  1. Reason Only When Needed: Efficient Generative Reward Modeling via Model-Internal Uncertainty (2026 · 8 citations)
    Generative reward models (GRMs) judge LLM outputs using chain-of-thought (CoT) reasoning. They have two weaknesses. They spend reasoning effort on every input, including easy ones. They also pick among sampled reasoning chains by voting, which cannot separate sound chains from ones that only look convincing. The…
  2. Why Supervised Fine-Tuning Fails to Learn: A Systematic Study of Incomplete Learning in Large Language Models (2026 · 6 citations)
    Supervised fine-tuning (SFT) is usually treated as a reliable way to specialize LLMs. The authors show, however, that converged models still get part of their own training set wrong. They call this the Incomplete Learning Phenomenon (ILP), distinguish it from catastrophic forgetting and machine unlearning, and…
  3. ToolSafe: Enhancing Tool Invocation Safety of LLM-based agents via Proactive Step-level Guardrail and Feedback (2026 · 3 citations)
    LLM agents that call external tools can be steered into harmful actions, either by malicious users or by prompt injections hidden in tool outputs.
  4. Learning from Contrasts: Synthesizing Reasoning Paths from Diverse Search Trajectories (2026 · 1 citation)
    Search-based data generation with Monte Carlo Tree Search (MCTS) usually keeps only the best-scoring solution path and throws away the rest.
