AI Safety Research

AntiPaSTO: Self-Supervised Steering of Moral Reasoning | arXiv:2601.07473 | GitHub

  • Gradient-based representation steering using model’s own behavioral consistency as signal
  • Works without preference labels; outperforms prompting on out-of-distribution moral dilemmas
  • Builds on prior representation alignment work that showed promise but suffered from instability

LLM Ethics Leaderboard | Website

  • Evaluation framework for moral reasoning across 12+ frontier models

Eliciting Suppressed Knowledge | GitHub

  • Contrastive prompting to surface RLHF-suppressed knowledge (20% improvement on TruthfulQA)

LoRA Lie Detectors | GitHub

  • Low-rank adapters for deception detection (87% accuracy on held-out set)
