## Usage

### Using the LoRA Adapter

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

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen2.5-Coder-1.5B-Instruct",
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "cazim/homework-qwen-coder-deep-lora")

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-Coder-1.5B-Instruct")

# Generate code
system_prompt = "You are an expert Python programmer. Please read the problem carefully before writing any Python code."
problem = "Write a function to find the factorial of a number."

messages = [
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": problem},
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.1,
    top_p=0.95,
    do_sample=True,
)

generated_code = tokenizer.decode(outputs[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True)
print(generated_code)
```

### Using Merged Model

If this is a merged model, you can use it directly:

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained(
    "cazim/homework-qwen-coder-deep-lora",
    torch_dtype=torch.bfloat16,
    device_map="auto",
)
tokenizer = AutoTokenizer.from_pretrained("cazim/homework-qwen-coder-deep-lora")
```

## Evaluation Results

Evaluation results will be added after benchmark testing.

## Limitations

- This model is fine-tuned specifically for competitive programming problems
- Best used with the provided system prompt
- May not generalize well to other code generation tasks

## System Prompt

```
You are an expert Python programmer. Please read the problem carefully before writing any Python code.
```
