How Much Does It Cost to Train Frontier AI Models?
The cost of training frontier AI models has grown by a factor of 2 to 3x per year for the past eight years, suggesting that the largest models will cost over a billion dollars by 2027.
The Rising Costs of Training Frontier AI Models
The costs of training frontier AI models have grown dramatically in recent years, but there is limited public data on the magnitude and growth of these expenses. This paper develops one of the first detailed cost models to address this gap, estimating training costs using three approaches that account for hardware, energy, cloud rental, and staff expenses.
