Aya Expanse 32B

Cohere · 2024-10-24 · 32.3B parameters

Aya Expanse 32B is Cohere For AI and Cohere's open-weight multilingual instruction-tuned text model, released on October 24, 2024 for 23 languages. Built on Cohere's Command-series 32B base, its post-training combines supervised fine-tuning with multilingual data arbitrage, iterative offline-and-online multilingual preference training, safety tuning, and weighted model merging. Cohere documents 128K-context support despite the released configuration's 8,192 max-position setting; a maintainer attributes that setting to a buffer-materialization constraint in the original implementation.
