🧐 About This Model

Model full name: Llama3.1-MagpieLM-4B-Chat-v0.1

This model is an aligned version of Llama-3.1-Minitron-4B-Width, which achieves state-of-the-art performance among open-aligned SLMs. It even outperforms larger open-weight models including Llama-3-8B-Instruct, Llama-3.1-8B-Instruct and Qwen-2-7B-Instruct.

We apply the following standard alignment pipeline with two carefully crafted synthetic datasets. Feel free to use these datasets and reproduce our model, or make your own friendly chatbots :)

We first perform SFT using Magpie-Align/MagpieLM-SFT-Data-v0.1.

• SFT Model Checkpoint: Magpie-Align/MagpieLM-4B-SFT-v0.1

We then perform DPO on the Magpie-Align/MagpieLM-DPO-Data-v0.1 dataset.

👀 Other Information

License: Please follow NVIDIA Open Model License Agreement.

Conversation Template: Please use the Llama 3 chat template for the best performance.

Limitations: This model primarily understands and generates content in English. Its outputs may contain factual errors, logical inconsistencies, or reflect biases present in the training data. While the model aims to improve instruction-following and helpfulness, it isn't specifically designed for complex reasoning tasks, potentially leading to suboptimal performance in these areas. Additionally, the model may produce unsafe or inappropriate content, as no specific safety training were implemented during the alignment process.

🧐 How to use it?

Please update transformers to the latest version by pip install git+https://github.com/huggingface/transformers.

You can then run conversational inference using the Transformers pipeline abstraction or by leveraging the Auto classes with the generate() function.

import transformers
import torch

model_id = "MagpieLM-4B-Chat-v0.1"

pipeline = transformers.pipeline(
    "text-generation",
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
    device_map="auto",
)

messages = [
    {"role": "system", "content": "You are Magpie, a friendly AI assistant."},
    {"role": "user", "content": "Who are you?"},
]

outputs = pipeline(
    messages,
    max_new_tokens=256,
)
print(outputs[0]["generated_text"][-1])

Alignment Pipeline

The detailed alignment pipeline is as follows.

Stage 1: Supervised Fine-tuning

We use Axolotl for SFT. Please refer to the model card of SFT checkpoint and below for detailed configurations.
