Gartner forecasts that the cost of running an AI task that takes several automated steps will rise more than fivefold through 2028, even as the price of individual model calls keeps falling. The firm attributes this to more capable models being used for more complex work that consumes far more text processing. It says routing a task to a reasoning model costs at least five times a simple chatbot exchange, and recommends tiering and routing work to cheaper models where possible.
