Training

The process of adjusting model parameters by learning statistical patterns from large datasets.

Illustrative conversation

  1. Do we need to retrain the model whenever our API documentation changes?
  2. Usually no. Retrieval can place the current documentation in context without changing the model's parameters.

Definition

Training is the optimization process that adjusts a model's parameters so its predictions better match examples or objectives in a dataset. Pre-training builds broad capabilities from large corpora, while later stages such as fine-tuning specialize behavior. Supplying a document in a prompt is not training: it changes the context for one inference request without updating the model's weights.
