Copied to clipboard
| Challenge: | Large Language Models (LLMs) blur role boundaries by producing unrestricted responses. |
| Approach: | They propose to extend the Spider and BIRD text-to-SQL datasets with real-time PostgreSQl role-based policies at the table and column levels. |
| Outcome: | The proposed model improves refusal precision and lowers false permits. |
