arXiv:2606.04612v1 Announce Type: new Abstract: Large Language Models (LLMs) are vulnerable both to hallucination and adversarial manipulation. Although these problems are closely related, existing defences typically address them separately. We investigate a hybrid defence framework that combines entropy-based models, designed to reduce hallucinations, with uncertainty-based models and geometric-based models, designed to reduce vulnerability. Under in-domain tests on Natural Language Understanding datasets (FEVER, HotpotQA, CSQA, SIQA) we find our hybrid model improves both clean-task performa
The increasing deployment of LLMs across critical applications is making their vulnerabilities to hallucination and adversarial manipulation a pressing concern, driving immediate research into robust defenses.
This development is crucial for ensuring the reliability and trustworthiness of AI systems, particularly as LLMs are integrated into more sensitive and autonomous functions.
The introduction of a hybrid defense framework suggests a more integrated and potentially more effective approach to mitigating core LLM vulnerabilities, potentially accelerating their safe deployment.
