PAGnol: An Extra-Large French Generative Model

PAGnol is a collection of large French language models, geared towards free-form text generation. With 1.5 billion parameters. PAGnol is based on the GPT architecture. PAGnol is the first language model trained by LightOn, in cooperation with the ALMAnaCH team of Inria.

These model were trained in early 2021 following the then scaling laws and using the exact same training data as the CamemBERT model trained on CCNet. We make it available for reproducibility purposes. They do not constitute the current state of the art nor are they aiming at it.

PAGnol was built by Julien Launay, E.L. Tommasone, Baptiste Pannier, François Boniface, Amélie Chatelain, Iacopo Poli, and Djamé Seddah. It is named after Marcel Pagnol (with PAG standing for pré-apprentissage génératif), and was trained on the IDRIS Jean Zay supercomputer thanks to a GENCI allocation.

The model was converted to the Hugging Face format by Wissam Antoun (ALMAnaCH's PhD student, co-supervised by Benoît Sagot and Djamé Seddah)

Usage

Using PAGnol with Huggingface

from transformers import pipeline

generator = pipeline('text-generation', model='lightonai/pagnol-medium', trust_remote_code=True)

output = generator(
    "Salut PAGnol, comment ça va ?",
    max_length=50,
    do_sample=True,
    temperature=0.7,
)[0]["generated_text"]

>>> "Très bien! Les jours d’été sont là ! Bientôt les premiers festivals..."

Using PAGnol with lairgpt

Head over to our GitHub repository to access our PyTorch inference code. Using PAGnol is as simple as running the following code:

from lairgpt.models import PAGnol

pagnol = PAGnol.medium()
pagnol("Salut PAGnol, comment ça va ?")

>>> "Très bien! Les jours d’été sont là ! Bientôt les premiers festivals..."
