## TL;DR

Golden tests are fixed, source-controlled examples that an LLM system should answer or handle correctly. Evaluation datasets broaden that idea across tasks, metrics, and model behaviors.

## Core Explanation

For product teams, golden tests catch regressions in prompts, retrieval, tool use, safety policy, and model upgrades. Benchmark datasets provide broader comparability but may not match the product's real user intents. A practical evaluation program usually needs both: public benchmarks for broad signals and internal golden tests for business-critical workflows.
