3 Training and Baselines

  1. Why did Aya fine-tune mT5-XXL rather than a newer model like Llama?
    Although mT5 (2019) is weaker than recent models, it was pretrained on 1T tokens covering exactly 101 languages; adapting embeddings during instruction tuning to languages unseen in pretraining is known to be hard, and recent strong models were English-centric.

  2. How were Aya’s data sources weighted within the 25M-example training budget?
    Three ablations upweighted human-annotated, translated or templated data. Human annotations were only 0.7% of the budget at natural rates, so upweighting them (to 25%) means repeating each example many times; translation-heavy weighting became the final model.
