Training Cost
The total expense of building an AI model from scratch, encompassing compute (GPU/TPU hours), data acquisition, engineering talent, and infrastructure — a key barrier to entry in frontier AI development.
Training costs for frontier models have risen exponentially: GPT-3 cost approximately $4.6 million in 2020, GPT-4 cost $78-191 million in 2023, and next-generation models are projected to cost $500 million to $1 billion+. These costs create a concentration of frontier AI development among a few well-funded organizations. However, DeepSeek demonstrated that algorithmic innovation can dramatically reduce costs — training a competitive model for $5.6 million. Training costs include not just compute but also data curation, engineering teams, and multiple experimental runs before the final model.
