近年来，Transformer 架构在自然语言处理领域取得了巨大成功，从机器翻译到文本生成，其强大的建模能力为语言理解与生成带来了前所未有的突破。 然而，随着模型规模的不断扩大和应用场景的日益复杂，传统 Transformer 架构逐渐暴露出缺陷，尤其是在处理长文本、关键信息检索以及对抗幻觉等任 务时，Transformer 常常因过度关注无关上下文而陷入困境，导致模型表现受限。 为攻克这一难题，来自微软和清华的研究团队提出了 DIFF Transformer ，一种基于差分注意力机制的创新基础模型架构。 其核心思想是通过计算两组 Softmax 注意力图的差值来放大对关键上下文的关注，同时消除注意力噪声干扰。DIFF Transformer 具备以下显著优势： 在语言建模任务中，DIFF Transformer 在模型大小、训练 token 数量等方面展现出了卓越的可扩展性，仅需约 65% 的模型规模或训练 token 数量即可 达到与传统 Transformer 相当的性能，大幅提升了语言模型通用表现。 在长文本建模、关键信息检索、数学推理、对抗幻觉、上下文学习、模型激活值量化等一系列任务中，DIFF T ...

机器之心报道 编辑：陈萍、+0 大型语言模型（LLMs）在广泛的自然语言处理（NLP）任务中展现出了卓越的能力。然而，它们迅速增长的规模给高效部署和推理带来了巨大障碍，特别是在计 算或内存资源有限的环境中。 例如，Llama-3.1-405B 在 BFloat16（16-bit Brain Float）格式下拥有 4050 亿个参数，需要大约 810GB 的内存进行完整推理，超过了典型高端 GPU 服务器（例如， DGX A100/H100，配备 8 个 80GB GPU）的能力。因此，部署该模型需要多个节点，这使得它昂贵且难以获取。 本文，来自莱斯大学等机构的研究者提出了一种解决方案， 可以 将任何 BFloat16 模型压缩到原始大小的 70%，同时还能在任务上保持 100% 的准 确性。 论文标题： 70% Size, 100% Accuracy: Lossless LLM Compression for Efficient GPU Inference via Dynamic-Length Float 为了应对 LLM 不断增长的模型尺寸，通常会采用量化技术，将高精度权重转换为低位表示。这显著减少了内存 ...

Z Highlights 姚顺 雨 是斯坦福大学自然语言处理研究员， OpenAI 员工 ，专注于强化学习与语言模型融合研究。本文译自姚顺 雨 于 2025 年 4 月 10 日发布的英文博客 《 The Second Half 》，内容整合了他在斯坦福课程 CS224N 及哥伦比亚大学前沿论坛的核心演讲观点。 我们正处于AI的中场阶段。几十年来，AI的核心一直是开发新的训练方法和模型。这条路奏效了：从在国际象棋和围棋上击败世界冠军，到在SAT和律师 资格考试中超越大多数人类，甚至赢得IMO和IOI金牌。 这些载入史册的里程碑——DeepBlue、AlphaGo、GPT-4，以及o系列模型——背后是AI方法的根 本性创新：搜索、深度强化学习、模型规模化，以及推理。 一切都在不断变得更好。 那现在究竟发生了什么变化？用三个词概括：强化学习终于奏效了。更准确地说：强化学习终于具备了泛化能力。经历了多次重大的绕行与一系列里程碑 之后，我们终于找到了一个通用的有效配方，能够利用语言和推理解决各种各样的强化学习任务。哪怕是在一年前，如果你告诉大多数AI研究人员，一个 统一的方法可以同时解决软件工程、创意写作、IMO级别 ...

Global streaming giant Netflix Inc. (NFLX) has become a new icon for defensive picks by investors amid the Trump administration's tariff-led severe volatility on Wall Street. In the recently reported first-quarter 2025 results, NFLX handsomely beat the Zacks Consensus Estimate for bottom line while the top line was mostly in line with the consensus mark.
