美股異動|百度大升超9%,發佈文心大模型4.5及X1
百度(BIDU.US)收升9.01%,報102.27美元。百度近日正式發佈文心大模型4.5和文心大模型X1,並已在文心一言網站上線,免費向用户開放。文心大模型4.5是百度首個原生多模態大模型,在多模態理解、文本和邏輯推理等方面有顯著提升,多項測試表現優於GPT4.5,API調用價格僅為GPT4.5的1%。文心大模型X1則是一款性能上對標DeepSeek-R1的深度思考模型,並支持多模態及多工具調用能力,API調用價格約為R1的一半。花旗表示,百度可能會通過利用其雲基礎設施和千帆平台來保持其競爭力,即使進入門檻的降低加劇了人工智能模型之間的競爭。分析師Alicia Yap和Nelson Cheung在一份報吿中寫道:“自從DeepSeek-R1在大約兩個月前顛覆性地首次推出以來,幾乎每週/每隔幾天,都會有各種llm、人工智能應用程序和人工智能代理的新版本或升級版本,花旗認為這可能會推動百度加快了其發佈計劃。”(格隆匯)
