## Please note:

# Model Card for Minerva-7B-base-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-base-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)

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

*This section identifies foreseeable harms and misunderstandings.*

This is a foundation model, not subject to alignment. Model may:

-   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-base-v1.0"

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

# Input text for the model.
input_text = "La capitale dell'Italia è"

# Compute the outputs.
output = pipeline(
  input_text,
  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 architecture.

## Model Training

Minerva-7B-base-v1.0 was trained using [llm-foundry 0.8.0](https://github.com/riccorl/llm-foundry) from [MosaicML](https://mosaicml.com/). The hyperparameters used are the following:

| Model Name | Optimizer | lr | betas | eps | weight decay | Scheduler | Warmup Steps | Batch Size (Tokens) | Total Steps |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| Minerva-350M-base-v1.0 | Decoupled AdamW | 2e-4 | (0.9, 0.95) | 1e-8 | 0.0 | Cosine | 2% | 4M | 16,690 |

| Minerva-3B-base-v1.0 | Decoupled AdamW | 2e-4 | (0.9, 0.95) | 1e-8 | 0.0 | Cosine | 2% | 4M | 157,357 |
| Minerva-7B-base-v1.0 | AdamW | 3e-4 | (0.9, 0.95) | 1e-5 | 0.1 | Cosine | 2000 | 4M | 591,558 |

## Model Evaluation

We assessed our model using the [LM-Evaluation-Harness](https://github.com/EleutherAI/lm-evaluation-harness) library, which serves as a comprehensive framework for testing generative language models across a wide range of evaluation tasks.

All the reported benchmark data was already present in the LM-Evaluation-Harness suite.

_Scores will be available at later stage._

## 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) |
| --- | --- | --- |--- | --- |--- |
| Mistral-7B-v0.1 | 32000 | 1.87 | 1.32 | 2.05 | 1.57 |
| gemma-7b | 256000 | 1.42 | 1.18 | 1.56 | 1.34 |
| Minerva-3B-base-v1.0 | 32768 | 1.39 | 1.32 | 1.66 | 1.59 |
| Minerva-7B-base-v1.0 | 51200 | - | - | - | - |
