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.

What changed

Falling model prices were expected to bring overall AI running costs down.

  • over 5x cost rise per workflow by 2028
  • at least 5x vs basic chatbot call
