  1. Mismatch Matters: On-Policy Distillation Beyond Token Agreement

    Source note · Aug 10, 2026 · mathematical reasoning, on-policy distillation

    Researchers present TIDE, a new method to address a failure mode in on-policy distillation (OPD) called degenerate agreement. This issue arises when students exploit repetitive loops to achieve high token agreement…

  2. Mask-Aware Policy Gradients for Diffusion Language Models

    Source note · Jul 16, 2026 · reinforcement learning, language models, diffusion models

    The paper presents a method for improving the performance of large language models in tasks like mathematical reasoning and coding by using reinforcement learning. This method addresses the challenge of extending…

  3. AIMO Interpretability Challenge

    Source note · Jul 15, 2026 · ai, robustness, interpretability

    The AIMO Interpretability Challenge is a competition proposed by researchers aimed at distinguishing robust from spurious reasoning in advanced mathematical language models. The challenge focuses on evaluating the…

  4. TREK: Distill to Explore, Reinforce to Refine

    Source note · Jul 6, 2026 · artificial intelligence, policy optimization, mathematical reasoning

    TREK is a procedure that uses distillation for exploration support expansion to improve policy optimization on tasks where the current policy stalls on hard prompts. It identifies low-performing prompts, generates…
