Frontier model
Also known as: frontier
A frontier model sits at the leading edge of what AI can do — the strongest, most capable models, typically from the largest labs.
Traits:
- Closed or gated — you use them via API, not by downloading.
- Massive — trillions of parameters, enormous training.
- Priced — the capability comes at a per-token cost.
The frontier is a moving target; what’s frontier today is last season’s model in a year.
Practical: when a task demands maximum quality and cost doesn't matter, reach for the frontier. For everyday work, a smaller open model is often 90% of the way there for 5% of the price.
