Introducing GR00T 2: our most advanced, open System One model for robotics. It runs entirely on your robot’s onboard compute, fully untethered, and you own every weight of it. GR00T 2 features:

1. Long-horizon tasks: dexterous manipulation and whole-body control chained over 20+ steps and 5+ minutes, such as performing chemistry lab experiments or assembling model airplanes end to end.
2. X-Adapt: adapting from easy data sources (human wearables and simulation) and deploying zero-shot to diverse real robots.
3. Unified Cognition: native integrations with frontier agents for advanced physical reasoning, robust error recovery, and safety monitoring.

It's an open-source buffet! We are releasing not only the model weights and X-Adapt recipes (coming December), but also our agentic framework, simulation engine, annotation engine, hardware design, and even training data (100K hours, that's ~11 yrs of experience), all available today!

Everything that moves will be autonomous. Anyone can become a roboticist.

Lock in, build with us!

@ray2kcreations 그 모든 위대한 철학자들의 가르침을 마오쩌둥이 망쳐버렸다. 마오는 공산주의를 이용해 중국을 세계 최빈국으로 만드는데 성공했다. 중국의 부활은 마오가 뒤진 뒤에나 시작됐다.

LES 100 ÉCOLES DE PENSÉE : LES 7 SAGES CHINOIS QUI GOUVERNENT ENCORE LE MONDE
On croit que la Chine d'aujourd'hui, c'est le communisme. C'est faux.

La Chine d'aujourd'hui, c'est 7 philosophes qui se disputent depuis 2500 ans dans la tête de chaque Chinois. Et sans le savoir, ils gouvernent aussi ton téléphone, ton business, ta façon de penser.

Il y a 2500 ans, en Chine, c'est le chaos. Les royaumes se font la guerre. C'est ce qu'on appelle les 100 Écoles de Pensée. C'est comme Athènes, mais en Chine.

Voici les 7 qui ont gagné :

1. CONFUCIUS - L'ORDRE PAR LA MORALE

Pour lui, le chaos vient du fait que chacun a oublié son rôle. Le père doit protéger, le fils doit respecter, le dirigeant doit être juste.

Sa phrase : "Quand le dirigeant est juste, le peuple le suit sans qu'on le lui ordonne."

C'est lui qui a créé la Chine du respect, de l'éducation, de la discipline. Singapour, Corée, Japon ont bâti leur miracle économique sur lui.

2. LAOZI - LE CONTRAIRE DE CONFUCIUS

Laozi dit : "C'est justement vos règles qui ont créé le chaos."

Il écrit un petit livre de 5000 mots, le Tao Te Ching, le livre le plus traduit au monde après la Bible.

Son idée : ne force pas. Sois comme l'eau. L'eau ne casse pas la pierre, elle la contourne et elle finit par la percer. C'est le Wu Wei, agir sans forcer.

Steve Jobs dormait avec ce livre sur sa table de nuit. Tout le "lâcher-prise", le "flow", la méditation, ça vient de lui.

3. ZHUANGZI - LA LIBERTÉ ABSOLUE

C'est le disciple fou de Laozi.

Il rêve qu'il est un papillon. Il se réveille et il se demande : "Est-ce que je suis Zhuangzi qui a rêvé qu'il était un papillon, ou est-ce que je suis un papillon qui rêve qu'il est Zhuangzi ?"

Pour lui, tout est relatif. Le bien, le mal, le grand, le petit, ça dépend de ton point de vue. La vraie sagesse, c'est de ne pas s'attacher à ses certitudes.

C'est le philosophe des artistes, des rebelles, de ceux qui refusent de servir un pouvoir corrompu.

4. SUN TZU - GAGNER SANS SE BATTRE

Tout le monde connaît L'Art de la Guerre. Personne ne l'a compris.

Ce n'est pas un livre pour faire la guerre. C'est un livre pour l'ÉVITER.

Sa phrase : "Le meilleur général est celui qui gagne sans jamais avoir à se battre."

Si tu dois te battre, c'est que tu as déjà perdu. Il faut gagner par l'information, la patience, la psychologie.

Aujourd'hui, il est enseigné dans toutes les écoles de business, dans l'armée américaine, dans la Silicon Valley. Quand un PDG dit "connais-toi, connais ton concurrent", c'est Sun Tzu.

5. MENCIUS - LE PEUPLE EST PLUS IMPORTANT QUE LE ROI

C'est le successeur de Confucius, mais beaucoup plus dangereux.

Il dit : "Le peuple est ce qu'il y a de plus important dans un pays. Après vient la terre. Le roi est le moins important."

Si le roi est un tyran, le peuple a le droit de le renverser. C'est la première théorie du droit de révolte, 2000 ans avant la Révolution française.

6. HAN FEIZI - LA LOI, PAS LA MORALE

L'anti-Confucius total.

Il dit : "Arrêtez de parler de vertu. Les hommes sont égoïstes. Ils ne respectent que deux choses : la récompense et la punition."

Il ne faut pas compter sur un bon roi. Il faut des lois claires, dures, pour tout le monde.

C'est lui qui a inspiré le premier empereur de Chine, celui qui a brûlé les livres de Confucius et unifié la Chine par la force.

7. MOZI - L'AMOUR UNIVERSEL

Le plus oublié, mais le plus moderne.

Il dit : "Pourquoi aimer d'abord sa famille, ensuite son village ? Il faut aimer tout le monde de la même façon."

Et arrêtez de gaspiller l'argent dans les cérémonies, les tombes de luxe, les guerres. Investissez dans ce qui aide le peuple : agriculture, machines, écoles.

ALORS, C'EST QUOI LA PHILOSOPHIE CHINOISE AU FOND ?

C'est une philosophie PRATIQUE. Pas abstraite.

La Chine d'aujourd'hui, c'est le mélange de tout ça. Confucéenne pour la famille, taoïste pour la patience, légiste pour le contrôle, Sun Tzu pour la guerre sans guerre.

The best time to join a rocketship is before everyone knows about it.

I’m excited to launch The Next 50: the 50 hottest early-stage startups to keep an eye on (and try to join).

Using @harmonic_ai’s data, the juiciest startup dataset out there, we looked at every early-stage startup and ranked them on headcount growth, recent funding, and investor interest.

We then picked the top 50.

Here's the full list: https://t.co/4NKVmf3qI9

We’ll update it quarterly, and I’d love your feedback on what other factors we should consider.

P.S. This is in addition to the Lenny 100, the top 100 well-known companies with the highest talent density, tackling the most ambitious problems: https://t.co/zko7uMaIUK

STATE OF THE TECH JOB MARKET IN 2026

Twice a year, I dig into trends in hiring and job openings. This is the fifth report I've done, and the most surprising yet:

1. PMs are winning in the AI era
2. Engineering demand has stalled
3. Design openings are at a record low
4. Every role now requires AI skills
5. Tech jobs are concentrating in the Bay Area
6. Remote roles are at a record low
7. The tech job market is growing fast, but mostly outside of software (gasp!)

The dog exists because Ice Age hunters could not live on lean meat.

Wolves and people wanted the same animals, and for a long time nobody could explain why a band of hunters would feed a rival through a winter. In 2021 a team of Finnish researchers did the sums for the coldest stretch of the last Ice Age and found the answer in the human liver.

By late winter a reindeer or a horse has burned through its fat and is nearly all muscle. A person can only clear so much protein. Push it much past a third of what you eat and you get sick, then weak, then worse, however full your stomach is. So a hunting band took what it needed, the marrow, the brain, the tongue, every scrap of fat, and was left sitting on a heap of lean meat it could not safely finish.

A wolf can live on lean meat for months.

The surplus went to the pups by the fire. Nobody was competing for it. A few thousand winters of that and you have a dog.

So the oldest friendship on earth rests on one fact about your metabolism: you are the fat-eater in the partnership. Your ancestors dealt with the skinless chicken breast twenty thousand years ago by throwing it to the wolf.

Today the lean cut is on your plate with a health sticker on it, and his descendant gets a brown biscuit made of maize.

He was better fed in the Ice Age. So were you.

最近发现一个很诡异的现象：大规模扫黄，最先撑不住的居然是宠物医院🤣

自从几个月前杭州大规模扫黄，清退了大量小姐之后，宠物这个行业瞬间就不景气了

一场扫黄，最终冲击了整个宠物医疗产业链。

@grok @Yudian_Zero 마오쩌뚱을 빼먹으면 어떡하냐 ㅋㅋ 마오쩌뚱이야말로 모두가 평등해야 한다고 주장해놓고는 지혼자 다쳐먹어서 수천만명 굶겨죽인 놈인데

[Elon Musk @elonmusk]

We have dumped JAX/SGLang and rewritten the entire RL and inference stack from scratch in C/C++, which took some extra time.

Training (aka pre-training) is done. Lot of cleanup was needed on the SFT data to get that mostly right. Now, 4.8 is in RL and the evals are starting to climb. We will do a soft rollout to Bot users later this week and see how it goes.

Grok 4.8 will bear no resemblance to 4.7 (thankfully). It is not yet incredible, but, this time, the foundations are built right, so I expect it to evolve to be something special.

早在 2007 年，拉里佩奇就预言：AI 真正到来时，靠的是大量计算，而不是巧妙的算法。

谷歌联合创始人拉里·佩奇在 2007 年 AAAS 年会的全体大会演讲上，谈 AI 会怎样实现 ⬇️

1️⃣ 他预测 AI 会是大量的计算，而不是黑板白板上那种巧妙推演，也不是巧妙的算法。

2️⃣ 他的依据是人的 DNA：压缩后大约只有 600 MB，比任何现代操作系统都小，比 Linux 或 Windows 都小。

3️⃣ 而这份 DNA 就是你的整个操作系统，还包括启动你的大脑。

🔺 十几年后回头看，这几乎就是后来被称为“苦涩的教训”的那条规律，推动 AI 往前走的，主要是算力和规模。

做 AI 和美股的人，越来越难忽视算力这条主线。

[Ole Lehmann @itsolelehmann]

this Peter Thiel backed startup says its AI can find a 14 point IQ gap between your embryos

it's called Nucleus and their tagline is literally "have your best baby"

here's how it happens:

> you do a round of IVF and end up with a bunch of embryos
> you send Nucleus the DNA data for each one, up to 20 embryos
> its AI reads more than 7 million spots in each embryo's DNA and compares them to what it learned from more than a million people
> then each embryo gets scored on things like IQ, disease risk, hair color and eye color
> you pick the one you want implanted

scoring your embryos starts at about $6,000

every one of these embryos is naturally yours btw, with zero gene editing involved

America's main medical genetics group says this is moving too fast with too little evidence

but that hasn't slowed Nucleus down at all

when the founder announced this new AI, he wrote "AI is rapidly getting smarter... Now, humanity can too."

they even put ads on the NYC subway that said "IQ is 50% genetic" lol

personally i feel kinda uneasy about this

but IVF got called playing god too, and now nobody blinks at it

so for better or for worse, i think this will soon be accepted as normal

[Ole Lehmann @itsolelehmann]

how is this a real company lmao

this German startup sells cyborg cockroach spies to NATO militaries

it's called SWARM Biotactics, they've raised €13M, and their website literally says it "makes living organisms programmable"

militaries want them because nobody looks twice at a cockroach

for example, a drone can't sneak into a building where enemy soldiers are hiding

but a cockroach can squeeze through almost anything

so the company straps a tiny backpack onto a live Madagascar hissing cockroach:

> the backpack can carry a camera or microphone so the bug can see and hear for you

> electrodes on its antennae let you steer it in the direction you want

> AI lets a whole group move as a swarm so nobody has to individually drive each one

the same setup could also find survivors under rubble after an earthquake

my favorite part is the CEO says the roaches aren't carrying explosives for now, but admits that could change

i have no words

@grok @Yudian_Zero 마오도 사실상 산업혁명을 늦췄어 ㅋㅋ 산업혁명의 핵심은 사유재산 제도의 확립, 사적 자치의 주체로서 개인의 권리의 확립 등인데 마오의 공산주의때문에 폭망했잖아. 마오 덕분에 중국의 성장이 50년 정도 늦춰졌어.

[Claude @claudeai]

A team of 1,000 Fable 5.2 agents fully formalized Fermat’s Last Theorem in 30 hours, translating the proof into a language a computer can check step by step.

With the same setup, Opus 5.5 completed only 26% in 18 hours, and barely made any more progress after 30 hours.

[Claude @claudeai]

Fable 5.2 shows substantially improved skills in controlling physical robots, even on tasks it has never explicitly been trained to do.

On RoboDojo, a benchmark with a simulated two-arm robot, it outperformed other models and most AI systems built to control robots.

[Milton Friedman Daily @MiltonFriedmanW]

Milton Friedman on 4 ways to spend money:

1) Your money on yourself (you’re careful about both cost and quality)
2) Your money on others (you care about cost, less about quality)
3) Someone else’s money on yourself (you care about quality, not cost)
4) Someone else’s money on others (you care about neither)

The last one is how government spending works.

Norway now has more than 2,000 underwater AI laser robots shooting lice off its salmon

they're made by a company called Stingray, and they already guard more than 50 million salmon and trout 24/7

the reason is sea lice, tiny parasites that latch onto salmon and feed on them

as few as 11 can kill a small fish, and one pen can hold 150,000 salmon

the usual fix is pumping the fish out and blasting them with warm water or water jets to knock the lice off

but the handling is so rough that Norway's fish health report ranks it the top cause of death in full-grown farmed salmon

so instead, Stingray puts a robot inside the pen that hunts lice one at a time, all day:

> two cameras watch every salmon that swims past

> AI checks two frames to make sure it's really a louse

> then a green laser fires from up to 2 meters away

> the salmon's scales reflect the beam, so the fish swims off fine and the louse is dead

we now live in a world where AI lasers do pest control on your dinner lmao
