A capable large language model for natural language to SQL generation.


## Model Details
### Model Description
This is the model card of a 🤗 transformers model that has been pushed on the Hub. This model card has been automatically generated.

Developed by: eglym
Model type: [Text to SQL]
License: [CC-by-SA-4.0]
Finetuned from model: [CodeLlama-7B]

Use the code here to get started with the model.

Prompt
Please use the following prompt for optimal results. Please remember to use do_sample=False and num_beams=4 for optimal results.

### Task
Generate a SQL query to answer user_question.


### Answer
Given the database schema, here is the SQL query that realize user_question.

Evaluation
This model was evaluated on SQL-Eval, a PostgreSQL based evaluation framework developed by Defog for testing and alignment of model capabilities.

You can read more about the methodology behind SQLEval here.

Results
We classified each generated question into one of 6 categories. The table displays the percentage of questions answered correctly by each model, broken down by category.
