Last Update: 20/02/2024

Zefiro base is a continual pretrained model for the Italian language based on Mistral-7b trained on a subset of the Italian subdataset of Oscar and wikipedia dataset.

Model Details

Zefiro base is a continual pre-trained language model started from mistralai/Mistral-7B-v0.1 model to the italian language.

Model description




It has been trained on a GPUs cluster of 4 H100s from runpod

Intended uses & limitations

Here's how you can run the model using Transformers from 🤗 :

# Install transformers from source - only needed for versions <= v4.34
# pip install git+https://github.com/huggingface/transformers.git
# pip install accelerate
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "mii-community/zefiro-7b-base-ITA"
model = AutoModelForCausalLM.from_pretrained(model_id)
tokenizer = AutoTokenizer.from_pretrained(model_id, padding_side="left")

sys_prompt = "Sei un assistente disponibile, rispettoso e onesto. " \
         "Rispondi sempre nel modo piu' utile possibile, pur essendo sicuro. " \
         "Le risposte non devono includere contenuti dannosi, non etici, razzisti, sessisti, tossici, pericolosi o illegali. " \
         "Assicurati che le tue risposte siano socialmente imparziali e positive. " \
         "Se una domanda non ha senso o non e' coerente con i fatti, spiegane il motivo invece di rispondere in modo non corretto. " \
         "Se non conosci la risposta a una domanda, non condividere informazioni false."

messages = [{ 'content' : sys_prompt, 'role' : 'assistant'}, 
            {'content' : 'Crea una lista su cosa mangiare a pranzo ogni giorno della settimana a pranzo e cena', 'role' : 'user'}]

def generate_text(sys_prompt, user_prompt):
    messages = [{ 'content' : sys_prompt, 'role' : 'assistant'}, 
            {'content' : user_prompt, 'role' : 'user'}]
    prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
    model_inputs = tokenizer([prompt], return_tensors="pt").to("cuda")
    generated_ids = model.generate(**model_inputs, max_new_tokens=1024)
    return tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

generate_text(sys_prompt, 'cosa ne pensi della politica italiana?')

Bias, Risks, and Limitations

Zefiro-7b-base-ITA has not been aligned to human preferences for safety within the RLHF phase or deployed with in-the-loop filtering of responses like ChatGPT, so the model can produce problematic outputs (especially when prompted to do so). It is also unknown what the size and composition of the corpus was used to train the base model (mistralai/Mistral-7B-v0.1), however it is likely to have included a mix of Web data and technical sources like books and code. See the Falcon 180B model card for an example of this.

Training Data

We used a subset of the italian version of Oscar and Wikipedia a as training data.


Zefiro-7b-beta-ITA-v0.1 is a continula pre-trained version of mistral-7b for the italian language.
