Implementing effective Large Language Model (LLM) guardrails is crucial for safe and scalable LLM applications. Guardrails are proactive and prescriptive rules designed to handle edge cases, limit failures, and maintain trust in live systems. They ensure that LLMs don't just perform well on paper but thrive safely and effectively in the hands of users. LLM guards protect against vulnerabilities like data leakage, bias, hallucination, prompt injection, jailbreaking, toxicity, and syntax errors. These guards are applied before or after LLM applications process requests to intercept incoming inputs or evaluate generated outputs for safety. To implement effective guardrails, one must choose guards that protect against inputs they would never want reaching their LLM application and outputs they would never want reaching end-users. This includes detecting prompt injection, jailbreaking, privacy breaches, topical restrictions, toxicity, bias, hallucination, syntax errors, and illegal activities. The DeepEval platform offers a comprehensive solution for evaluating and testing LLM applications on the cloud, native to its evaluation framework. By leveraging LLM-as-a-judge and confining it to a binary output, one can generate accurate guardrail scores with greater speed, accuracy, and reliability.
