# ARWKV-7B-GATE-MLP (Preview 0.1)

<img src="./figures/architecture.png" alt="ARWKV Hybrid Architecture" width="30%">

*Preview version with RWKV-7 time mixing and Transformer MLP*

## 📌 Overview

**ALL YOU NEED IS RWKV**

This is an **early preview** of our 7B parameter hybrid RNN-Transformer model, trained on 2k context length through 3-stage knowledge distillation from Qwen2.5-7B-Instruct. While being a foundational version, it demonstrates:

- ✅ RWKV-7's efficient recurrence mechanism
- ✅ No self-attention, fully O(n)
- ✅ Constant VRAM usage
- ✅ Single-GPU trainability

**Roadmap Notice**: We will soon open-source different enhanced versions with:
- 🚀 16k+ context capability
- 🧮 Math-specific improvements
- 📚 RL enhanced reasoning model

## How to use
```shell
pip3 install --upgrade rwkv-fla transformers
```

```python
from transformers import AutoModelForCausalLM, AutoTokenizer


model = AutoModelForCausalLM.from_pretrained(
    "RWKV-Red-Team/ARWKV-7B-Preview-0.1",
    device_map="auto",
    torch_dtype=torch.float16,
    trust_remote_code=True,
)
tokenizer = AutoTokenizer.from_pretrained(
    "RWKV-Red-Team/ARWKV-7B-Preview-0.1"
)
```

## 🔑 Key Features
