Fighting LLM Hallucinations

Fighting LLM Hallucinations

A technique to enhance truthfulness without retraining

Adaptive Activation Steering improves LLM truthfulness by manipulating internal model activations to reduce hallucinations.

  • Creates a truthfulness direction in model activation space that can be applied at inference time
  • Works across diverse hallucination categories including fact-based, commonsense, and mathematical reasoning
  • Requires no model retraining or fine-tuning, making implementation practical and efficient
  • Achieves significant reduction in hallucinations while maintaining response quality

This research is critical for security applications where false AI-generated information could lead to misinformation campaigns, compromised decision-making, or exploitation of AI vulnerabilities.
