網易有道發佈“子曰”大模型4.0，全面邁入全模態時代，實現文本、圖片、音頻高效融合交互。該版本以全量開源爲核心，向開發者社區開放核心技術，旨在降低AI落地成本與門檻。核心突破包括全模態融合交互、深層重構等維度，推動AI生態發展。
網易有道發佈“子曰”大模型4.0版本，全面升級至全模態時代，支持文本、圖片、音頻融合交互。核心的多模態模型和語音合成（TTS）模型正式開源，翻譯模型經技術重構，翻譯質量與效率顯著提升。多模態模型在視覺和數理領域達到SOTA水平，純文本數理難題性能行業領先。
網易有道宣佈自2025年8月28日起免費開放文檔翻譯功能，支持八種語言互譯，特別優化金融、計算機、醫學等專業領域翻譯。核心亮點是搭載自研“子曰”教育大模型，大幅提升翻譯質量和效率。
網易有道在ChinaJoy期間宣佈將於8月下旬推出新一代AI答疑筆，強化學科答疑功能。公司高級副總裁劉韌磊在CDEC高峯論壇上表示，AI與教育結合能提升教學效率，解決傳統教育痛點。自2023年推出"子曰"教育大模型後，有道持續探索AI應用，已開發虛擬口語教練Hi Echo等產品。新一代AI答疑筆將爲學生提供更智能的學習輔助，展現AI在教育領域的創新潛力。
支持虛擬人口語教練等
