Vigogne-2-70B-Chat: A Llama-2-based French Chat LLM

Vigogne-2-70B-Chat is a French chat LLM, based on Llama-2-70B, optimized to generate helpful and coherent responses in conversations with users.

Check out our release blog and GitHub repository for more information.

Usage and License Notices: Vigogne-2-70B-Chat follows Llama-2's usage policy. A significant portion of the training data is distilled from GPT-3.5-Turbo and GPT-4, kindly use it cautiously to avoid any violations of OpenAI's terms of use.

Prompt Template

We used a prompt template adapted from the chat format of Llama-2.

You can apply this formatting using the chat template through the apply_chat_template() method.

from transformers import AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("bofenghuang/vigogne-2-70b-chat")

conversation = [
    {"role": "user", "content": "Bonjour ! Comment ça va aujourd'hui ?"},
    {"role": "assistant", "content": "Bonjour ! Je suis une IA, donc je n'ai pas de sentiments, mais je suis prêt à vous aider. Comment puis-je vous assister aujourd'hui ?"},
    {"role": "user", "content": "Quelle est la hauteur de la Tour Eiffel ?"},
    {"role": "assistant", "content": "La Tour Eiffel mesure environ 330 mètres de hauteur."},
    {"role": "user", "content": "Comment monter en haut ?"},
]

print(tokenizer.apply_chat_template(conversation, tokenize=False, add_generation_prompt=True))

You will get

<s>[INST] <<SYS>>
Vous êtes Vigogne, un assistant IA créé par Zaion Lab. Vous suivez extrêmement bien les instructions. Aidez autant que vous le pouvez.
<</SYS>>

Bonjour ! Comment ça va aujourd'hui ? [/INST] Bonjour ! Je suis une IA, donc je n'ai pas de sentiments, mais je suis prêt à vous aider. Comment puis-je vous assister aujourd'hui ? </s>[INST] Quelle est la hauteur de la Tour Eiffel ? [/INST] La Tour Eiffel mesure environ 330 mètres de hauteur. </s>[INST] Comment monter en haut ?

Limitations

Vigogne is still under development, and there are many limitations that have to be addressed. Please note that it is possible that the model generates harmful or biased content, incorrect information or generally unhelpful answers.
