Foundations & Models
Frontier Model
The term does not denote a technique but a position: the outermost edge of what is currently possible. The frontier shifts every few months, and prices shift with it — what is a top-tier model today is a commodity next year. For companies, the question is therefore rarely what the best model can do, but which model is good enough for their own task.
An example
The gap between the best available model and the best openly available model was at times more than a year and has since shrunk to a few months. For a company building an application, that means: what works today only with the most expensive provider will quite likely run next year on a model that costs a fraction as much — or on your own hardware. Anyone who ties the architecture to it pays twice later.
A closer look
Frontier is a relative designation, not a technical characteristic. It refers to the leading group of models for which there is not yet an open alternative. The gap to open models has been roughly six to eighteen months for some years and is the real strategic value.
Why it matters
The practical consequence is a construction rule, not a forecast: keep the choice of model interchangeable. Concretely, that means prompts, tool definitions and checks do not live in a provider's code but in your own hands, and at least a second model runs alongside in testing. The effort for that is manageable if you plan for it from the start, and considerable if you have to retrofit it. Frontier capabilities are a moving target; your own architecture should not be.
Commonly misunderstood
For most business tasks, the top-tier model is not the right choice. It costs more, responds more slowly, and often does not solve the same task measurably better than a model one tier below.
