Occiglot-7B-DE-EN-Instruct

A polyglot language model for the Occident.

Occiglot-7B-DE-EN-Instruct is a the instruct version of occiglot-7b-eu5, a generative language model with 7B parameters supporting German and English and trained by the Occiglot Research Collective. It was trained on 180M tokens of additional multilingual and code instructions. Note that the model was not safety aligned and might generate problematic outputs.

This is the first release of an ongoing open research project for multilingual language models. If you want to train a model for your own language or are working on evaluations, please contact us or join our Discord server. We are open for collaborations!

*Special thanks go to Disco Research, Jan Philipp Harries, and Björn Plüster for sharing the German dataset with us*

How to use

The model was trained using the chatml instruction template. You can use the transformers chat template feature for interaction. Since the generation relies on some randomness, we set a seed for reproducibility:

>>> from transformers import AutoTokenizer, MistralForCausalLM, set_seed
>>> tokenizer = AutoTokenizer.from_pretrained("occiglot/occiglot-7b-de-en-instruct")
>>> model = MistralForCausalLM.from_pretrained('occiglot/occiglot-7b-de-en-instruct')  # You may want to use bfloat16 and/or move to GPU here
>>> set_seed(42)
>>> messages = [
>>>    {"role": "system", 'content': 'You are a helpful assistant. Please give short and concise answers.'},
>>>    {"role": "user", "content": "Wer ist der deutsche Bundeskanzler?"},
>>> ]
>>> tokenized_chat = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_dict=False, return_tensors='pt',)
>>> set_seed(42)
>>> outputs = model.generate(tokenized_chat.to('cuda'), max_new_tokens=200,)
>>> tokenizer.decode(out[0][len(tokenized_chat[0]):])
'Der deutsche Bundeskanzler ist Olaf Scholz.'

Dataset

The training data was split evenly between German and English based on the total number of tokens. We would like to thank Disco Research, Jan Philipp Harries, and Björn Plüster for making their dataset available to us.

English and Code

Open-Hermes-2B

German

DiscoLM German Dataset includes the publicly available germanrag dataset
OASST-2 (German subset)
Aya-Dataset (German subset)

Training settings

Full instruction fine-tuning on 8xH100.
0.6 - 4 training epochs (depending on dataset sampling).
Framework: axolotl
Precision: bf16

Tokenizer

Tokenizer is unchanged from Mistral-7B-v0.1.

Evaluation

Preliminary evaluation results can be found below. Please note that the non-English results are based on partially machine-translated datasets and English prompts (Belebele and Okapi framework) and thus should be interpreted with caution, e.g., biased towards English model performance. Currently, we are working on more suitable benchmarks for Spanish, French, German, and Italian.
