Safeguard evaluation

Definition

A safeguard evaluation tests whether an AI safeguard actually works against the risk it targets, for example by red-teaming a misuse classifier, running jailbreak bug bounties or measuring how often harmful requests get through and harmless ones get blocked.

Also called: Safeguards evaluation, Safeguard efficacy assessment, Safeguards assessment, Safeguard red-teaming

NIKOLAI's proposed operational definition

NIKOLAI proposes a Safeguard evaluation record as: a test of whether a safeguard, or a set of safeguards, works as intended against the risk it targets, carrying the method (automated evaluation, internal or external red-teaming, bug bounty), the attacker assumed, the metric (coverage, robustness, effect on benign use, time to patch), the result and who ran it. It differs from a capability evaluation, which measures what the model can do. This is an unsourced NIKOLAI editorial synthesis.

The operational definition is CASRAI's own proposal, not a definition any named organisation has agreed to. See what NIKOLAI is and is not, or browse the AI safety glossary.

Examples

Examples from published documents

  • OpenAI commits to "moving beyond the flawed approach of re-running capability evaluations on the safeguarded model and towards a more thorough assessment of each safeguard and its efficacy" (OpenAI Preparedness Framework v2, Appendix A)
  • Anthropic: "We pay up to $35,000 per novel universal jailbreak identified." (Anthropic Risk Report, August 2026, §4.5.3.1)

Counter-examples

Not to be confused with

  • A dangerous-capability evaluation measures what a model can do with safeguards removed; a safeguard evaluation measures whether the safeguards stop that capability being reached.

Terms defined under this element that are not NIKOLAI elements themselves, each as the cited document uses it. Every term is also listed in the AI safety glossary.

Safeguards report
A safeguards report compiles the evidence that a model's safeguards sufficiently reduce severe risk: the ways the risk could be realised, the safeguards mapped to each, their measured efficacy, the residual risk and known limitations. OpenAI and Anthropic both use the term.
Source: OpenAI Preparedness Framework v2
Model safety bug bounty
A model safety bug bounty pays outside researchers for finding ways to bypass a developer's safeguards, especially universal jailbreaks. Anthropic runs one through HackerOne against its biology classifiers and pays up to $35,000 per novel universal jailbreak.

Every row below is a shadow mapping. A shadow row is CASRAI's own reading of a published document. No lab, evaluator or regulator named on a shadow row has declared, endorsed, or been consulted on it. That changes only when an organisation files its own Mapping Declaration.

Pointers that are not crosswalk claims

These sources mention this concept but do not define or map it clearly enough to count as a crosswalk row — noted here so the research is visible without overstating it as a mapping.

  • UK AI Security Institute (AISI)

    OpenAI reports: "In all rounds thus far, UK AISI identified universal jailbreaks in the cyber domain, including jailbreaks that allowed for long-form agentic task completion in domains like vulnerability discovery and exploit development." External safeguard testing reported by the developer, not by AISI.
