Red Teaming
Definition
Red teaming in AI is the practice of adversarially testing systems to discover failures, vulnerabilities, and harmful behaviors before deployment, simulating how malicious users might exploit the system.
Why It Matters
Standard evaluation tests how well systems work. Red teaming tests how badly they can fail. If you only test the happy path, you’ll be surprised when real users (or attackers) find the edge cases.
AI systems fail in unexpected ways. Models produce harmful content, leak private information, behave erratically on unusual inputs, or get manipulated through prompt injection. Red teaming finds these failures before users do.
For AI engineers, red teaming is essential pre-deployment practice. Every production AI system should be adversarially tested. The cost of finding a failure in testing is vastly lower than finding it from user reports or, worse, media coverage.
Implementation Basics
What Red Teamers Test
Content Safety
- Generating harmful, illegal, or inappropriate content
- Bypassing content filters
- Producing misinformation
Security
- Prompt injection vulnerabilities
- System prompt extraction
- Unauthorized data access
- Jailbreaking safety measures
Robustness
- Edge case inputs that cause failures
- Adversarial inputs designed to confuse the model
- Unusual formatting or encoding
Privacy
- Training data extraction
- PII generation from prompts
- Memorization of sensitive information
Running a Red Team Exercise
-
Define scope: What systems, what types of failures?
-
Assemble team: Mix of internal staff and external testers. Diverse perspectives find more issues.
-
Provide context: Red teamers need understanding of the system, its intended use, and what constitutes failure.
-
Set guardrails: Even red teaming has limits. Define what’s out of scope (e.g., actual infrastructure attacks).
-
Document findings: Clear reproduction steps for each issue found.
-
Prioritize and fix: Rank issues by severity and likelihood. Address critical items before launch.
Red Team Approaches
Manual Testing Human testers try creative attacks. Best for finding novel failures.
Automated Red Teaming Use LLMs to generate adversarial inputs at scale. Covers more ground but may miss creative attacks.
Structured Programs Bug bounties and external researcher programs for ongoing red teaming.
Make red teaming a recurring practice, not a one-time event. Systems change, new attack techniques emerge, and yesterday’s safe model might have today’s vulnerabilities.

Red teaming language models discovers harmful behaviors and outputs that automated safety testing misses, enabling targeted safety improvements.
