# Model Card for Minerva-7B-instruct-v1.0

Minerva is the first family of **LLMs pretrained from scratch on Italian** developed by [Sapienza NLP](https://nlp.uniroma1.it)
in collaboration with [Future Artificial Intelligence Research (FAIR)](https://fondazione-fair.it/) and [CINECA](https://www.cineca.it/).
Notably, the Minerva models are truly-open (data and model) Italian-English LLMs, with approximately half of the pretraining data 
including Italian text.

* [Minerva LLMs - website](https://nlp.uniroma1.it/minerva/)

## Description

This is the model card for **Minerva-7B-instruct-v1.0**, a 7 billion parameter model trained on almost 2.5 trillion tokens (1.14 trillion in Italian, 
1.14 trillion in English and 200 billion in code).

This model is part of the Minerva LLM family:

* [Minerva-350M-base-v1.0](https://huggingface.co/sapienzanlp/Minerva-350M-base-v1.0)
* [Minerva-1B-base-v1.0](https://huggingface.co/sapienzanlp/Minerva-1B-base-v1.0)
* [Minerva-3B-base-v1.0](https://huggingface.co/sapienzanlp/Minerva-3B-base-v1.0)
* [Minerva-7B-base-v1.0](https://huggingface.co/sapienzanlp/Minerva-7B-base-v1.0)

## 🚨⚠️🚨 Bias, Risks, and Limitations 🚨⚠️🚨

*This section identifies foreseeable harms and misunderstandings.*

This is a chat foundation model, subject to model alignment and safety risk mitigation strategies. However, the model may still:

-   Overrepresent some viewpoints and underrepresent others
-   Contain stereotypes
-   Contain [personal information](#personal-data-and-information)
-   Generate:
    -   Racist and sexist content
    -   Hateful, abusive, or violent language
    -   Discriminatory or prejudicial language
    -   Content that may not be appropriate for all settings, including sexual content
-   Make errors, including producing incorrect information or historical facts as if it were factual
-   Generate irrelevant or repetitive outputs

We are aware of the biases and potential problematic/toxic content that current pretrained large language models exhibit: more specifically, as probabilistic models of (Italian and English) languages, they reflect and amplify the biases of their training data.
For more information about this issue, please refer to our survey:

## How to use Minerva with Hugging Face transformers

```python
import transformers
import torch

model_id = "sapienzanlp/Minerva-7B-instruct-v1.0"

# Initialize the pipeline.
pipeline = transformers.pipeline(
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
    device_map="auto",
)

# Input text for the model.
input_conv = [{"role": "user", "content": "Qual è la capitale dell'Italia?"}]

# Compute the outputs.
output = pipeline(
  input_conv,
  max_new_tokens=128,
)

output
```

    [{'generated_text': "La capitale dell'Italia è la città di Roma, che si trova a [...]"}]
    

## Model Architecture

Minerva-7B-base-v1.0 is a Transformer model based on the [Mistral](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.1) architecture.

### Online DPO Training

This model card is for our DPO model. Direct Preference Optimization (DPO) is a method that refines models based on user feedback, similar to Reinforcement Learning from Human Feedback (RLHF), but without the complexity of reinforcement learning. Online DPO further improves this by allowing real-time adaptation during training, continuously refining the model with new feedback. For training this model, we used the [Hugging Face TRL](https://github.com/huggingface/trl) library and Online DPO, with the [Skywork/Skywork-Reward-Llama-3.1-8B-v0.2](https://huggingface.co/Skywork/Skywork-Reward-Llama-3.1-8B-v0.2) model as the judge to evaluate and guide optimization. For this stage we used just the prompts from HuggingFaceH4/ultrafeedback_binarized (English), efederici/evol-dpo-ita (Italian) and Babelscape/ALERT translated to Italian, with additional manually curated data for safety.

For more details, please check [our tech report](https://nlp.uniroma1.it/minerva/blog#from-a-base-model-to-an-instruct-model).

## Model Evaluation

For Minerva's evaluation process, we utilized [ITA-Bench](https://huggingface.co/collections/sapienzanlp/ita-bench-italian-benchmarks-for-llms-66337ca59e6df7d7d4933896), a new evaluation suite to test the capabilities of Italian-speaking models. 
ITA-Bench is a collection of 18 benchmarks that assess the performance of language models on various tasks, including scientific knowledge, 
commonsense reasoning, and mathematical problem-solving.

 -->
## Tokenizer Fertility

The tokenizer fertility measures the average amount of tokens produced per tokenized word.
A tokenizer displaying high fertility values in a particular language typically indicates that it segments words in that language extensively.
The tokenizer fertility is strictly correlated with the inference speed of the model with respect to a specific language, 
as higher values mean longer sequences of tokens to generate and thus lower inference speed.

**Fertility computed over a sample of Cultura X (CX) data and Wikipedia (Wp):**

| Model | Voc. Size | Fertility IT (CX) | Fertility EN (CX) | Fertility IT (Wp) | Fertility EN (Wp) |
| --- | --- | --- |--- | --- |--- |
