Meta, Microsoft, Alphabet, and Amazon Just Delivered Incredible News for Nvidia Stock Investors
The Motley Fool· 2025-05-05 22:05
Core Viewpoint - Nvidia has faced significant stock volatility in 2025, with a year-to-date decline of 15%, primarily due to concerns over potential demand reduction for its data center chips amid tariff implications [1][9] Group 1: Tariff Impact and Customer Spending - Although semiconductors are exempt from aggressive tariffs, Nvidia's customers may still experience increased costs, potentially leading to reduced capital expenditures [2] - Major customers like Meta, Microsoft, Alphabet, and Amazon have provided positive updates on their AI spending plans for 2025, indicating continued demand for Nvidia's chips [2][12] - Meta raised its 2025 capex forecast to $64 billion to $72 billion, Microsoft plans to spend around $80 billion, Alphabet maintains a $75 billion forecast, and Amazon is set to spend approximately $105 billion [12] Group 2: Nvidia's Technological Advancements - Nvidia's H100 GPU was the leading AI data center chip in 2023 and most of 2024, but has been succeeded by the more advanced Blackwell and Blackwell Ultra architectures, with the latter offering up to 50 times faster AI inference in specific configurations [4][6] - The upcoming Rubin GPUs, expected in 2026, are projected to deliver 3.3 times more compute performance, further enhancing Nvidia's position in the AI market [7] Group 3: Market Position and Future Growth - Nvidia generated $115.2 billion in data center revenue for fiscal 2025, marking a 142% increase from the previous year, with predictions of data center spending exceeding $1 trillion annually by 2028 [14] - Demand for Nvidia's chips currently exceeds supply, making it difficult for companies to cancel orders without risking a competitive disadvantage in AI [16] - Nvidia's stock is viewed as a buying opportunity, trading at a P/E ratio of 39, significantly lower than its 10-year average above 50 [11]
DeepSeek开源新模型,数学推理能力大提升
Hu Xiu· 2025-05-01 00:48
赶在五一假期前夕,DeepSeek给我们送出一份惊喜大礼。 延续一贯的开源节奏,DeepSeek在Hugging Face正式发布DeepSeek-Prover-V2,并同步上线模型卡及示例代码。此次共推出两个版本: *核心贡献者†在DeepSeek-AI实习期间完成的工作 据官方论文披露,DeepSeek-Prover-V2的训练核心是"递归+强化学习"的组合:即先由DeepSeek-V3拆解复杂定理,生成一系列子目标和推理思路;再通过 GRPO算法,从多种候选方案中自动学习如何选出最优解。 模型特别引入了两种互补的"解题风格": DeepSeek-Prover-V2-7B:基于上一代V1.5模型,支持最长32K上下文输入; DeepSeek-Prover-V2-671B:在DeepSeek-V3-Base基础上训练,推理性能最强。 训练过程分为两阶段,在第一阶段,研究人员主要训练快速模式,采用"专家迭代"方法:模型先尝试解决难题,成功的答案再作为新数据反哺模型,不断 打磨自己的能力。 待快速模式趋于稳定后,研究人员进入第二阶段,开始训练更复杂的逻辑推理能力。他们将DeepSeek-V3的数学知识迁移到新模 ...

自动调整推理链长度,SCoT来了!为激发推理能力研究还提出了一个新架构
量子位· 2025-03-13 03:28
SCoT团队 投稿 量子位 | 公众号 QbitAI 不怕推理模型简单问题过度思考了,能 动态调整CoT的新推理范式SCoT来了! SCoT,即自 结构化推理链 (Self-structured Chain of Thought ) 。 它通过 将推理过程分解为最小语义原子步骤 ,能动态生成适配不同复杂度问题的CoT结构,解决了现有方法在推理多样性和效率上的不足。 另外,为了激发推理能力,研究人员还提出了 AtomThink ,这是一个包含数据构造、训练、推理和评估的全过程框架, 用来提升多模态大 模型在复杂推理任务上的表现 。 实验中,SCoT使模型能根据问题复杂度自动调整推理链长度,复杂问题的推理步骤更长。 在多个数据集上,AtomThink框架显著提升了基线模型的准确率,数据利用效率和推理效率也表现出显著优势。 并且,原子能力评估揭示了多模态模型在不同推理能力上的分布特征,为理解多模态推理模式提供了新视角。 这项研究由来自中山大学、香港科技大学、上海交通大学、香港大学、华为诺亚方舟实验室的研究人员联合提出,以下是更多细节。 SCoT、AtomThink长啥样? 当前,结构化和非结构化CoT面临一定的挑战 ...
