News

We are excited to open source the XiYanSQL-QwenCoder series model, dedicated to advancing the development of LLMs in the Text-to-SQL domain.

Building on our previous release of the powerful 32B model, this release introduces three model sizes: 3B, 7B, and 14B. As of now, XiYanSQL-QwenCoder covers a variety of mainstream model sizes to meet the needs of different developers.

Introduction

We open-source the first XiYanSQL-QwenCoder-32B model on January 22, 2025, and we look forward to contributing to the Text-to-SQL community. XiYanSQL-QwenCoder-32B, a SQL model fine-tuned on the Qwen2.5Coder-32B model, achieves an EX score of 69.03% on the BIRD test set, setting a new SOTA under only a single fine-tuned model.

Performance

The XiYanSQL-QwenCoder models, as multi-dialect SQL base models, demonstrating robust SQL generation capabilities. The following presents the evaluation results at the time of release. We conducted a comprehensive evaluation of the model's performance under two schema formats, M-Schema, and original DDL, using the BIRD and Spider benchmarks in the Text-to-SQL domain.

transformers >= 4.37.0

Quickstart

NOTE: XiYanSQL-QwenCoder models can be used directly for text-to-SQL tasks or serve as a better starting point for fine-tuning SQL models.

Here is a simple code snippet for quickly using XiYanSQL-QwenCoder model. We provide a Chinese version of the prompt, and you just need to replace the placeholders for "question," "db_schema," and "evidence" to get started. We recommend using our M-Schema format for the schema; other formats such as DDL are also acceptable, but they may affect performance. Currently, we mainly support mainstream dialects like SQLite, PostgreSQL, and MySQL.

nl2sqlite_template_cn = """你是一名{dialect}专家，现在需要阅读并理解下面的【数据库schema】描述，以及可能用到的【参考信息】，并运用{dialect}知识生成sql语句回答【用户问题】。
【用户问题】
{question}

【数据库schema】
{db_schema}
