Code and resources for mT5, a massively multilingual text-to-text transformer pretrained on the mC4 corpus covering 101 languages. It reproduces the mT5 paper experiments and relies on the t5 library for training and fine-tuning.

Use cases

• fine-tune a multilingual text-to-text transformer on my own NLP task
• reproduce the mT5 paper experiments
• train a seq2seq model that works across 101 languages
• get state-of-the-art zero-shot cross-lingual classification and QA
• download pretrained mT5 checkpoints of various sizes
• do cross-lingual question answering or NER with a pretrained model

When to choose

• you need a pretrained multilingual encoder-decoder model covering many languages
• you want to reproduce or extend the mT5 paper using the t5 ecosystem
• you need cross-lingual transfer for classification, structured prediction, or QA

When to avoid

• you only need English-language models
• you want a maintained library with frequent updates and broad community support
• you need inference-only usage without the t5 library dependency
• you want a lightweight model for resource-constrained environments
