Tailored to your business
Go beyond generic models. Defog uses AI that is customized for your database schema and aligned to your business logic. Deploy fine-tuned models, monitor their performance and stay aligned with human feedback.
Keep your data private
Defog only uses metadata to fine-tune LLMs for you – it's never given access to your actual database. You can use our cloud offering or deploy models on-prem.
Powered by SQLCoder
Defog is powered by SQLCoder – the best performing open-source model for text-to-SQL generation.

State-of-the-art model
SQLCoder-34B outperforms OpenAI’s gpt-4 and gpt-4-turbo on text to SQL generation, and significantly outperforms all major open-source models for out-of-training set SQL schemas in Postgres. When fine-tuned on individual database schemas, SQLCoder-34B has 99+% accuracy for text to SQL conversions.

Our evaluation framework
SQL-Eval is our open source framework to evaluate the correctness of LLM-generated SQL. Our goal is to produce a reproducible framework that measures both the complexity and semantic diversity of queries.







Supported databases
SQLCoder is compatible with all major SQL databases and data warehouses.
