# Model Card: UAB-NLP/ProjGen_Finetuned_llama

A **LLaMA-3.2** based instruction-tuned model fine-tuned with **Unsloth + QLoRA** using 🤗 **Transformers**.  
This model is part of the **ProjGen project**, aimed at enhancing developer productivity through automated project generation and structured code scaffolding.

---

## Model Details

### Model Description
- **Base model:** `meta-llama/Llama-3.2-<SIZE>-Instruct` <!-- replace SIZE with e.g. 8B/70B -->
- **Finetuning method:** Unsloth + QLoRA (LoRA adapters)
- **Precision (train):** 4-bit NF4 quantization (bitsandbytes) + bf16 compute
- **Context length:** 4096
- **Task(s):** Instruction following & project/code generation
- **License:** Inherits from Meta’s LLaMA-3.2 license
- **Developed by:** UAB-NLP Group (Sai Praneeth Kumar, University of Alabama at Birmingham)
- **Finetuned from:** `meta-llama/Llama-3.2-<SIZE>-Instruct`
- **Shared by:** [UAB-NLP](https://huggingface.co/UAB-NLP)

### Model Sources
- **Repository:** [UAB-NLP/ProjGen_Finetuned_llama](https://huggingface.co/UAB-NLP/ProjGen_Finetuned_llama)
- **Project Paper:** ProjGen – Enhanced Developer Productivity for Flask Project Generation with a RAG-Enhanced Fine-Tuned Local LLM

---

## Intended Uses & Limitations

### Direct Use
- Generating Flask/Django/Streamlit project structures automatically.
- Instruction-following tasks related to software engineering and code generation.

### Downstream Use
- Further fine-tuning on domain-specific datasets (e.g., medical imaging, finance, etc.).
- Integration into developer assistants and productivity tools.

### Out-of-Scope / Limitations
- Not suitable for medical, legal, or financial decision-making without human review.
- May hallucinate or produce insecure/inefficient code if not monitored.

---

## Bias, Risks, and Limitations
The model inherits risks from the base **LLaMA-3.2** model:
- Possible hallucinations and factual inaccuracies.
- Dataset/domain biases reflected in responses.
- Outputs should be validated before production deployment.

**Recommendation:** Always pair outputs with testing, validation, and human oversight.

## Getting Started

### Inference (PEFT adapter form)
```python
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig

model_id = "UAB-NLP/ProjGen_Finetuned_llama"

tok = AutoTokenizer.from_pretrained(model_id)

bnb = BitsAndBytesConfig(load_in_4bit=True, bnb_4bit_quant_type="nf4", bnb_4bit_use_double_quant=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    quantization_config=bnb,
    device_map="auto",
    torch_dtype="auto"
)

prompt = "Generate a Flask project with login, dashboard, and reports."
inputs = tok(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512)
print(tok.decode(outputs[0], skip_special_tokens=True))
```
