LOLA — An Open-Source Massively Multilingual Large Language Model

Model Description

Developed by: DICE Research Group (https://dice-research.org/) @ Paderborn University (https://www.uni-paderborn.de/)
Model type: GPT2 style (decoder-only) with alternating sparse Mixture-of-Experts layers
Number of Experts: 16
Model Size: 1.3 Billion (active*) / 7.4 Billion (total)
Language(s) (NLP): 160+
License: CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/)
Repository: https://github.com/dice-group/LOLA

_{* The number of parameters a model utilizes per token (ref: Du et al, 2022). This distinction is crucial for understanding the efficiency and performance of MoE models.}

How to Get Started with the Model

This pre-trained (causal language modeling) model can only be used for text-generation and requires further fine-tuning on downstream tasks.

How to use

You can use this model directly with a pipeline for text generation.

>>> from transformers import pipeline

>>> generator = pipeline('text-generation', model="dice-research/lola_v1", trust_remote_code=True)
>>> generator("The quick brown fox", max_length=13)
[{'generated_text': 'The quick brown fox jumps over the lazy dog.'}]

To use the top-k sampling, please set do_sample to True.

Note: The tokenizer used in the model comes from mGPT (https://github.com/ai-forever/mgpt)
