百度宣佈將旗下文心相關網站合併爲全新“百度文心網站”，打造一站式AI服務超級入口，以降低用戶使用門檻並提升效率，其技術底層已升級爲文心5.1大模型。
百度發佈新一代文心大模型5.1，採用“多維彈性預訓練”技術，主打高性價比和強大搜索整合能力。該模型已上線百度千帆模型廣場和文心一言官網，面向企業用戶和開發者開放體驗，在AI競爭中展現國產大模型新突破。
百度文心一言5.1預覽版低調上線國際盲測平臺LMSYS Chatbot Arena，最新數據顯示其在總榜排名第13位。這標誌着百度核心模型進入新一輪快速迭代週期，開始接受全球用戶檢驗。雖然官方未公佈具體參數和架構細節，但基於以往迭代邏輯和競技表現，該版本在語義理解方面預計有所提升。
