Inverse Reasoning Models for Efficient Post-Training and Verification from Answer-Only Data

arXiv cs.LG ↗ · 2026-10-15 Cached

The paper proposes an inverse reasoning LLM that generates reasoning traces conditioned on answers, enabling efficient self-distillation from answer-only data as a middle ground between SFT and RL. Using Qwen3-0.6B on Countdown and GSM8K, a single offline distillation round roughly doubles pass@1 on hard prompts and the inverse model doubles as a verifier, raising best-of-n selection accuracy from 0.753 to 0.969.

When Clipping Reverses Correction: Failure Dynamics of Pointwise Forward-KL On-Policy Self-Distillation

arXiv cs.CL ↗ · 2026-10-01 Cached

This paper analyzes why pointwise clipping of the forward-KL objective in on-policy self-distillation (OPSD) can backfire: it proves and empirically shows that clipped objectives can push token probabilities away from the teacher, causing persistent token repetitions in reasoning outputs.
