## 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 d…
