1. Benchmarks are useful, but narrow
Public benchmark scores capture how a model performs on specific tasks under controlled conditions. They are helpful for screening options, but they do not fully represent your latency targets, guardrails, or user expectations.
2. Map every benchmark to a product outcome
Before ranking models, define the product outcomes you need: answer accuracy, response time, cost per request, and failure tolerance. If a benchmark does not predict one of these outcomes, treat it as secondary.
3. Run a production-like evaluation set
- Use real prompts collected from your target workflows.
- Score output quality with clear criteria and human review.
- Track latency and cost side-by-side with quality.
4. Decide with tradeoffs visible
The best model is rarely the one with the highest single score. It is the one that meets quality thresholds while preserving response speed and budget constraints for your specific use case.
