## Introduction

We are excited to release the **Agentar-Scale-SQL-Generation-32B**, the core **Reasoning SQL Generator** used in our SOTA framework, **Agentar-Scale-SQL**. Our framework achieved **81.67% execution accuracy** on the challenging BIRD benchmark, ranking first on the official leaderboard.

This model is a key component of our "Orchestrated Test-Time Scaling" strategy and has several key features:

  - **Base Model:** It is fine-tuned from `Omni-SQL-32B`.
  - **RL-Enhanced Reasoning:** The model was further trained using an execution-grounded **Reinforcement Learning** framework (GRPO) to enhance its intrinsic reasoning capabilities.
  - **Deep Reasoning:** It is engineered to conduct deep, step-by-step reasoning and construct complex, high-accuracy SQL queries.

This model is one of the two main generators in the `Agentar-Scale-SQL` framework's "Diverse Synthesis" step, working in parallel with an ICL generator to produce a robust pool of SQL candidates.

## Prompt Template

````python
PROMPT_TEMPLATE = """Task Overview:
You are a data science expert. Below, you are provided with a database schema and a natural language question. Your task is to understand the schema and generate a valid SQL query to answer the question.

Database Engine:
{{ dialect }}

Database Schema:
{{ db_schemas }}
This schema describes the database's structure, including tables, columns, primary keys, foreign keys, and any relevant relationships or constraints.
{% if matched_contents %}
Matched contents:
{{ matched_contents }}
Matched contents presents values related to the question, together with their source table and column, for your reference in SQL generation.
{% endif %}
Question:
{%- if hint %}
{{ hint }}
{{ question }}
{%- else %}
{{ question }}
{%- endif %}

Instructions:
- If Matched contents is provided, you can use it as reference when generating the SQL query.
- Make sure you only output the information that is asked in the question. If the question asks for a specific column, make sure to only include that column in the SELECT clause, nothing more.
- The generated query should return all of the information asked in the question without any missing or extra information.
- Before generating the final SQL query, please think through the steps of how to write the query.

Output Format:
In your answer, please enclose the generated SQL query in a code block:
```sql
-- Your SQL query
```

Take a deep breath and think step by step to find the correct SQL query.
