Cents: A Flexible and Cost-Effective Framework for LLM-Based Table Understanding

Summary: Cents unifies LLM-based table-understanding tasks in a flexible framework, rather than task-specific systems. Its tabular-input compression reduces token cost while improving accuracy, outperforming prior LLM baselines across tasks at equal or lower cost. (summarized by gpt-5.6-luna on Jul 24 2026)
