Logical and Physical Optimizations for SQL Query Execution over Large Language Models

Summary: Galois sits between SQL and LLMs, using LLMs as a storage layer with LLM-aware physical operators. LLM-focused optimization with dynamic metadata beats conventional plans, delivering up to 144% quality gains vs NL questions and 29% vs SQL. (summarized by gpt-5-nano on Feb 09 2026)
