About Aya Expanse 8B

Aya Expanse 8B brings Cohere's 23-language multilingual approach to a small-model budget. Useful for edge deployments serving non-English users on hardware that can't accommodate the 32B variant.

The non-commercial license remains the main constraint; for research and education the model is one of the strongest small multilingual options available.
