Title: Self-Improving Pretraining: using post-trained models to pretrain better models
Abstract:
arXiv:2601.21343v3 Announce Type: replace-cross Abstract: Large language models are classically trained in stages: pretraining on raw text followed by post-training for instruction following and reasoning. However, this separation creates a fundamental limitation: many desirable behaviors such as safety, factuality, overall generation quality, and reasoning ability are only added at a late stage, even though the patterns learned earlier strongly shape a model's capabilities. To tackle this issue
