Researchers introduce Distill to Detect (D2D), a method for exposing hidden preferential biases in language models by distilling the distributional shift between a suspected model and its base into a KV-cache prefix adapter (cartridge), amplifying the bias signal into generated text. The work addresses a fundamental asymmetry in bias detection: stealth biases introduced anywhere in a model's supply chain can remain invisible to text-based inspection, weight analysis, or representation probing. D2D is grounded in a theoretical framework based on Fisher-weighted projection of logit distribution shifts and is validated across multiple bias types. The technique offers a practical auditing tool for detecting hidden behaviors in deployed LLMs.
