Representational Stability of Truth in Large Language Models

arXiv — cs.CLTuesday, November 25, 2025 at 5:00:00 AM
  • Recent research has introduced the concept of representational stability in large language models (LLMs), focusing on how these models encode distinctions between true, false, and neither-true-nor-false content. The study assesses this stability by training a linear probe on LLM activations to differentiate true from not-true statements and measuring shifts in decision boundaries under label changes.
  • Understanding representational stability is crucial for improving the reliability of LLMs in factual tasks, as it sheds light on their internal mechanisms for processing truth. This research could lead to advancements in how LLMs are trained and evaluated, enhancing their performance in real-world applications.
  • The exploration of representational stability aligns with ongoing discussions about the limitations of LLMs, including their susceptibility to generating hallucinations and the influence of training data on their outputs. As researchers seek to refine LLM capabilities, issues such as off-policy training data and the impact of spurious correlations remain critical to address.
