Identifies LLM models by password bias patterns when they refuse to tell you.

Strengths
  • Novel fingerprinting technique bypasses model identity lies during red team assessments.
  • Achieves 92% identification accuracy with just five generated password samples.
  • Practical red teaming tool for opaque API deployments where models hide identity.
Weaknesses
  • Limited to text generation biases, may degrade as models improve randomness.
  • Requires maintaining pattern database as new models release.
