APEX-SQL: Talking to the data via Agentic Exploration for Text-to-SQL
Researchers introduce APEX-SQL, an agentic framework that improves Text-to-SQL systems by using hypothesis-verification loops and real data exploration instead of static schema representations. The system achieves 70.65% execution accuracy on BIRD and 51.01% on Spider 2.0-Snow benchmarks, demonstrating significant performance gains for enterprise database query generation.
