LLM evaluation harness updated with production data and adversarial testing

A new approach to evaluating Large Language Models (LLMs) has been proposed to address the issue of static evaluation harnesses failing to detect model regressions. This method involves refreshing evaluation datasets weekly with real production traces, stratified by intent cluster to ensure representative sampling. Additionally, a permanent adversarial set, curated from actual customer support tickets indicating model failures, is weighted heavily in the evaluation process to prioritize real-world performance.
