The premise
Off-the-shelf benchmarks miss your domain; AI scaffolds a custom eval harness that tracks what matters.
What AI does well here
- Draft eval categories from sample inputs
- Generate adversarial test cases
- Format a scoring rubric
What AI cannot do
- Replace human grader judgment on subjective tasks
- Predict performance on inputs you didn't sample
Understanding "AI and Eval Harness Design: Building Your Own Test Set" in practice: AI is transforming how professionals approach this domain — speed, precision, and capability all increase with the right tools. AI helps creators design a custom eval harness so model quality is measured against their actual use cases — and knowing how to apply this gives you a concrete advantage.
