Summary

Effective AI red teaming requires:

  1. Systematic testing: Cover all vulnerability categories
  2. Automated generation: Scale testing with adversarial prompt generation
  3. Safety evaluation: Test across all harm categories
  4. Comprehensive reporting: Document findings with remediation guidance
  5. Continuous testing: Integrate into CI/CD for ongoing security

Red teaming should be performed regularly and especially before major deployments to ensure AI systems are resilient against adversarial attacks.
