# Model Information |
|
|
|
Azzurro is an updated version of [Mistral-7B-v0.2](https://huggingface.co/alpindale/Mistral-7B-v0.2-hf), specifically fine-tuned with SFT and LoRA adjustments. |
|
|
|
- It's trained on publicly available datasets, like [SQUAD-it](https://huggingface.co/datasets/squad_it), and datasets we've created in-house. |
|
- it's designed to understand and maintain context, making it ideal for Retrieval Augmented Generation (RAG) tasks and applications requiring contextual awareness. |
|
|
|
# Evaluation |
|
|
|
We evaluated the model using the same test sets as used for the [Open Ita LLM Leaderboard](https://huggingface.co/spaces/FinancialSupport/open_ita_llm_leaderboard) |

## Usage |
|
|
|
Be sure to install these dependencies before running the program |
|
|
|
```python |
|
!pip install transformers torch sentencepiece |
|
``` |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
device = "cpu" # if you want to use the gpu make sure to have cuda toolkit installed and change this to "cuda" |
|
|
|
model = AutoModelForCausalLM.from_pretrained("MoxoffSpA/Azzurro") |
|
tokenizer = AutoTokenizer.from_pretrained("MoxoffSpA/Azzurro") |
|
|
|
question = """Quanto è alta la torre di Pisa?""" |
|
context = """ |
|
La Torre di Pisa è un campanile del XII secolo, famoso per la sua inclinazione. Alta circa 56 metri. |
|
""" |
|
|
|
prompt = f"Domanda: {question}, contesto: {context}" |
|
|
|
messages = [ |
|
{"role": "user", "content": prompt} |
|
] |
|
|
|
encodeds = tokenizer.apply_chat_template(messages, return_tensors="pt") |
|
|
|
model_inputs = encodeds.to(device) |
|
model.to(device) |
|
|
|
generated_ids = model.generate( |
|
model_inputs, # The input to the model |
|
max_new_tokens=128, # Limiting the maximum number of new tokens generated |
|
do_sample=True, # Enabling sampling to introduce randomness in the generation |
|
temperature=0.1, # Setting temperature to control the randomness, lower values make it more deterministic |
|
top_p=0.95, # Using nucleus sampling with top-p filtering for more coherent generation |
|
eos_token_id=tokenizer.eos_token_id # Specifying the token that indicates the end of a sequence |
|
) |
|
|
|
decoded_output = tokenizer.decode(generated_ids[0], skip_special_tokens=True) |
|
trimmed_output = decoded_output.strip() |
|
print(trimmed_output) |
|
``` |
|
|
|
## Bias, Risks and Limitations |
|
|
|
Azzurro 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-v0.2), however it is likely to have included a mix of Web data and technical sources |
|
like books and code. |
