> **Superseded — archived checkpoint.** This is the v1.0.1 *family overview*; its weights are a Qwen3-8B fine-tune. See the current lineup at [huggingface.co/zenlm](https://huggingface.co/zenlm). Weights are kept available for reproducibility.

# Zen AI Model Family (v1.0.1, archived)

## Base model & attribution

Fine-tuned from [**Qwen/Qwen3-8B**](https://huggingface.co/Qwen/Qwen3-8B) (Apache-2.0) with Hanzo identity + agentic-data training + abliteration.

Zen fine-tunes the best open-weight model of each era. Across this family that is the **Qwen3** line from Alibaba Cloud — base, VL, Omni, Embedding, Reranker, TTS, ASR, Guard, Coder — with media models on permissive bases (Wan, FLUX, TRELLIS, YuE). Hanzo adds only identity training, agentic-data fine-tuning, and abliteration. There is no from-scratch Zen model.

## Quick start

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("zenlm/zen-family")
tokenizer = AutoTokenizer.from_pretrained("zenlm/zen-family")

messages = [{"role": "user", "content": "Hi, what can you help me with?"}]
inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt")
outputs = model.generate(inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0][inputs.shape[-1]:], skip_special_tokens=True))
```
