| **Architecture** | Zen4 Frontier |
| **Context** | 262K tokens |
| **License** | APACHE-2.0 |
| **Family** | Zen4 |
| **Tier** | Small |
| **Creator** | Zen LM / Hanzo AI |
## Usage
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("zenlm/zen4-mini", torch_dtype="auto")
tokenizer = AutoTokenizer.from_pretrained("zenlm/zen4-mini")
messages = [{"role": "user", "content": "Hello, who are you?"}]
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)
print(tokenizer.decode(outputs[0][inputs.input_ids.shape[-1]:], skip_special_tokens=True))
```
