New framework offers formal guarantees for LLM interpretability

A new formal verification framework has been developed to address the fragility of mechanistic interpretability in large language models. Researchers demonstrated that minor input changes can drastically alter the interpretable features identified by replacement networks in models like GPT-2 small, Gemma, Llama, and Qwen. The proposed framework provides a sound upper bound for faithfulness gaps in adversarial scenarios and, when integrated into training, can restore reliable feature-level interpretations for safety auditors.
