Lloro SQL, developed by Semantix Research Labs, is a language Model that was trained to effectively transform Portuguese queries into SQL Code. It is a fine-tuned version of meta-llama/Meta-Llama-3-8B-Instruct,  that was trained on Bird and Spider public datasets.  The fine-tuning process was performed using the QLORA metodology on a GPU A100 with 40 GB of RAM.

 

**Model description**


Model type: A 7B parameter  fine-tuned on GretelAI public datasets.

Language(s) (NLP): Primarily Portuguese, but the model is capable to understand English as well

Finetuned from model: meta-llama/Meta-Llama-3-8B-Instruct

 

**What is Lloro's intended use(s)?**


Lloro is built for Text2SQL in Portuguese contexts .

Input : Text

Output : Text (Code)


**Usage**


Using an OpenAI compatible inference server (like [vLLM](https://docs.vllm.ai/en/latest/index.html))

```python
from openai import OpenAI
client = OpenAI(
    api_key="EMPTY",
    base_url="http://localhost:8000/v1",
)
def generate_responses(instruction, client=client):
    
    chat_response = client.chat.completions.create(
    model=<model>,
    messages=[
        {"role": "system", "content": "Você escreve a instrução SQL que responde às perguntas feitas. Você NÃO FORNECE NENHUM COMENTÁRIO OU EXPLICAÇÃO sobre o que o código faz, apenas a instrução SQL terminando em ponto e vírgula. Você utiliza todos os comandos disponíveis na especificação SQL, como: [SELECT, WHERE, ORDER, LIMIT, CAST, AS, JOIN]."},
        {"role": "user", "content": instruction},
    ]
)
    
    return chat_response.choices[0].message.content

output = generate_responses(user_prompt)

```
