Book-level organization boosts synthetic textbook data for LLM training

Researchers have developed a new method for creating synthetic textbook data that significantly improves language model training. This approach organizes related content into coherent book-level documents, a factor previously overlooked in favor of local rewriting. The pipeline generates over 686,000 textbooks, leading to a 1.09 average performance improvement on downstream tasks. Experiments showed that book-level organization, rather than just content or length, was key to this performance gain, outperforming random concatenation and independent section rewriting. AI

IMPACT This research suggests a new avenue for improving LLM training data, potentially leading to more capable models with less computational cost.

    Beyond Rephrasing: Book-Level Organization Improves Synthetic Textbook Data for Mid-Training

    arXiv:2607.28109v2 Announce Type: replace Abstract: Synthetic textbook data has improved language model pre-training, but prior work largely treats the benefit as a property of generated content or local rewriting style. We study a different factor: whether related content is org…
