Introducing Aya
A global initiative led by Cohere For AI to advance the state-of-art in multilingual AI and bridge gaps between people and cultures across the world. Aya is an open science project to create new models and datasets that expand the number of languages covered by AI, involving over 3,000 independent researchers across 119 countries.
The word Aya is derived from the Twi language meaning “fern” - a symbol of endurance and resourcefulness. Aya embodies our dedication to advancing multilingual AI.

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.

The numbers behind Aya, our family of massively multilingual research LLMs.
Advancing the state-of-art for global languages
The Aya Collection and our first Aya model, Aya 101, cover 101 languages. Half of these were completely under-served by pre-existing language models. Aya Expanse offers enhanced performance for 23 of these languages.
