Pneuma: Leveraging LLMs for Tabular Data Representation and Retrieval in an End-to-End System
Summary: Pneuma is an end-to-end RAG system using LLMs to represent and retrieve tabular data, preserving schema and row context for accurate discovery. Evaluated on six real-world datasets, it outperforms full-text search and state-of-the-art RAG in accuracy and efficiency. (summarized by gpt-5-nano on Feb 09 2026)
