About MindSQL

MindSQL is a Python RAG (Retrieval-Augmented Generation) Library that simplifies database interactions through natural language queries. It seamlessly integrates with popular relational databases like PostgreSQL, MySQL, SQLite, as well as cloud data warehouses such as Snowflake and BigQuery. The library leverages large language models (LLMs) including GPT-4, Llama 2, and Google Gemini, and enhances query accuracy with context-aware vector stores like ChromaDB and Faiss. Designed for self-hosting and extensibility, MindSQL provides a simple API for indexing database schemas, handling question-SQL pairs, and executing queries with optional visualization. It is installable via pip and requires Python 3.10 or higher.
