LLM evaluation still feels manual not scalable

Evaluation feels manual when teams rely too much on human review and too little on structured scoring. Humans are good at spotting nuance, but they do not scale well when the system produces thousands of outputs or multiple versions need comparison.

The challenge is not just volume. It is consistency. Different reviewers often judge the same answer differently unless the rubric is very clear and the examples are tightly defined.

Scalable evaluation usually combines automated checks with targeted human review. That approach keeps the process practical without losing the judgment needed for tricky edge cases.
