About

Aya Expanse 8B is Cohere Labs' multilingual language model covering 23 languages (EN, FR, DE, ES, IT, PT, JA, KO, ZH, AR, EL, FA, PL, ID, CS, HE, HI, NL, RO, RU, TR, UK, VI), released Oct 2024. Weights are downloadable from Hugging Face but gated (request access, agree to non-commercial use) and licensed CC-BY-NC-4.0 — research and non-commercial use only. It is not open source and must not be described as such. For commercial multilingual use, Cohere's paid API models are the intended path.

Benchmarks

Provider-reported (Cohere Labs): win-rate charts in the model repo show Aya Expanse 8B beating comparable multilingual baselines across languages on Dolly-style and arena-hard-style evaluations — provider-reported, not independently re-verified.

Provider-reported unless a source says otherwise. Benchmarks are marketing-adjacent by nature — treat them as directional.
