给一个全国的大学生 AI比赛做评委,看了几个项目。 从一个视角窥探当下大学生AI 使用的现状: 1、 交付物都是AI 的,设计文档纯 AI 写的,很空洞,我不喜欢,哪怕你自己写 100 个字,我都给你满分了,看不到思考 2、 路演的视频,AI 配音、剪映剪辑也不太会用,没有声音 3、demo UX/UI 一点美感都没有,切切实实感受到了我们的美学真的是落后,或者说这块还真得靠自己了,没人教! 大家一定要注意! 当所有人都可以用 AI 去做什么事情的时候,这个时候反而越要反其道而行之。特别是这种大赛 其次,路演 demo 这块的演讲能力要培养起来,搞 AI 材料,我是不是也搞个 agent 直接把链接丢给 AI,让他去看啊?😂 我到底是 AI 还是人啊?对方能回答下吗?喂喂喂???

[开源学习资源] AI Engineering from Scratch 59.8K ⭐️ 作者 @ghumare64 课程共 20 个阶段,以 Python 为主要编程语言,主张在导入任何框架之前,先用纯数学把每个算法手写一遍。 课程地址: 开源地址: 它和常见教程的本质区别 ? 大多数 AI 教程是“API 驱动”的:装个库、调个接口、跑个 demo。这个项目反其道而行,每节课遵循固定的六段结构: Motto → Problem → Concept → Build It → Use It → Ship It 以 Phase 10 的一节课「Tokenizers: BPE, WordPiece, SentencePiece」 为例,这个格式是真实落地的,而且写作质量相当高: · Problem 部分不讲废话,直接从代价切入:“你的 LLM 不读英语,它读整数。分词器决定这些整数是承载意义还是浪费意义”,然后解释为什么 tokenization 不是预处理,它是架构的一部分(影响上下文窗口利用率、API 计费、推理速度)。 · Concept 部分用“三种失败的方案和一种胜出的方案”来讲演化逻辑:词级切分(词表爆炸、[UNK] 问题)→ 字符级切分(序列过长)→ 子词切分(BPE 的折中),并配上真实语料上 BPE 逐步合并的手工演算。 每节约 3000+ 词,带 Mermaid 图、可运行代码和测试。 另外两个设计值得强调: · 每节课产出一个可复用的 artifact,一个 prompt、一个 skill、一个 agent 或一个 MCP server。学完整个课程,你手里有 523 个可展示的作品,不是 523 个跑完就扔的 notebook。 · 强调“证据留存”:保留命令、退出码、输出,作为学习发生的证明。这明显吸收了工程实践中“可验证性”的思路。 # 课程结构:从线性代数到自主智能体集群 20 个阶段构成一条完整的上升曲线,咱们它分成五个大块来看: 基础层(Phase 0–2):环境与工具链、数学基础(线性代数/概率/微积分)、经典机器学习。这是给基础不牢的读者铺的路。 深度学习与感知层(Phase 3–6):神经网络核心、计算机视觉(一路讲到 NeRF、高斯泼溅、世界模型,这已经超出一般教程的覆盖范围)、NLP、语音。 生成与决策层(Phase 7–9):Transformer 深挖、生成式 AI(GAN、扩散模型、flow matching)、强化学习。 LLM 层(Phase 10–12):这是全课程的重心之一。Phase 10 的目录我逐条看过,它不只是“从零实现 GPT”这种常规内容,还包含了相当前沿的论文级主题:DeepSeek-V3 架构走读、DualPipe 并行策略、Native Sparse Attention(NSA)、多 token 预测、Jamba 的 SSM-Transformer 混合架构、 speculative decoding 等。Phase 11 转向应用侧(RAG、LoRA、MCP、可观测性),Phase 12 覆盖多模态(从 CLIP 到 computer-use agent)。 智能体层(Phase 13–16):工具与协议(MCP、A2A、Agent Skills)、54 节课的 agent 工程、自主系统与安全、多智能体集群。这一层的分量很能说明项目的判断:它认为 AI 工程的重心正在从“训模型”转向“构建可靠协作的智能体”。 收尾(Phase 17–19):生产基础设施、伦理与对齐、毕业设计。 # 生态与周边:不只是一个课程仓库 网站:带浏览器本地存储的学习进度追踪、术语表、课程目录和路线图。 六卷本书籍:课程内容由 CI(pandoc)自动构建成 EPUB/PDF,附在 GitHub Releases 上,课程即书,且随仓库持续更新。 Agent 导师模式:运行 npx skills add rohitg00/ai-engineering-from-scratch,可以把整个课程装进 Claude Code、Codex 等编码智能体,变成一个带分级测验(placement quiz)和个性化路径的交互式导师,学习进度写在 LEARNING.md 里。这是“用你正在学的工具来学”的巧妙闭环。 认证备考:5 条备考路径、67 节课、505 道练习题,覆盖 Anthropic 的 Claude 认证和 Agentic AI Foundation 的 MCPA。项目明确声明与这些考试机构无关联,只是独立的备考材料。 12 种语言的翻译(含中文),以及四条核心学习路径(构建与部署 AI 应用、软件工程基础、Agent 辅助工程、产品判断与交付)供不同目标的人选路。

一个离谱的互联网文化碰撞正在发生: 原本为电竞主播 FaZe Jev 建立的 r/jev 社区,突然被一群分享 AI 电脑操作 Demo 的极客淹没。 老用户一脸懵:“这里到底发生了什么?我的 Jev 去哪了?”😂

I asked AI what America would look like after 50 years of Democrat rule. Apparently AI and I had a very similar picture in mind.

Chamath explains the political calculus behind Obama’s anti AI speech “This is a very important moment for a very simple reason, which is that the world is about to endow 3-6 companies with about $10 trillion of wealth.” “And what Obama knows very well is that most of those companies are overwhelmingly left leaning. And what he also knows is that there is a huge portion of that money that will then get put into philanthropic and charitable causes that then he and the people around him will be beneficiaries of." “That is the truth. We already know this because we know that some of these frontier corporations actually ask you to sign up DAFTs and have a portion of your stock that you're willing to pledge. So this money is going to go to things other than consumption or savings. It's going to go into PACs, it's going to go into political movements, and they stand to disproportionately benefit." “So this has nothing to do with prosperity. This is a very simple political calculus. If you freeze frame the economy the way it is today, a handful of organizations that will disproportionately be able to affect the Democrats will win, they will capture the lion's share of the economic gains. And then they will help the Democrats win power. That's all this is."

Eight democracies. One message to Beijing. Australia, France, Germany, Japan, New Zealand, Poland, South Korea and the UK issued a joint statement on September 22 opposing any unilateral change to the Taiwan Strait status quo. It came out of a meeting on the sidelines of the UN General Assembly, where officials called today's security environment more volatile than a year ago. Their language was direct: "We encourage dialogue and oppose any unilateral attempts to change the status quo across the Taiwan Strait." The same day, the US, Japan and South Korea issued a separate statement making the same point, and also backing Taiwan's participation in international organizations. Taiwan's foreign ministry welcomed the statement and said it would keep building self-defense and deepen ties with democratic partners.

A curated collection of Claude Opus 5.5 videos and animations: demos, original posts, prompts and workflows. English / 中文.
Some new misalignment disclosures from OpenAI: • Last Sunday morning, one of our models was able to gain unauthorized access to the internet during RL training (~all inference for our most capable models remains stopped until we have hardened our systems further) • In May, a version of HPIM uploaded a employee's GitHub token to the internet, causing the model to be quarantined for two weeks • A new research finding, demonstrating that one can construct self-replicating prompt injections
