Predictable Scaling in GPT-4
Predictable scaling relies on developing deep learning infrastructure and optimization methods that ensure model behavior follows consistent mathematical trajectories across multiple orders of magnitude. In the training of GPT-4, aspects of final performance—such as codebase next-word prediction loss and coding problem pass rates—were accurately predicted prior to full training by fitting power-law scaling functions to smaller models trained with as little as 1/1,000th the compute budget.

A research team is training a 10-billion parameter language model. After consuming 25% of their total compute budget, they observe that the model's performance improvement, when plotted against the compute used, is tracking perfectly along the curve predicted by established scaling laws. However, this predicted trajectory indicates that the model will fall short of its target performance goal by the time 100% of the budget is used. Based on the predictive utility of scaling laws, what is the mos
