LLM · Evaluation and Model Selection

Build an auditable decision process from capability metrics to model selection for real applications.

Define tasks and scoring criteria before comparing candidate configurations. Distinguish model capability from agent-system scores, success at least once from reliability across repeated runs, and token prices from cost per successful task. Brand labels and individual leaderboards cannot replace acceptance testing.
