Medical mT5: An Open-Source Multilingual Text-to-Text LLM for the Medical Domain


# Model Card for MedMT5-xl

We present Medical mT5, the first open-source text-to-text multilingual model for the medical domain. Medical mT5 is an encoder-decoder model developed by continuing the training of publicly available mT5 checkpoints on medical domain data for English, Spanish, French, and Italian.

# Model Description - **Developed by**: Iker García-Ferrero, Rodrigo Agerri, Aitziber Atutxa Salazar, Elena Cabrio, Iker de la Iglesia, Alberto Lavelli, Bernardo Magnini, Benjamin Molinet, Johana Ramirez-Romero, German Rigau, Jose Maria Villa-Gonzalez, Serena Villata and Andrea Zaninello - **Contact**: [Iker García-Ferrero](https://ikergarcia1996.github.io/Iker-Garcia-Ferrero/) and [Rodrigo Agerri](https://ragerri.github.io/) - **Website**: [https://univ-cotedazur.eu/antidote](https://univ-cotedazur.eu/antidote) - **Funding**: CHIST-ERA XAI 2019 call. Antidote (PCI2020-120717-2) funded by MCIN/AEI /10.13039/501100011033 and by European Union NextGenerationEU/PRTR - **Model type**: text2text-generation - **Language(s) (NLP)**: English, Spanish, French, Italian - **License**: apache-2.0 - **Finetuned from model**: mT5 ## How to Get Started with the Model You can load the model using ```python from transformers import AutoTokenizer, AutoModelForSeq2SeqLM tokenizer = AutoTokenizer.from_pretrained("HiTZ/Medical-mT5-xl") model = AutoModelForSeq2SeqLM.from_pretrained("HiTZ/Medical-mT5-xl") ``` The model has been trained using the T5 masked language modelling tasks. You need to finetune the model for your task.

## Ethical Statement

Our research in developing Medical mT5, a multilingual text-to-text model for the medical domain, has ethical implications that we acknowledge. Firstly, the broader impact of this work lies in its potential to improve medical communication and understanding across languages, which can enhance healthcare access and quality for diverse linguistic communities. However, it also raises ethical considerations related to privacy and data security. To create our multilingual corpus, we have taken measures to anonymize and protect sensitive patient information, adhering to data protection regulations in each language's jurisdiction or deriving our data from sources that explicitly address this issue in line with privacy and safety regulations and guidelines. Furthermore, we are committed to transparency and fairness in our model's development and evaluation. We have worked to ensure that our benchmarks are representative and unbiased, and we will continue to monitor and address any potential biases in the future. Finally, we emphasize our commitment to open source by making our data, code, and models publicly available, with the aim of promoting collaboration within the research community.
