Introducing LLM as a Judge: Scaling search relevance evaluation with AI

OpenSearch 3.5 introduces "LLM as a Judge," a new feature that leverages large language models to automatically and at scale evaluate search result relevance. This approach provides a cost-effective, consistent, and 24/7 alternative to traditional human evaluation methods, which are often expensive and difficult to scale. By integrating with the Search Relevance Workbench, it allows teams to use custom prompts to perform complex, multi-dimensional assessments tailored to their specific domains.
