| ## Overview |
| Arctic-Text2SQL-R1-7B is a 7-billion-parameter Text-to-SQL model fine-tuned using Group Relative Policy Optimization (GRPO) with a simple execution-based reward signal. It converts natural language questions into executable SQL queries. |

|
|
| ## Key Features |
|
|
| - **Lightweight RL formulation**: Uses only execution correctness and syntax validity as rewards. |
| - **State-of-the-art performance**: Achieves 68.9% execution accuracy on BIRD-dev and 68.5% on BIRD-test, with an average of 57.2% across six benchmarks (BIRD, Spider, Spider2.0, Spider-DK, EHRSQL, ScienceBenchmark) |
| - **Efficiency**: Outperforms many 70B+ models with only 7B parameters. |
|
|
| ## Intended Use |
|
|
| This model is designed for: |
|
|
| - Interactive natural language interfaces to relational databases. |
| - Data analytics tools enabling non-technical users to query databases. |
|
|
| ### Not intended for: |
| - Generation of non-SQL text or free-form natural language tasks. |
| - Production systems without validation, especially in safety-critical domains. |
|
|
| | Benchmark | Dev/Test Accuracy | |
| | ---------------- | ----------------- | |
| | BIRD-dev | 68.9% | |
| | BIRD-test | 68.5% | |
| | Spider-test | 88.8% | |
| | Spider2.0-DK | 15.6% | |
| | EHRSQL | 36.7% | |
| | ScienceBenchmark | 51.8% | |
| | **Average** | **57.2%** | |
|
|
|
|
| ## Ethical Considerations |
| - Avoid using for private or sensitive data without proper oversight. |
| - Validate generated SQL to prevent data leakage or unauthorized access. |
