LLM as judge for product managers testing AI outputs

Testing AI manually takes too long, making LLM as judge workflows essential for product managers. An LLM as judge quickly grades AI tools without reading every response. Think of testing AI like tasting wine from a massive delivery. You cannot taste every drop, so you hire a taster to score batches using rules. An automated judge does the same by reading inputs and answers to assign a score. Never trust this judge blindly. A human taster might prefer sweet wine, while an AI judge might equate politeness with complex words. Flawed criteria means high scores for bad outputs, which ruins your product. Always calibrate your system first. Manually grade a small batch and compare your scores against the automated ones. If they align, scale the process. If they disagree, rewrite the rules before automating the heavy lifting.
