DeepSeek于4月24日发布新一代大模型DeepSeek-V4，性能比肩顶级闭源模型，成为开源AI里程碑。它支持100万tokens超长上下文，适用于长文档分析、代码生成和多轮任务。同时推出轻量版Flash和标准版，分别满足快速迭代与深度应用需求。
谷歌推出基于Gemini 3.1Pro架构的Deep Research与Deep Research Max两款AI研究代理，现已开放付费预览。它们旨在自动化复杂研究流程，推动AI从简单搜索向具备深度推理的“长时计算”演进。标准版注重高效低延迟，适合实时对话；Max版则优先研究深度与准确性，适用于复杂任务。
华为4月20日发布Pura90系列、Pura X Max折叠手机及首款鸿蒙AI眼镜，并公布价格。尽管存储芯片涨价，华为仍保持稳定定价策略，Pura90标准版起售价与上代持平，展现市场竞争力。
DeepSeek V4正进行灰度测试，界面显示模型在架构、交互和多模态能力上均有突破。核心亮点是“三足鼎立”的新功能架构：快速版侧重轻量化日常响应，标准版平衡性能与效率，专业版则面向复杂任务。这标志着产品矩阵的全面进化。
