## Summary

A new framework called Counterfactual Neighborhood Risk Fields (CNRF) has been developed to enhance the safety of vision-language models (VLMs). This innovative approach focuses on distinguishing harmful inputs from benign ones by utilizing context-matched counterfactual pairs. The CNRF framework not only improves risk assessment but also achieves high defense success rates, ensuring that the utility of the model is preserved while enhancing its safety features. This research represents a significant step forward in making VLMs more reliable and secure for various applications.

## Key takeaways
