# LLaMA-MoE-v1-3.5B (4/16)
[[💻 Code]](https://github.com/pjlab-sys4nlp/llama-moe) | [[📜 Technical Report]]()
👋 Very nice to meet you here~
❤️ This repo contains the model `LLaMA-MoE-v1-3.5B (4/16)`, which activates 4 out of 16 experts (3.5B parameters).
This model is NOT fine-tuned by instruction pairs, so it may not be good enough to act like a chatbot.
📢 LLaMA-MoE is a series of Mixture-of-Expert (MoE) models based on [LLaMA-2](https://huggingface.co/meta-llama/Llama-2-7b-hf).
You can find the code for training this model at [this repo](https://github.com/pjlab-sys4nlp/llama-moe).
💎 This series of models are obtained by partitioning original LLaMA FFNs into experts and further continual pre-training.
The total model size is only 6.7B parameters, which is very convenient for deployment and research usage.
More details could be found at [our technical report](https://arxiv.org/).
## 🚀 QuickStart
```python
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
model_dir = "llama-moe/LLaMA-MoE-v1-3_5B-4_16"
tokenizer = AutoTokenizer.from_pretrained(model_dir, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_dir, torch_dtype=torch.bfloat16, trust_remote_code=True)
model.eval()
model.to("cuda:0")
input_text = "Suzhou is famous of"
inputs = tokenizer(input_text, return_tensors="pt")
inputs = inputs.to("cuda:0")
pred = model.generate(**inputs, max_length=50, temperature=0.0)
print(tokenizer.decode(pred.cpu()[0], skip_special_tokens=True))
# Suzhou is famous of its beautiful gardens. The most famous one is the Humble Administrator's Garden. It is a classical Chinese garden with a history of more than 600 years. The garden is divided into three
