百度(BIDU.US)收涨9.01%,报102.27美元。百度近日正式发布文心大模型4.5和文心大模型X1,并已在文心一言网站上线,免费向用户开放。文心大模型4.5是百度首个原生多模态大模型,在多模态理解、文本和逻辑推理等方面有显著提升,多项测试表现优于GPT4.5,API调用价格仅为GPT4.5的1%。文心大模型X1则是一款性能上对标DeepSeek-R1的深度思考模型,并支持多模态及多工具调用能力,API调用价格约为R1的一半。
花旗表示,百度可能会通过利用其云基础设施和千帆平台来保持其竞争力,即使进入门槛的降低加剧了人工智能模型之间的竞争。分析师Alicia Yap和Nelson Cheung在一份报告中写道:“自从DeepSeek-R1在大约两个月前颠覆性地首次推出以来,几乎每周/每隔几天,都会有各种llm、人工智能应用程序和人工智能代理的新版本或升级版本,花旗认为这可能会推动百度加快了其发布计划。”(格隆汇)
