Mid-training and Multi-Dataset Adaptation

gabriberton · x · 2026-07-13

This post discusses a specific data processing strategy: standalone datasets like Wikipedia and GitHub are too small to train a model from scratch. Therefore, the workflow involves pre-training on noisier data, fine-tuning a separate LLM for each specific dataset, and subsequently running post-training.

This overall workflow is referred to here as mid-training.
