A new research paper explores the effectiveness of instruction-based suppression in large language models, finding that while models can be trained to avoid expressing prohibited content, the underlying concepts remain recoverable from their internal representations. The study utilized representational probing, attention analysis, and behavioral semantic leakage experiments across various transformer models. Results indicate that prohibited concepts continue to influence attention routing and shape downstream generations even when lexical avoidance is successful, revealing a significant gap between behavioral and representational alignment in these models.

IMPACT Reveals a fundamental gap in LLM safety mechanisms, suggesting current suppression techniques may not fully mitigate risks associated with prohibited content.
