# GeoSQL-14B

GeoSQL-14B is a 14B-parameter spatial text-to-SQL model fine-tuned from `Qwen/Qwen2.5-Coder-14B-Instruct`. It is designed to generate executable PostGIS SQL queries from a natural language question and a database schema.

## Model Details

| Item | Description                      |
| --- |----------------------------------|
| Model name | `GeoSQL-14B`                      |
| Base model | `Qwen/Qwen2.5-Coder-14B-Instruct` |
| Primary task | Natural language to spatial SQL  |
| Output format | A single SQL query               |

## Intended Use

GeoSQL-14B is intended for research and application development in spatial text-to-SQL. Given a database schema and a user question, the model generates SQL that uses PostGIS syntax, including spatial predicates, measurements, joins, aggregations, and coordinate transformations when needed.
