Cohere For AI 發表全新開源多語言模型家族 Aya Expanse（包含 8B 與 32B 參數版本），支援 23 種語言。該模型透過創新的資料套利、合成資料生成與多語言偏好對齊技術，在多項基準測試中擊敗了 Llama 3.1、Gemma 2 等同級甚至更大規模的模型，為全球多語言 AI 研究樹立了新標竿。
Cohere For AI (C4AI) has officially launched Aya Expanse, a family of open-weight models designed specifically for multilingual tasks. The family includes two parameter sizes — 8B (8 billion) and 32B (32 billion) — and is now available for download on Hugging Face. The goal of Aya Expanse is to address the pain point of mainstream large language models (LLMs) performing poorly in non-English languages (particularly those with fewer resources), and to bring top-tier multilingual capabilities to researchers and developers around the world.
