Jailbreak

The Jailbreak metric detects sophisticated attempts to bypass an LLM’s safety filters by reframing unsafe requests as fiction, hypotheticals, multi-turn traps, or encoded payloads. Unlike prompt injection, which focuses on system override, jailbreaks exploit model behavior through creativity, subversion, or ambiguity.

This metric is essential for evaluating robustness against red-teaming and adversarial misuse in public-facing or agentic LLM systems.

When to Use

Apply the jailbreak metric in:

• Chat assistants or agent stacks vulnerable to roleplay or multi-step deception
• Tools with multiple system safeguards users may attempt to chain through
• Evaluations of filter evasion resilience
• Model monitoring pipelines tracking real-world misuse patterns

Score

The API returns a score (float, 0.0 – 1.0) under the jailbreak key.

• 1.0: No signs of roleplay, obfuscation, or adversarial framing.
• 0.7–0.99: Light hypothetical or fictional language with ambiguous intent.
• 0.2–0.7: Chained, multi-turn, or encoded unsafe behavior.
• 0.0–0.2: Active bypass of filters through staged or disguised means.

A higher score is better. A lower score indicates an adversarial jailbreak attempt.

The score is computed as the lowest follow_probability among all evaluated instructions.
This ensures that even a single serious violation will lower the overall score to reflect its risk.
