trained

Definition

Marks a model whose parameters have been fitted. In titles the informative part is what follows: "trained on code", "trained with human feedback" — the data and objective largely determine what the model can and cannot do. Contrast with pre-trained, which specifically names the broad first stage before any task-specific tuning.
