Gemma SQL Copilot (LoRA)
This is a fine-tuned version of Google's Gemma 2B-IT model designed specifically for Text-to-SQL generation. It translates natural English instructions into properly formatted SQL queries.
The model was fine-tuned using Unsloth for efficient 4-bit quantization and LoRA (Low-Rank Adaptation), meaning it is highly memory efficient and can be run locally on consumer GPUs (like an RTX 3050 6GB) with minimal VRAM.
🛠️ Intended Use
- Task: Natural Language to SQL (Text-to-SQL)
- Use Case: Helping data analysts, developers, and business users query databases simply by asking questions in plain English.
- Environment: Designed for fast, low-memory inference using
unsloth.
✍️ Prompt Format
This model was trained on a specific prompt structure. To get the best results, you must wrap your question in the following format:
### Instruction:
Write a SQL query to find all users who signed up in 2023.
### Response:
<leave this blank for the model to generate the SQL>
💻 Example Usage
# pip install unsloth
from unsloth import FastLanguageModel
model, tokenizer = FastLanguageModel.from_pretrained(
model_name = "Noor201/gemma-sql-copilot-lora",
max_seq_length = 2048,
dtype = None,
load_in_4bit = True,
)
FastLanguageModel.for_inference(model)
prompt = """### Instruction:
Write a SQL query to find the names of all employees in the 'Sales' department who earn more than 50000.
### Response:
"""
inputs = tokenizer([prompt], return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=128)
print(tokenizer.batch_decode(outputs, skip_special_tokens=True)[0])
