onekq-ai/OneSQL-v0.1-Qwen-7B

Introduction

This model specializes on the Text-to-SQL task. It is finetuned from the quantized version of Qwen2.5-Coder-7B-Instruct. Its sibling 32B model has an EX score of 63.33 and R-VES score of 60.02 on the BIRD leaderboard.

Quick start

To use this model, craft your prompt to start with your database schema in the form of CREATE TABLE, followed by your natural language query preceded by --. Make sure your prompt ends with SELECT in order for the model to finish the query for you.
