# 🐍 TinyLLaMA LoRA - Fine-tuned on Python Code

This is a **LoRA fine-tuned version** of [`TinyLlama/TinyLlama-1.1B-Chat-v1.0`](https://huggingface.co/TinyLlama/TinyLlama-1.1B-Chat-v1.0) using a subset of Python code from the `codeparrot` dataset. It is trained to generate Python functions and code snippets based on natural language or code-based prompts.

## 🔧 Training Details

- **Base model**: `TinyLlama/TinyLlama-1.1B-Chat-v1.0`
- **Adapter type**: LoRA (PEFT)
- **Dataset**: `codeparrot/codeparrot-clean-valid[:1000]`
- **Tokenized max length**: 512
- **Trained on**: Apple M3 Pro (MPS backend)
- **Epochs**: 1
- **Batch size**: 1 (with gradient accumulation)

## 💡 Example Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

base_model = "TinyLlama/TinyLlama-1.1B-Chat-v1.0"
adapter_model = "your-username/tinyllama-python-lora"

tokenizer = AutoTokenizer.from_pretrained(base_model)
model = AutoModelForCausalLM.from_pretrained(base_model)
model = PeftModel.from_pretrained(model, adapter_model)

prompt = "<|python|>\ndef fibonacci(n):"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

## 🧠 Intended Use
Code completion for Python

Teaching LLMs Python function structure

Experimentation with LoRA on small code datasets

##⚠️ Limitations
Trained on a small subset of data (1,000 samples)

May hallucinate or generate syntactically incorrect code

Not suitable for production use without further fine-tuning and evaluation
