Amazing work!.
A good language model should say “I don’t know” by reasoning about the limits of its knowledge. Our new work AbstentionBench carefully measures this overlooked skill in leading models in an open-codebase others can build on!. We find frontier reasoning degrades models’ ability to

Please check out our work on steering internal representations to detect LLM hallucinations!.
🚨 If you care about reliable, low-cost LLM hallucination detection, our #ICML2025 paper offers a powerful and data-efficient solution. 💡We introduce TSV: Truthfulness Separator Vector — a single vector injected into a frozen LLM that reshapes its hidden space to better
