## Model description |
|
|
|
The **Cǒndor-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. |
|
|
|
|
|
## Intended uses and limitations |
|
|
|
The **Cǒndor-7B** model is ready-to-use only for causal language modeling to perform text-generation tasks. However, it is intended to be fine-tuned on a generative downstream task. |
|
|
|
## How to use |
|
|
|
Here is how to use this model: |
|
|
|
```python |
|
import torch |
|
import transformers |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
input_text = "Maria y Miguel no tienen ningún " |
|
model = "BSC-LT/condor-7b" |
|
tokenizer = AutoTokenizer.from_pretrained(model) |
|
|
|
pipeline = transformers.pipeline( |
|
"text-generation", |
|
model=model, |
|
tokenizer=tokenizer, |
|
torch_dtype=torch.bfloat16, |
|
trust_remote_code=True, |
|
device_map="auto", |
|
) |
|
generation = pipeline( |
|
input_text, |
|
max_length=200, |
|
do_sample=True, |
|
top_k=10, |
|
eos_token_id=tokenizer.eos_token_id, |
|
) |
|
|
|
print(f"Result: {generation['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 model to Spanish and Catalan by swapping the tokenizer and adjusting the embedding layer. The adaptation procedure is explained in this [blog](https://medium.com/@mpamies247/ee1ebc70bc79). |
|
|
|
### New vocabulary |
|
We trained a new BPE Tokenizer for the Catalan and Spanish languages (equal representation). We shuffled a small amount of English in the mixture (since English is in the model training data). |
|
The resulting data has the following language distribution: |
|
|
|
|Language|%| |
|
|---|---| |
|
|En|16.84%| |
|
|Es|41.38%| |
|
|Ca|41.79%| |
|
|
|
This reduced drastically the number of tokens required to tokenize a text in the target language while the English tokenization shows a small increase. |
|
|
|
### Embedding Layer Initialization |
|
In order to fully take advantage of the English Pre-Training of the original Falcon model, we decided to re-use the embedding weights of the original model for those tokens shared between the two Tokenizers (the new and the old one). The rest of the embedding weights are initialized as the mean value of the weights of the original Tokenizer. |
|
|
|
|
|
## Training |
|
|
|
### Training data |
|
|
|
The training corpus consists 26B tokens of several corpora gathered from web crawlings and public corpora. |

## Training procedure |
|
|
|
The training corpus has been tokenized using a byte version of [Byte-Pair Encoding (BPE)](https://github.com/openai/gpt-2) used in the original [RoBERTA](https://github.com/pytorch/fairseq/tree/master/examples/roberta) model with a vocabulary size of 50,257 tokens. Once the model has been successfully initialized, we continued its pre-training in the three target languages: Catalan, Spanish, and English. We kept a small amount of English in order to avoid catastrophic forgetting. The training lasted a total of 96 hours with 8 NVIDIA H100 GPUs of 80GB of RAM. |
