, rather than relying on a fixed 'white-list' approach.
- Language models often struggle with over-refusal, impacting their interactions with users on various topics.
- Refusal patterns vary among different model families, with reasoning models like DeepSeek-R1 showing better alignment in handling sensitive prompts.
- The FalseReject dataset includes prompts that challenge models to distinguish between casual inquiry and security research-level queries.
- Open-source models like Mistral-7B and DeepSeek-R1 demonstrate strong performance in handling over-refusal, potentially outperforming closed-source models.
- Training with FalseReject data helps reduce over-refusal in non-reasoning models and enhances safety in reasoning models.
- The new approach emphasizes the importance of balancing safety and engagement in language models, especially in evolving ethical and legal contexts.
