Training data

Updated Feb 5, 2025

Definition

Training data is the information used to train an AI model before it is deployed, forming its general knowledge.

Plain English

It's what the model learned from in the past, not what it "looked up" today.

Why it matters

  • Training data can be outdated.
  • Without browsing, answers may rely more on past knowledge.
  • You shouldn't assume "existing on the web" means "in the model."
