• Closing Thought

• The gap in cost between “frontier” models and “small” models has widened to an astonishing 16x to 30x multiplier, making single-model architectures economically unviable for scaling businesses.

• Enterprise architecture is shifting to Cognitive Routing: using intelligent gateways to analyze incoming queries and direct them to the cheapest model capable of handling the task.

• Techniques like “model cascading” start a task on a nearly free model and only escalate to expensive frontier models when the system detects low confidence or failure.

• This shift moves the competitive moat away from the foundation model providers and into the hands of the routing and orchestration layer.
