# Zen Nano 0.6b

Ultra-lightweight 0.6B language model optimized for edge and mobile deployment.

## Overview

Built on **Zen MoDE (Mixture of Distilled Experts)** architecture with 0.6B parameters and 32K context window.

Developed by [Hanzo AI](https://hanzo.ai) and the [Zoo Labs Foundation](https://zoo.ngo).

## Quick Start

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "zenlm/zen-nano-0.6b"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="auto", device_map="auto")

messages = [{"role": "user", "content": "Hello!"}]
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))
```

## API Access
