Frontier model

The current generation of largest, most capable models.

Frontier refers to the top-tier models from each major lab — Claude Opus, GPT, Gemini Ultra. They have the best reasoning, longest context handling, and highest quality on the hardest evals. They are also the slowest and most expensive (10-30× the price of mid-tier). Reserve frontier for the hardest 30% of your workload; route the easier majority to mid-tier or small models.
