MedMT5: An Open-Source Multilingual Text-to-Text LLM for The Medical Domain
Model Card for MedMT5-large
We present MedMT5, the first open-source text-to-text multilingual model for the medical domain. MedMT5 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.

How to Get Started with the Model
You can load the model using
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
tokenizer = AutoTokenizer.from_pretrained("HiTZ/MedMT5-xl")
model = AutoModelForSeq2SeqLM.from_pretrained("HiTZ/MedMT5-xl")
The model has been trained using the T5 masked language modeling tasks. You need to finetune the model for your task.

Ethical Statement
Our research in developing MedMT5, 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.
