## Model description

**Ǎguila-7B** is a transformer-based causal language model for Catalan, Spanish, and English. 
It is based on the [Falcon-7B](https://huggingface.co/tiiuae/falcon-7b) model and has been trained on a 26B token 
trilingual corpus collected from publicly available corpora and crawlers.

More information available in the following post from Medium.com: Introducing Ǎguila, a new open-source LLM for Spanish and Catalan (https://medium.com/@mpamies247/introducing-a%CC%8Cguila-a-new-open-source-llm-for-spanish-and-catalan-ee1ebc70bc79)


## Intended uses and limitations

The **Ǎguila-7B** model is ready-to-use only for causal language modeling to perform text-generation tasks. 
However, it is intended to be fine-tuned for downstream tasks.

## How to use

Here is how to use this model:

```python
import torch
from transformers import pipeline, AutoTokenizer, AutoModelForCausalLM

input_text = "El mercat del barri és fantàstic, hi pots trobar"

model_id  = "projecte-aina/aguila-7b"
tokenizer = AutoTokenizer.from_pretrained(model_id)
generator = pipeline(
    "text-generation",
    model=model_id,
    tokenizer=tokenizer,
    torch_dtype=torch.bfloat16,
    trust_remote_code=True,
    device_map="auto",
)
generation = generator(
    input_text,
    do_sample=True,
    top_k=10,
    eos_token_id=tokenizer.eos_token_id,
)

print(f"Result: {generation[0]['generated_text']}")
```

## Limitations and bias
At the time of submission, no measures have been taken to estimate the bias and toxicity embedded in the model. 
However, we are well aware that our models may be biased since the corpora have been collected using crawling techniques 
on multiple web sources. We intend to conduct research in these areas in the future, and if completed, this model card will be updated. 


## Language adaptation

We adapted the original [Falcon-7B](https://huggingface.co/tiiuae/falcon-7b) model to Spanish and Catalan by swapping the tokenizer and adjusting the embedding layer. 

The adaptation procedure is explained in [this blog post](https://medium.com/@mpamies247/ee1ebc70bc79).

## Training

### Training data

The training corpus consists of 26B tokens of several corpora gathered from web crawlings and public domain data.

The dataset has the following language distribution:

|Language|Percentage|
|--------|----------|
|   En   |  16.84%  |
|   Es   |  41.38%  |
|   Ca   |  41.79%  |

Note: A small amount of English data was kept to avoid catastrophic forgetting. 

## Training procedure

The training corpus has been tokenized using a byte version of [Byte-Pair Encoding (BPE)](https://github.com/openai/gpt-2) with a vocabulary size of 50,257 tokens. 
After training a new tokenizer and adapting [falcon-7b](https://huggingface.co/tiiuae/falcon-7b)'s embedding layer, the model was
further pre-trained in three target languages: Catalan, Spanish and English.

The training lasted a total of 320 hours on 8 NVIDIA H100 GPUs with 80GB RAM.
