What rebuilding AlphaGo teaches us about self-play, RL, and future of LLMs - Eric Jang

Eric Jang · ex-VP AI @ 1X · ex-Google DeepMind Robotics

Eric Jang 在 sabbatical 期间用大约 10K 美元 + Claude Code 重新实现了 AlphaGo, 在和 Dwarkesh 的对谈里把 MCTS 拆到底——为什么它不是 credit assignment、 为什么它比当下 LLM RL 优雅得多、以及 10 层网络居然能把一个看似 intractable 的搜索问题塞进一次 forward pass。后半段是用 Opus 4.6/4.7 做自动化研究的体感: 超参搜索很强,但还不会"换条路想想看"。

How to ship hardware in the AI era | Caitlin Kalinowski (Apple, Meta, OpenAI)

Caitlin Kalinowski · Hardware leader — ex-Apple (MacBook Pro/Air), ex-Meta (Quest, Rift, Orion AR), ex-OpenAI (robotics)

Caitlin Kalinowski has shipped flagship hardware at three legendary companies — the original unibody MacBook Pro and MacBook Air at Apple, the Quest / Rift / Orion AR program at Meta, and most recently OpenAI's robotics division (which she publicly resigned from over the "department of war" deal). She walks Lenny through why hardware is fundamentally different from software ("we only get to compile four or five times — ever"), the 5-layer supply-chain stack that's been outsourced over 25 years, Palmer Luckey's drones-vs-aircraft-carriers argument, the impulse equation that governs robot safety, the "memory-price meteor" coming for every physical AI startup, and the four hardware design principles she carries from Apple to Meta to OpenAI.

From Consumer Toys for Pets to War Drone — Yaroslav Azhnyuk, The Fourth Law & Noah Smith, Noahpinion

Yaroslav Azhnyuk · Noah Smith · The Fourth Law / Odd Systems — founder · Noahpinion — writer

Yaroslav Azhnyuk built Pet Cube in San Francisco — "cameras that fling treats to pets" — and then, after Russia's invasion landed on the last flight into Kyiv on Feb 23, 2022, pivoted to building drone autonomy, thermal cameras, and FPV strike drones for the Ukrainian armed forces. With Noah Smith and Latent Space's Brandon, he walks through five levels of drone autonomy, eight dimensions of the autonomous battlefield, why FPVs replaced artillery as "the god of war" (~80% of frontline casualties), and the disquieting arithmetic of China's drone manufacturing scale (4M Ukrainian FPVs/year vs ~4B Chinese capacity).

132. 对星海图创始人高继扬的3小时访谈:鲶鱼、曾国藩、Waymo与Momenta的两面、一只狼与许华哲的离开

高继扬 · 星海图创始人 & CEO

张小珺对星海图创始人高继扬的 3 小时访谈。92 年生人、清华电子系物理竞赛保送、 USC PhD 三年半毕业、Waymo 两年、Momenta 两年作为"鲶鱼"轮换感知/定位/规控/NOA、 23 年 5 月放弃 1000 万美金期权创业。访谈把具身智能创业的"反浪漫"逻辑讲透—— 从曾国藩式的"儒家清流到事功"自我重塑,到智能定义本体的轮式双臂选型, 再到 200~250 元/小时的真实数据成本账、VLM+VLA 双系统、 以及"传播周期决定壁垒"的大厂 vs 创业公司分析。访谈录制时正逢联合创始人许华哲离职。

The $15B Physical AI Company: Simulation, Autonomy OS, Neural Sim, & 1K Engineers—Applied Intuition

Qasar Younis & Peter Ludwig · Co-founders of Applied Intuition (CEO / CTO)

Applied Intuition 给汽车 / 卡车 / 矿车 / 农机 / 防务平台卖"让物理机器变聪明"的技术栈, 18/20 OEM 是它客户, 估值 $15B, 1000 名工程师, 现在在日本跑 L4 无人卡车. 这期把它的三个 bucket (仿真 + 操作系统 + 自动驾驶模型) 全部摊开讲, 还顺手把 "vehicles like pre-Android phones" 这条 类比、neural sim = Gaussian splatting + diffusion、onboard 才是物理 AI 真正瓶颈 这些反直觉点都串了起来.

134. 【数据的综述】和谢晨聊,新时代的石油、历史、版图、数据金字塔、定价与Recipe

谢晨 Steve · 光轮智能创始人 & CEO

张小珺《商业访谈录》第 134 期:和光轮智能 CEO 谢晨把 AI 的"数据"这架马车 做成一次产业综述。从数据 = 教育的第一性类比,到朱玉可提出的数据金字塔 (真机 / 仿真 / 人类第一人称视频),再到为什么特斯拉模式在具身不成立、 BEHAVIOR Challenge 的 26%、为什么"先失败再成功的数据最贵",一直到终局: 一家 AI 教育公司,提供环境让模型自己修炼内功。

Elon Musk – "In 36 months, the cheapest place to put AI will be space"

Elon Musk · CEO of Tesla, SpaceX, xAI

Elon Musk 与 Dwarkesh Patel 长达 3 小时的深度对谈,涵盖太空 AI 数据中心(36 个月内最经济)、 Starship 每小时一次发射、月球质量驱动器、Terafab 自建芯片厂、Optimus 机器人的递归指数增长、 中美制造业竞争,以及 xAI "understand the universe" 使命与 AI 安全。

The real AI revolution isn't software. It's farms, mines, and trucks. | Qasar Younis

Qasar Younis · Applied Intuition CEO

Applied Intuition CEO Qasar Younis 首次公开访谈。他认为 AI 真正的影响不在软件开发, 而在农业、矿业、建筑和卡车运输等物理行业。对谈涵盖 Physical AI 路线、 中国竞争的误读、创始人的沉默哲学、以及一家近十年未花过融资的 $15B 公司如何运营。

Moonlake: Interactive, Multimodal World Models — with Chris Manning and Fan-yun Sun

Chris Manning · Fan-yun Sun · Stanford NLP 教父 · Moonlake 联合负责人 + ex-NVIDIA Research / Moonlake co-founder

Latent Space 与 Moonlake 两位负责人 Chris Manning 与 Fan-yun Sun 的对谈。Moonlake 押的是另一条 world model 路线: 不是更大的视频生成器, 而是 symbolic 推理 + 神经渲染。 Chris 给出唯一的硬定义 — "you only actually have a world model if you can predict, given some action is taken, what is going to change" — 然后顺势公开和 Yann LeCun 撕: "Yann has never appreciated the power of language." Sun 反驳"反 bitter lesson" 的标签, 真正的问题是"what is the right abstraction level today"。Moonlake 内部其实是 两个模型: 推理模型管 causality / persistency, 而 Rie 这个 diffusion model 负责 photorealism — 他们已经把它当作 DLSS 的下一代来卖, "skins for worlds"。
