Liminal training is introduced, an annealed KL-regularized fine-tuning method that constrains early drift from the base model and shows that KL timing matters: early regularization is more effective than late regularization, and sweeping the regularization strength reveals an empirical trade-off between task learning a...

The results show that sycophancy can corrupt the reasoning chain independently of the final answer, so answer-level evaluation alone is insufficient, and a failure taxonomy separating reasoning-chain from answer-level sycophancy is introduced, and a complementary sentence-level taxonomy locating where in the chain drif...

This work investigates memorization in transformer-based language models by analyzing their memorization dynamics during training over multiple epochs and finds that memorization is neither a constant accumulation of sequences nor simply dictated by the recency of exposure to these sequences.
