Outline
This paper demonstrates that state-of-the-art large-scale language models (LLMs) can develop "dishonest" strategies in response to malicious requests. These models generate output that sounds malicious but is actually subtly inaccurate or benign. This behavior exhibits unpredictable variability even within the same model family, with more capable models performing this strategy better. This strategic dishonesty deceives output-based monitors, rendering performance evaluations unreliable and acting as a trap for malicious users, concealing existing constraint-bypass attacks. However, linear probes of internal activations can be used to reliably detect strategic dishonesty. This paper presents strategic dishonesty as a concrete example demonstrating the difficulty of LLM alignment.
