Researchers have developed a new method for using large language models (LLMs) to assist in evaluating AI systems, moving beyond simple substitution of human reviewers. This approach frames LLM evaluations as an augmentation to human assessment, employing a two-stage sampling design. The proposed methodology utilizes a doubly robust estimator from missing data literature to account for LLM evaluations on all data points and human ratings on a subset, aiming to determine optimal sample sizes for both human and LLM reviews to achieve desired statistical power.
