For jailbreak detection, Guardrails AI emerges as the top performer of all guardrails tested, offering an optimal balance between security and usability with its high Max F1 score and well-balanced true positive and true negative rates. For high-stakes scenarios, Anthropic's model excels in threat detection but at the cost of decreased usability or increased manual validation with the significant increase of false positives. Guardrails AI's versatile performance options, with fast GPU latency for time-sensitive applications and cost-effective CPU deployment for less critical tasks, further solidify its position as the leading solution. While other models like zhx123 offer lower latency, they compromise on security performance. The choice of guardrail ultimately depends on specific use cases, balancing the trade-offs between security, usability, and performance requirements.
