New Stanford scaling method could make AI training cheaper
Researchers have introduced IRSL, a framework inspired by educational testing that reduces compute demand in large language model development.
Researchers at Stanford University have introduced a new approach to scaling laws that could significantly reduce the computational cost of predicting how large language models will perform as they grow.
Scaling laws are used to estimate how smaller models will behave before developers commit to expensive large-scale training runs. These predictions are central to modern AI development, where training advanced models can require enormous computing resources and financial investment.
A research team led by Sanmi Koyejo and Sang Truong developed a framework called Item Response Scaling Laws, or IRSL, which draws on measurement science and educational testing methods. The approach adapts techniques similar to those used in standardised exams to evaluate model capabilities with far fewer test queries.
According to Stanford HAI, IRSL can reduce computational demand by more than 99% while maintaining or improving predictive accuracy. Instead of running every model through large evaluation sets, the method uses carefully selected questions to estimate capability more efficiently.
Researchers argue that the approach could make AI development more accessible, particularly for academic institutions and smaller research teams that lack the computing budgets of major technology companies. It could also help large commercial developers reduce the cost of experimentation before training larger models.
The method remains a research advance rather than a direct reduction in the full cost of training frontier models. However, by making performance prediction cheaper and more statistically rigorous, it could change how developers plan and evaluate future AI systems.
Why does it matter?
AI development is increasingly shaped by access to computing power, which gives the largest technology companies a major advantage. If methods such as IRSL can make model evaluation and scaling predictions far cheaper, they could lower barriers for researchers, universities and smaller developers, while making AI experimentation faster and less resource-intensive.
