Increased LLM Vulnerabilities from Fine-tuning and Quantization

The article discusses the vulnerabilities of Large Language Models (LLMs) to various attacks such as jailbreaking, prompt injection, and privacy leakage. It highlights the use of adversarial and alignment training in foundational LLMs to prevent the generation of malicious content. However, when these foundational LLMs are fine-tuned or quantized for specialized use cases, their vulnerability increases, particularly reducing their resistance to jailbreaking.

The research tested foundational models like Mistral, Llama, MosaicML, and their fine-tuned versions, and found that fine-tuning and quantization significantly increased LLM vulnerabilities. The article concludes by emphasizing the importance of external guardrails in reducing these vulnerabilities.

Key takeaways

Large Language Models (LLMs) are vulnerable to different types of attacks, including jailbreaking, prompt injection attacks, and privacy leakage attacks.
Foundational LLMs undergo adversarial and alignment training to avoid generating malicious and toxic content.
Fine-tuning and quantization of foundational LLMs for specialized use cases can reduce jailbreak resistance and increase LLM vulnerabilities.
External guardrails can be useful in reducing LLM vulnerabilities.
