# Model Card for Model ID

<!-- Provide a quick summary of what the model is/does. -->
**LOLA**: Large and Open Source Multilingual 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 Mixture-of-Experts layers
- **Language(s) (NLP):** 160+
- **License:** Coming soon
- **Repository:** https://github.com/dice-group/LOLA-Megatron-DeepSpeed

## 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.

```python
>>> 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)
