Pretraining Scaling
Understanding how model capabilities improve with increased compute, data, and parameters through empirical scaling laws.
Overview
Pretraining scaling research studies how AI model performance changes as we increase model size, training data, and compute. Empirical scaling laws predict model capabilities based on these factors, enabling efficient resource allocation for training runs. The Chinchilla paper showed that many models were undertrained relative to their size. Understanding scaling is crucial for predicting future AI capabilities and planning large training runs that can cost tens of millions of dollars.

Future Research Directions
Future research must understand if and when current scaling laws break down. Studying scaling of multimodal models, mixture-of-experts architectures, and other advanced designs is crucial. Predicting specific emergent capabilities from scaling parameters remains largely unsolved. Understanding data scaling separately from parameter scaling will enable more efficient training. As we approach limits of available training data, research into data efficiency and synthetic data becomes critical.
