100 AI Model Training Dataset Size = 250% Annual Growth Over Fifteen Years, per Epoch AI Note: In AI language models, tokens represent basic units of text (e.g., words or sub-words) used during training. Training dataset sizes are often measured in total tokens processed. A larger token count typically reflects more diverse and extensive training data, which can lead to improved model performance – up to a point – before reaching diminishing returns.
