# DuckDB-NSQL-7B
|
|
|
|
## Model Description
|
|
|
|
NSQL is a family of autoregressive open-source large foundation models (FMs) designed specifically for SQL generation tasks.
|
|
|
|
In this repository we are introducing a new member of NSQL, DuckDB-NSQL. It's based on Meta's original [Llama-2 7B model](https://huggingface.co/meta-llama/Llama-2-7b) and further pre-trained on a dataset of general SQL queries and then fine-tuned on a dataset composed of DuckDB text-to-SQL pairs.
|
|
|
|
## Training Data
|
|
|
|
200k DuckDB text-to-SQL pairs, synthetically generated using [Mixtral-8x7B-Instruct-v0.1](https://huggingface.co/mistralai/Mixtral-8x7B-Instruct-v0.1), guided by the DuckDB v0.9.2 documentation. And text-to-SQL pairs from [NSText2SQL](https://huggingface.co/datasets/NumbersStation/NSText2SQL) that were transpiled to DuckDB SQL using [sqlglot](https://github.com/tobymao/sqlglot).
|
|
|
|
## Evaluation Data
|
|
|
|
We evaluate our models on a DuckDB-specific benchmark that contains 75 text-to-SQL pairs. The benchmark is available [here](https://github.com/NumbersStationAI/DuckDB-NSQL/).
|
|
|
|
## Training Procedure
|
|
|
|
DuckDB-NSQL was trained using cross-entropy loss to maximize the likelihood of sequential inputs. For finetuning on text-to-SQL pairs, we only compute the loss over the SQL portion of the pair. The model is trained using 80GB A100s, leveraging data and model parallelism. We fine-tuned for 10 epochs.
|
|
|
|
## Intended Use and Limitations
|
|
|
|
The model was designed for text-to-SQL generation tasks from given table schema and natural language prompts. The model works best with the prompt format defined below and outputs.
|
|
In contrast to existing text-to-SQL models, the SQL generation is not contrained to `SELECT` statements, but can generate any valid DuckDB SQL statement, including statements for official DuckDB extensions.

|
## How to Use
|
|
|
|
Example 1:
|
|
|
|
```python
|
|
import torch
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM
|
|
tokenizer = AutoTokenizer.from_pretrained("motherduckdb/DuckDB-NSQL-7B-v0.1")
|
|
model = AutoModelForCausalLM.from_pretrained("motherduckdb/DuckDB-NSQL-7B-v0.1", torch_dtype=torch.bfloat16)
|
|
|
|
text = """### Instruction:
|
|
Your task is to generate valid duckdb SQL to answer the following question.
|
|
|
|
### Input:
|
|
|
|

|
create a new table called tmp from test.csv

|
"""
|
|
|
|
input_ids = tokenizer(text, return_tensors="pt").input_ids
|
|
|
|
generated_ids = model.generate(input_ids, max_length=500)
|
|
print(tokenizer.decode(generated_ids[0], skip_special_tokens=True))
|
|
```
|
|
|
|
