Researchers have developed a new framework called GradeSQL to improve the reliability of large language models (LLMs) in Text-to-SQL tasks. This framework utilizes Outcome Reward Models (ORMs) as learned semantic scoring functions for test-time verification, a method previously underexplored for structured query generation. GradeSQL trains ORMs using automated candidate generation and execution-based labeling, eliminating the need for manual annotation. When integrated into a verification-driven pipeline, ORM-based selection consistently outperforms traditional methods like Best-of-N sampling and Majority Voting on benchmarks such as BIRD and Spider, showing significant accuracy gains, particularly on complex queries.
