The blog post discusses the inherent unpredictability and control challenges of deploying Large Language Models (LLMs) due to their stochastic nature, which makes deterministic outputs unattainable and prompts insufficient for ensuring reliability. It highlights the importance of implementing LLM guardrails to prevent the generation of harmful or biased content and to maintain compliance with developer and stakeholder guidelines. Various vulnerabilities such as training data poisoning, prompt injection, DOM-based attacks, denial of service, and data leakage are explored, along with strategies to mitigate these risks using no-cost safeguards, advanced validations, and LLM-in-the-loop techniques. The use of Guardrails AI, a framework for building secure AI applications, is emphasized as a method for setting up guidelines to ensure data integrity and application safety. The article also covers the implementation of rule-based data validation, advanced metric-based validations, and LLM-based guardrails to handle complex vulnerabilities, providing examples and tools for securing LLM deployments effectively.
