LLM reranker bug fixed, boosting text-to-SQL accuracy

By PulseAugur Editorial · [1 sources] ·

A developer discovered a bug in their LLM reranker for the schemagate text-to-SQL tool where the model was being called but not providing answers due to token limits, causing the system to silently fall back to a less effective mathematical ranking. The issue was fixed by increasing the `max_tokens` parameter and adding more robust testing to ensure the model actually responds. When the reranker functioned correctly, it significantly improved the accuracy of table selection for SQL generation on benchmarks like Spider and BIRD. AI

IMPACT Fixing this bug significantly improves the accuracy of text-to-SQL systems by ensuring LLM rerankers function correctly, leading to better table selection for complex queries.

    My LLM reranker did nothing, and every test passed

    <p>schemagate picks the few tables a text-to-SQL model should see out of hundreds. It ranks them with plain maths first (BM25, embeddings, name matching, fused with RRF). Then, if you give it an API key, a model can reorder the top 20. That second step is the reranker.</p> <p>I w…
