Abstract
The 2024 NIST Generative AI (GenAI) Pilot Study focuses on evaluating text-to-text (T2T) generation and discrimination tasks to assess the capabilities and limitations of generative AI models. The study aims to measure the effectiveness of AI-generated text in mimicking human writing and the ability of AI-based discriminators to distinguish between human- and AI-generated content. A curated dataset of human-authored and machine-generated summaries served as the benchmark, with performance assessed using statistical and machine-learning-based metrics, including AUC (Area Under the Curve) and Brier scores. The presentation includes the evaluation submissions, data analyses, results, challenges, and future work.Citation
