## Usage

```python
# Load the model
from safetensors.torch import load_file
from architecture.model import Qwen3Model  # Your custom model class

# Load config
import json
with open("config.json") as f:
    config = json.load(f)

# Initialize model
model = Qwen3Model(config)

# Load weights
state_dict = load_file("model.safetensors")
model.load_state_dict(state_dict)

# Load tokenizer
from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("kshitijthakkar/moe-415m-147m-16x2-12L-xlarge-450m-16exp")
```
