Key insights
Concrete technical or product signals.
- Run provider-specific evals before standardizing; public benchmarks rarely capture your tool stack, latency targets, and failure costs.
- Route by task difficulty and governance constraints rather than sending every request to the newest flagship.
Use cases
Where this shines in production.
- Model selection for production assistants
- Agentic coding and tool-use evaluations
- Provider routing and procurement decisions
