Pre-Training

The initial, expensive phase of training where a model learns general patterns from a massive dataset.

Definition

The initial, expensive phase of training where a model learns general patterns from a massive dataset. For language models, this typically means next-token prediction on trillions of tokens scraped from the internet. Pre-training gives the model broad knowledge that fine-tuning later specializes.
