Libraries

How to use LeoLM/leo-mistral-hessianai-7b with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="LeoLM/leo-mistral-hessianai-7b")

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("LeoLM/leo-mistral-hessianai-7b")
model = AutoModelForCausalLM.from_pretrained("LeoLM/leo-mistral-hessianai-7b", device_map="auto")

LAION LeoLM: Linguistically Enhanced Open Language Model

Meet LeoLM-Mistral, the first open and commercially available German Foundation Language Model built on Mistral 7b. Our models extend Llama-2's capabilities into German through continued pretraining on a large corpus of German-language and mostly locality specific text. Thanks to a compute grant at HessianAI's new supercomputer 42, we release three foundation models trained with 8k context length. LeoLM/leo-mistral-hessianai-7b under Apache 2.0 and LeoLM/leo-hessianai-7b and LeoLM/leo-hessianai-13b under the Llama-2 community license (70b also coming soon! 👀). With this release, we hope to bring a new wave of opportunities to German open-source and commercial LLM research and accelerate adoption. Read our blog post or our paper (preprint coming soon) for more details!

A project by Björn Plüster and Christoph Schuhmann in collaboration with LAION and HessianAI.

Model Details

Finetuned from: mistralai/Mistral-7B-v0.1
Model type: Causal decoder-only transformer language model
Language: English and German
License: Apache 2.0

Use in 🤗Transformers

First install direct dependencies:

pip install transformers torch accelerate

If you want faster inference using flash-attention2, you need to install these dependencies:

pip install packaging ninja
pip install flash-attn

Then load the model in transformers:

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained(
    model="LeoLM/leo-mistral-hessianai-7b",
    device_map="auto",
    torch_dtype=torch.bfloat16,
    use_flash_attn_2=True # optional
)
