苹果正加速研发代号“Baltra”的自研AI服务器芯片，预计2027年投入使用，旨在减少对英伟达的依赖。该项目与博通合作，专注于核心网络传输技术，标志着苹果向算力基础设施领域深化垂直整合战略。
MIT科学家通过15年研究，首次绘制出人脑语言网络的毫米级概率图。该网络体积小但功能强大，专门负责词语意义映射和句子拼装，与思考、情绪模块完全分离。通过1400次fMRI扫描，研究确认了“语言芯片”的存在。
OpenAI与博通合作开发10千瓦AI加速器，旨在提升计算能力应对市场需求。OpenAI负责芯片设计，博通提供以太网、PCIe等网络组件，分工明确提高开发效率。
国家网信办7月31日约谈英伟达公司，就其H20算力芯片存在的**"追踪定位"和"远程关闭"**安全风险问题要求说明。此前有报道称该芯片存在严重漏洞，美国专家也证实相关技术已成熟。网信办依据《网络安全法》等法规，要求英伟达提交详细说明及证明材料。此次约谈正值美国议员呼吁出口芯片须配备追踪功能之际。
