Unveiling Challenges for LLMs in Enterprise Data Engineering

Summary: Identifies enterprise-specific obstacles for LLM-driven tabular data engineering—large tables, more complex tasks, and dependence on internal background knowledge. Systematic evaluation shows substantial accuracy degradation and practical limits of current LLMs in real-world enterprise settings. (summarized by gpt-5-mini on Mar 13 2026)
