GRID: Grammar-Railed Decoding for Enterprise SQL Generation

arXiv cs.CL · 18 hours ago

Researchers developed GRID, a grammar-constrained decoding engine that ensures SQL generated by large language models is syntactically valid, respects access control policies, and provides compliance guarantees for enterprise use. The system achieves median per-token masking in 3.6-6.7 microseconds and improves execution accuracy by 13 points on Spider benchmarks at 0.5B model scale. This approach enables reliable SQL generation with enforceable security constraints and auditable decision records.
