Aya ExpansevsAya 23 35B

Aya Expanse, developed by Cohere through the Cohere For AI research initiative, is a multilingual open-source model with 32 billion parameters and a 128K token context window supporting 23 languages. Building on Aya 23, it substantially extends context length and improves quality across diverse languages. The model demonstrates strong cross-lingual transfer, enabling tasks like translation, summarization, and question answering across language pairs with limited parallel training data. Its 128K context window makes it suitable for processing long documents in languages where few other models offer extended context. Free and open-source, Aya Expanse aims to democratize access to capable multilingual AI. The model is particularly valuable for researchers and organizations working in lower-resource languages that receive minimal attention from major commercial AI providers.

Aya 23 35B, developed by Cohere through the Cohere For AI research initiative, is an open-source multilingual model with 35 billion parameters and an 8K token context window supporting 23 languages. The model was developed with contributions from researchers worldwide, focusing on extending quality AI capabilities to lower-resource languages that mainstream models underserve. Aya 23 35B performs well on multilingual benchmarks, particularly for languages in Africa, South Asia, and Southeast Asia where few commercial alternatives exist. Free and open-source, it can be fine-tuned and deployed for language-specific applications without cost. The model represents Cohere's commitment to democratizing AI access globally, providing a foundation for researchers and developers working in languages outside the English-Chinese-European focus of most commercial models.
