Questions

What is AI red teaming?

AI red teaming is a deliberate attempt to make a model or AI application produce harmful, unsafe or unintended output. Testers use jailbreaks, manipulative prompts and misuse scenarios. 56 published entries state red teaming and adversarial testing.

What is the purpose of red teaming an AI system?

Red teaming finds failure modes before users or attackers do, so they can be fixed or guarded. The findings also feed regression tests and the risk documentation that regulation and internal policy ask for.

How does AI red teaming differ from AI penetration testing?

Red teaming targets the model's behaviour, such as harmful content and policy bypass. Penetration testing targets the system around the model: tools, data access, integrations and prompt injection that triggers actions. 33 published entries state both.

What risks does an AI red team assessment look for?

Typical risks are jailbreaks, harmful or illegal content, leakage of system prompts or private data, biased output, misinformation and unsafe actions by agents. Reports often map findings to the OWASP Top 10 for LLM Applications or MITRE ATLAS.

Which AI systems should be red teamed: models, applications or agents?

All three, at different depths. Model red teaming tests behaviour; application red teaming adds the system prompt, retrieval and user interface; agent red teaming adds tools and permissions, where a successful attack can cause actions.

What is the difference between automated red teaming tools and human-led red teaming services?

Tools run large sets of known attack prompts quickly and repeatably. Human-led services design new attacks for the specific product and judge subtle failures. This directory lists services; tool-only vendors are on the not-published page.
