## 🚀 Usage

### Python (Transformers)

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

model_name = "LeeChanRX/LeeChan-3B-Instruct"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    device_map="auto",
    torch_dtype="auto"
)

messages = [
    {
        "role": "system",
        "content": "You are LeeChan-3B-Instruct, developed by LeeChanRX Studio."
    },
    {
        "role": "user",
        "content": "Hello! Introduce yourself."
    }
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

inputs = tokenizer(text, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.7,
    top_p=0.9
)

response = tokenizer.decode(
    outputs[0][inputs.input_ids.shape[-1]:],
    skip_special_tokens=True
)

print(response)
```
