Multilingual AI Research
Aya provides AI researchers a groundbreaking foundation to accelerate multilingual AI progress. Aya is one of the largest open science endeavors in machine learning to date – redefining the research landscape by collaborating with independent researchers from across the globe. The result is a fully open-sourced dataset and model.
Aya Dataset: An Open-Access Collection for Multilingual Instruction Tuning
The Aya Collection stands as the most extensive assembly of multilingual instruction fine-tuning datasets to date, featuring 513 million prompts and completions across 114 languages. We fully open-source the collection, which includes rare, human-curated annotations from fluent speakers worldwide.
Aya Model: An Instruction Finetuned Open-Access Multilingual Language Model
The Aya Model is a massively multilingual language model capable of following instructions in 101 languages. Developed using a diverse mix of instructions from the Aya dataset and collection among others, it achieves state-of-the-art performance across numerous multilingual benchmarks.

A Step Forward For Multilingual Generative AI
Evaluations for Aya 101, our original, massively multilingual research LLM.
Human evaluation of the Aya model shows consistent gains
The Aya model follows instructions and generates responses of significantly higher quality than mT0x. Based on human evaluations from professional annotators who compared model responses to instructions given in multiple languages, the Aya model is preferred 77% of the time on average.
