蚂蚁集团AI安全实验室开源内生式安全护栏技术SingProbe。它不同于外挂式审核，复用基座模型推理隐藏状态，以不足0.5%额外算力实现token级实时风险评估，可同步完成意图分类、安全检测与幻觉识别，在医疗等高风险场景可在输出前毫秒级阻断。目前已适配29个主流大模型。
7月22日，地平线与大众深化合作，通过合资公司酷睿程采用白盒授权，基于地平线AI基座大模型自主开发智驾方案，地平线底层能力成为大众在华智驾大脑。
AI编程领域格局生变：众厂恋战L2代码补全，AIGCode以全栈方案谋求代际跃升。其核心洞察是大模型之殇在基座而非微调，借AutoCoder.cc剑指L3级自主编程。
近日马斯克在社交平台宣布，新一代大语言模型Grok 4.5已在SpaceX和特斯拉启动内部私测，从实验室迈向复杂工业场景。该模型以1.5万亿参数V9架构为基座，引入AI编程工具Cursor进行补充训练，以增强逻辑推理能力，推动AI在航天与汽车领域实际部署。
