# Zen4 Max Pro
Pro variant of Zen4 Max with enhanced reasoning for enterprise agentic deployments.
## Overview
Built on **Zen MoDE (Mixture of Distilled Experts)** architecture with 1T+ MoE parameters and 256K 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/zen4-max-pro"
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))
```
