When selecting an AI model for an application, it's crucial to move beyond general benchmarks and focus on task-specific success metrics and cost. The author suggests defining concrete success criteria for a feature, such as generating an accurate downloadable report, and then measuring how often different models achieve this specific outcome. Public benchmarks like Stanford's HELM can help shortlist models based on capabilities like tool calling and context window, but final evaluation should involve running candidates through the application's actual workflow, considering the model, instructions, tool definitions, and surrounding code.
