这几天围绕 DeepSeek 发生的种种非常有趣。我自己凑巧在去年年底 V3 刚发布时就开始关注,陆陆续续读了一些他们的 paper,在过去一个月内看着西方大部分非从业人士从漠不关心和怀疑到去了解和赞美;直到这两天 R1 发布,somehow 导致 NVDA 市值一天蒸发 $600 billion,这中间观察到许多不同的 perspective 和人性的体现,实在精彩。

喧嚣过后想分享几点 takeaway:

1. V3 和 R1 的 technical report 读起来最大的感受是,里面轻描淡写地放了很多需要大量实验才能探明和得出的结论;而这些探索基本都需要大量硬核的 research engineering。这背后必然是一个人才密度极高的团队,而那才是在大模型几乎注定迟早要成为 commodity 的前景下一个公司真正的 moat。如梁文锋自己在采访中所说,「在颠覆性的技术面前,闭源形成的护城河是短暂的。即使 OpenAI 闭源,也无法阻止被别人赶超。所以我们把价值沉淀在团队上,我们的同事在这个过程中得到成长,积累很多 know-how, 形成可以创新的组织和文化,就是我们的护城河。」

2. Gemini 初期灾难性的 PR 至今依然在拖后腿。We don't get a second chance at first impressions. 时至今日大家还是言及 LLM 必提 ChatGPT 和 Claude,在开源语境下可能还会提到 Llama,当然现在得多个 DeepSeek。而 Gemini 很多时候甚至都不配出现在比较对象中…… 要知道最近几个发布比如 Gemini 2.0 Flash Thinking 的表现和成本都非常亮眼(见题图,出处 https://x.com/swyx/status/1882933368444309723)。

3. Stratechery 的解读一如既往地到位。如果没有订阅,这篇 [DeepSeek FAQ](https://stratechery.com/2025/deepseek-faq/) 是免费阅读的,推荐;如果订阅了,最近的几篇分析里对 OpenAI 的批评我认为说得很在点上。尤其关于 OpenAI (或者说 Sam 本人)对通过 regulation 巩固地位的渴望以及 o1 选择隐藏 chain of thought 的失误。

4. Reasoning 看起来潜力无限,相关从业者需要好好 reflect 自己的 research/product roadmap;而对 user 来说,一个或许有用的 tip 是从常规 model 换到 reasoning model 时,prompt 写得越像论文,得到的回答质量越好。In other words, reasoning models are not necessarily good chat models; and you might be disappointed if you use them like chat models.

小彩蛋:花了五分钟让 R1 模仿《盲视》作者 Peter Watts 的风格写的科幻小段子。

前段时间准备 ML Interview (with a focus on LLMs),浏览了不少学习资源,这里分享一些:

CMU 11-711 Advanced NLP

Language Modeling 综述。

The Transformer Blueprint: A Holistic Guide to the Transformer Neural Network Architecture

比较好的一篇 Transformer 综述。

3Blue1Brown: Attention in transformers, step-by-step

解释 Attention 最好的视频,没有之一。

Hugging Face: Mixture of Experts Explained

Hugging Face: RLHF

Hugging Face: Introduction to Deep Reinforcement Learning

Hugging Face: Multimodal Models

HF 这几个资源很适合快速查漏补缺相关的话题。

Lilian Weng: Agents

依然是最好的 Agents 综述之一。

Understanding Reasoning LLMs

一些 post-training 的细节,侧重分析了 DeepSeek R1 和 R1 Zero。

Designing Machine Learning Systems 笔记 by @tms_ur_way

适合快速查漏补缺 ML 实践中的要点。

Stable Diffusion Explained From Scratch

关于 Diffusion 基本原理的解释。



除此之外以下这几位的内容都很不错,可以针对话题有选择性地摄入。

- Andrej Karpathy 的 YouTube 视频
- Lilian Weng 的博客
- Chip Huyen 的博客

这里推荐的基本都比较入门 / high level,更多是为了查漏补缺。要深度挖掘具体话题还是得去看进一步的资源和论文等。 #ml #llm

去 Netflix campus 听了个 ClickHouse 的 meetup,他们 CTO 为了 showcase,拿 ADS-B 数据做了一个炫酷的航天器轨迹可视化网站。细节很多,包括有意思的 pattern 以及实现细节,值得一看。

Also, from Why MCP Won:
- MCP is "AI-Native" version of old idea
- MCP is an "open standard" with a big backer
- Anthropic has the best developer AI brand
- MCP based off LSP, an existing successful protocol
- MCP dogfooded with complete set of 1st party client, servers, tooling, SDKs
- MCP started with minimal base, but with frequent roadmap updates
Gemini 2.5 昨日发布。这条不是关于 model 本身,而是分享一则 HN 上相关讨论区提到的有趣数学 puzzle [1]。po 主声称 Gemini 2.5 是第一个能一次答对这道题的模型。题面见下:

There's three people in a circle. Each person has a positive integer floating above their heads, such that each person can see the other two numbers but not his own. The sum of two of the numbers is equal to the third. The first person is asked for his number, and he says that he doesn't know. The second person is asked for his number, and he says that he doesn't know. The third person is asked for his number, and he says that he doesn't know. Then, the first person is asked for his number again, and he says: 65. What is the product of the three numbers?

发现一个非常好用的 Obsidian 插件:https://github.com/RyotaUshio/obsidian-pdf-plus

通过 backlink 实现不出 Obsidian 就能给 PDF 做标注和笔记,并且笔记还可以分散在多个文件中,设计得相当 Obsidian native。
