[counterintuitive] A single LLM judge is sufficient for automatic evaluation

Use multiple judges, human baselines, and bias-aware protocols: shuffle answer order, calibrate rubrics, break evaluations into atomic criteria, and report inter-judge agreement.

Journey Context:
Using one LLM to score another is convenient but fraught. LLM judges exhibit position bias, length bias, self-preference, and sensitivity to prompt wording. A single score can hide tradeoffs between helpfulness, safety, and correctness. Reliable automatic evaluation pairs LLM judges with human spot-checks, multiple models, and carefully designed rubrics that separate different quality dimensions.
