NSQL is an open-source family of SQL-specialized language models from NumbersStation, fine-tuned from foundation models including Llama and CodeLlama. The NSQL-Llama-2-7B model provides a lightweight option for teams with limited GPU resources while maintaining competitive accuracy on standard benchmarks. Training combines the Spider dataset with proprietary enterprise SQL examples. The models support multiple SQL dialects and handle complex queries including nested subqueries, window functions, and CTEs. Available through Hugging Face for self-hosted deployment. NumbersStation also offers an enterprise platform with additional features including semantic layer integration and query optimization.
