# LAION LeoLM: **L**inguistically **E**nhanced **O**pen **L**anguage **M**odel
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`](https://huggingface.co./LeoLM/leo-mistral-hessianai-7b) under Apache 2.0 and
[`LeoLM/leo-hessianai-7b`](https://huggingface.co./LeoLM/leo-hessianai-7b) and [`LeoLM/leo-hessianai-13b`](https://huggingface.co./LeoLM/leo-hessianai-13b) under the [Llama-2 community license](https://huggingface.co./meta-llama/Llama-2-70b/raw/main/LICENSE.txt) (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](https://laion.ai/blog/leo-lm/) or our paper (preprint coming soon) for more details!
*A project by Björn Plüster and Christoph Schuhmann in collaboration with LAION and HessianAI.*

## 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:
```bash
pip install packaging ninja
pip install flash-attn
```
Then load the model in transformers:
```python
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
)
```
## Training parameters
Note that for Mistral training, we changed learning rate to `1e-5` going down to `1e-6`. We also used Zero stage 3 and bfloat16 dtype.
