PremiseSQL: Evaluating Premise Critique and Abstention in Text-to-SQL Systems

PremiseSQL introduces a benchmark of 1,800 flawed natural language to SQL (NL2SQL) queries, grouped into four categories of premise failures, alongside their original valid counterparts. The study evaluates large language models’ ability to critique flawed premises and abstain from generating misleading SQL, using an evaluation framework across three prompting settings. Results show that current models tend to trust premises and rarely critique them, while stronger critique-oriented prompting improves detection but also raises false invalid judgments and reduces SQL generation for valid queries.

Ask don't tell: Reducing sycophancy in large language models

arXiv:2602. 23971v4 Announce Type: replace-cross Abstract: Sycophancy, the tendency of large language models to favour user-affirming responses over critical engagement, has been identified as an alignment failure, particularly in high-stakes advisory and social contexts.
