The Canadian connection
Cohere traces its beginnings to Toronto in 2019. Its work includes foundation models and AI products for businesses, alongside an open-science research initiative.
A multilingual research release
In May 2024, Cohere introduced Aya 23 as a family of generative language models covering 23 languages. The release included versions with 8 billion and 35 billion parameters and made model weights available. This file describes that particular release, not the newest model in the Aya family.
Reading the numbers
Language count describes coverage; parameter count describes model size. Neither number, on its own, answers whether a model will be useful for a particular task. For a practical evaluation, identify the exact model, language and type of work, then inspect its documentation and test results.
