Static benchmarks rarely reflect what your customers do on Tuesday afternoon. We ship evals inside the product surface so signal keeps flowing while features evolve.
The cadence we run
- Define a handful of task-specific checks for quality, latency, and cost.
- Add inexpensive guardrails and logging to catch drift early.
- Review failures with product + engineering each week, then ship fixes in the next sprint.
Why it works
The loop is small, so teams actually do it. And because the evals are close to real usage, they reveal regressions that synthetic tests miss — long before support tickets pile up.
