Citadel Securities Says AI Is Shifting to Real-Cost Economics as Cheaper Models Displace Premium Frontier Models

Citadel Securities said the early expansion model for generative AI, in which capital subsidized computing power and service fees, is fading. Companies are beginning to factor the cost of each token into procurement decisions. As performance gaps between models narrow, lower-cost options such as DeepSeek are accelerating the commoditization of AI and could reshape how markets value premium frontier models and infrastructure investment.

As of July 20, 2026, the Citadel Securities report said most companies were moving away from using any available AI toward selecting lower-priced models that deliver adequate performance. It said the market would split between a small number of high-end use cases and a large volume of affordable applications. The underlying data did not disclose specific model rates or investment amounts, but identified the actual cost per token as a core metric in corporate AI adoption.
