• Feb. 2025 🌟 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.
• Dec. 2024 🌟 We are excited to open source the XiYanSQL-QwenCoder-32B model: XiYanSQL-QwenCoder-32B achieves an EX score of 69.03% on the BIRD test set, setting a new SOTA under only a single fine-tuned model.

Introduction

We are excited to release the XiYanSQL-QwenCoder-2504 version, our latest SQL generation model. This version continues to optimize upon the previous version, delivering enhanced performance.

• Our model incorporates important explorations combining fine-tuning and GRPO training, leveraging the post-training strategies of GRPO without a thinking process, achieving both efficiency and accuracy in SQL generation.
• It demonstrates impressive performance and supports multiple dialects, ready to use out of the box.
• Improved generalization capabilities, excelling on different dialects and out-of-domain datasets.

In this evaluation, we have also added a real-world SQL benchmark (the DW test set), which serves as an important internal evaluation baseline. This test set includes thousands of complex queries from real scenarios in both PostgreSQL and MySQL dialects, effectively reflecting the model's performance across multiple dialects and out-of-domain data.

We are excited to open source the XiYanSQL-QwenCoder series model, dedicated to advancing the development of LLMs in the text-to-SQL domain. As of now, XiYanSQL-QwenCoder covers four mainstream model sizes: 3B, 7B, 14B, and 32B parameters, to meet the needs of different developers.

• The XiYanSQL-QwenCoder model demonstrates strong performance in SQL generation, with the XiYanSQL-QwenCoder-32B achieving a 69.03% EX score on the BIRD TEST set, setting a new SOTA with a single fine-tuned model. Other models in the series also maintain a leading position at their respective sizes.
• The XiYanSQL-QwenCoder model supports multiple SQL dialects, such as SQLite, PostgreSQL, and MySQL.
• The XiYanSQL-QwenCoder model can be used directly for text-to-SQL tasks or serve as a better starting point for fine-tuning SQL models.

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 as SQLite benchmarks in the Text-to-SQL domain, as well as DW benchmarks for PostgreSQL and MySQL dialects.

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.

In response to community demands, we have also included example code for inference using vLLM.

Prompt Template
