Teacher Should Think Ahead: Adaptive Continuations for Reliable On-Policy Distillation

This work identifies Teacher Uncertainty Contraction (TUC), a systematic phenomenon whereby the teacher's predictive uncertainty decreases as it continues from a student-generated prefix, and proposes Adaptive-Continuations On-Policy Distillation (AC-OPD), which augments informative states along student rollouts with t...

CAMFT: Conflict-Aware Mergeable Fine-Tuning for Large Language Models

CAMFT is proposed, a Conflict-Aware Mergeable Fine-Tuning method that makes task adaptation both efficient and mergeaware and treats mergeability as a property shaped during fine-tuning, rather than only a problem to be solved after fine-tuning.

Beyond Correctness: Benchmarking and Aligning Response Behaviors in Hybrid-Thinking MLLMs

Experiments on Qwen3-VL-4B and Qwen3-VL-8B show that incorporating pattern-specific penalties into reinforcement learning can mitigate cross-mode misalignment while incurring a marginal task performance trade-off.
