AI BriefingSafety Is a Given, Cost Savings Are a Bonus: Why AI Services Need Dedicated Guardrails
Key point
AI services need a separate, dedicated guardrail system to compensate for the limitations of the system prompt approach.
Details
Guardrails are safety mechanisms that control AI so it doesn't operate in unintended directions or break rules. Their core purpose is to prevent Prompt Injection or Jailbreaking attacks in which users deliberately try to make the AI ignore its rules.
The method mainly used today is embedding strong rules in advance into the System Prompt. This has the advantage of being simple and intuitive to implement, but recent research shows this approach can cause serious side effects.
When guardrails are included in the system prompt, a phenomenon occurs where the model's Embedding skews in a particular direction. This leads to a problem of Excessive Refusals, where the model refuses to answer not only harmful questions but also harmless ones.
To solve this, a Separate Guardrails system, kept apart from the AI model, is needed. This approach works by installing security gates before and after the model, and performs the following functions.
- Tripwires: Immediately block a request when a dangerous input or output is detected.
- Rewriter: Modify the input in a safe direction before passing it to the model.
