# Qwen Commit LoRA - Conventional Commit Message Generator
Generates conventional commit messages from git diffs using a fine-tuned Qwen2.5-Coder-3B model with QLoRA adapters.
## Model Details
- **Base Model**: [Qwen/Qwen2.5-Coder-3B-Instruct](https://huggingface.co/Qwen/Qwen2.5-Coder-3B-Instruct)
- **Fine-tuning Method**: QLoRA (4-bit quantized, rank=8, alpha=16)
- **Training Data**: 210 real conventional commits from open-source repositories
- **Target Modules**: q_proj, k_proj, v_proj, o_proj
## Usage
```python
from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer
# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
"Qwen/Qwen2.5-Coder-3B-Instruct",
load_in_4bit=True,
device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-Coder-3B-Instruct")
# Load LoRA adapters
model = PeftModel.from_pretrained(base_model, "Pavloffm/qwen-commit-lora")
# Generate commit message
diff = """diff --git a/src/main.py b/src/main.py
index 1234567..abcdefg 100644
--- a/src/main.py
+++ b/src/main.py

+def new_feature():
+ pass
"""
messages = [{"role": "user", "content": f"Generate a conventional commit message for this diff:\n{diff}"}]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)
outputs = model.generate(inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
