Red-team exercise

Definition

A red-team exercise is a structured attempt by experts or automated tools to make an AI model behave harmfully or to get around its safeguards, using techniques a real attacker might use, so that weaknesses can be found and fixed before or after release.

Also called: Red teaming, Red-teaming, Adversarial testing, Red-teaming engagement

NIKOLAI's proposed operational definition

NIKOLAI proposal: an evidence-gathering exercise in which people or automated systems adversarially probe a model or its safeguards to elicit harmful behaviour or find ways around protections, recorded with who performed it (internal, third-party, automated), its target (model capabilities, deployment safeguards, or weight security), the model version and safeguards in place, its duration or compute effort, and how findings were scored and remediated.

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 used automated red-teaming to search for universal jailbreaks, with optimisation-based search, reinforcement learning and test-time search totalling over 700,000 A100e GPU hours of compute (GPT-5.6 system card, section 9.4.4)
  • Four private red-teaming organisations tested GPT-5.6 for more than a month from 3 June 2026, and OpenAI states that all findings were mitigated before launch (GPT-5.6 system card, section 9.4.5)
  • Google DeepMind's CBRN red teamers each work on harm-journey sub-stages matching their expertise, use a model version without out-of-model safeguards, and score findings with a sub-stage rubric (Gemini 3.7 Flash FSF report, p.9)

Counter-examples

Not to be confused with

  • Running a fixed set of known jailbreak prompts automatically is a benchmark of jailbreak robustness, not a red-team exercise, unless attackers adapt their strategy to the model during testing.

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.

Jailbreak
A jailbreak is an adversarial prompt or technique designed to get around an AI model's refusal training or safeguards and obtain harmful help that the model would normally decline to give.
Source: GPT-5.6 deployment safety card
Automated red teaming
Automated red teaming uses algorithms, such as optimisation-based search, reinforcement learning or test-time search, instead of human testers to discover attacks on an AI model and its safeguards at scale.
Source: GPT-5.6 deployment safety card
Expert red teaming
Expert red teaming uses domain specialists, such as virologists or security professionals, who probe an AI model for dangerous information in their field and score what they obtained against a rubric.
Source: Gemini 3.7 Flash FSF report
Bug bounty
A bug bounty, in AI safety, is a programme that rewards outside researchers for reporting ways to break a model's safeguards, such as working jailbreaks, giving developers continuing evidence about how robust their protections are.

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.

  • METR

    "A METR staff member spent three weeks red-teaming a subset of Anthropic's internal agent monitoring and security systems, discovering several novel vulnerabilities." A bounded third-party red-team engagement on monitoring, recorded as a pointer (see also N10 embedded-evaluation).

Divergence

Where sources materially disagree

Frameworks point red-teaming at three different targets: model capabilities (Google DeepMind's expert CBRN red teaming against a model without out-of-model safeguards), deployment safeguards (OpenAI's automated and third-party jailbreak red-teaming; Anthropic's red-teaming and bug bounties for assessing the threat of jailbreaks), and model-weight security (Google DeepMind's APT-simulating red-teaming; Microsoft's advanced security red teaming). A record needs to say which target was tested, because a pass on one says nothing about the others.

Gap

The research did not find a shared minimum for red-team duration, team composition or compute effort; OpenAI reports such figures for its own exercises (four organisations, more than a month, over 700,000 A100e GPU hours), but no common reporting format was found.
