LLaMAntino-2-chat-7b is a Large Language Model (LLM) that is an italian-adapted LLaMA 2 chat. This model aims to provide Italian NLP researchers with a base model for italian dialogue use cases.

The model was trained using QLora and using as training data clean_mc4_it medium. If you are interested in more details regarding the training procedure, you can find the code we used at the following link:

How to Get Started with the Model

Below you can find an example of model usage:

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "swap-uniba/LLaMAntino-2-chat-7b-hf-ITA"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

prompt = "Scrivi qui un possibile prompt"

input_ids = tokenizer(prompt, return_tensors="pt").input_ids
outputs = model.generate(input_ids=input_ids)

print(tokenizer.batch_decode(outputs.detach().cpu().numpy()[:, input_ids.shape[1]:], skip_special_tokens=True)[0])

If you are facing issues when loading the model, you can try to load it quantized:

model = AutoModelForCausalLM.from_pretrained(model_id, load_in_8bit=True)

Note: The model loading strategy above requires the bitsandbytes and accelerate libraries
