Researchers have introduced CARTBench, a new evaluation framework designed to assess the performance of large language models (LLMs) in providing shopping advice for complex and ambiguous requests, especially those involving timelines. The benchmark addresses data scarcity by curating real-world shopping needs across 17 retail domains and standardizes evaluation criteria using rubrics derived from ideal response principles. Initial evaluations of commercial models like GPT-6.1-Sol and Claude-Opus-5, alongside open-weight models, revealed a significant gap between models' core functionality and their ability to deliver high-quality, excellent purchase advice, particularly in handling evolving requirements and uncertainties.
