## 🚀 Usage

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

model_name = "teolm30/Fox-1.5-Nova"
bnb_config = BitsAndBytesConfig(load_in_4bit=True, bnb_4bit_quant_type="nf4")
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_name, quantization_config=bnb_config, device_map="auto")

prompt = "Write a Python LRU cache"
messages = [{"role": "user", "content": prompt}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=512, do_sample=True, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

## ⚠️ Limitations

- 4-bit model is 3.7GB
- No built-in tool-use (use OpenClaw agent loop)
