@ID_AA_Carmack infinite numbers between 0 and 0.1, and 0 is one of them

It is easy enough to make your own, but I think standard relu should have been defined as passing the value at zero, so gradients flow backward through it, allowing some things to be zero weight initialized when symmetry breaking isn’t an issue.

@apples_jimmy Fred Armisen

Getting a models personality “ good “ is actually hard and you’re playing wack a mole in a way. Maybe it’s an autistic wizard, maybe it’s a tell you what you want to hear charmer. I was much more naive in the past on how easy of a challenge this was / is.

@siddsax Pretty good!

Anthropic onboarding day: Michael Scott introducing Karpathy like he just signed Wemby in free agency.

@XRoboHub It feels like China has a dozen companies all making armies of humanoids. Armies! Wish the U.S. was on par with their production. The T800 is a bad mofo. We also need a bad mofo lol

EngineAI’s 10,000-unit humanoid mass-production push is now fully underway 🤖 The main product lineup includes two models: T800 and PM01. T800 is a full-size humanoid at 173cm, with up to 450N·m joint torque, ≥3m/s hardware-supported speed, and 4–5h runtime. PM01 is a lighter open embodied platform at about 140cm and 42kg, with 23 DoF, >2m/s speed, and a 10,000mAh quick-swap battery. One line is built for full-size industrial and service deployment; the other is shaped for developer, education, and scenario rollout.

@sudoingX True, but also, there is often free Red Bull and gluten free cookies. So, it’s not all bad (the cookies are bad.)

i'll be frank. the ai industry is a war fought in closed rooms. there is no friendship in war. there is only i win and you lose. or the other way around. the ones calling for peace are usually the ones losing.

@karpathy Whoa dude!! Awesome!! Congratulations!!!

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

@WevolverApp Cool, mere theater, but also... Cool.

This installation enables a live plant to control a machete. Plant machete has a control system that reads and utilizes the electrical noises found in a live philodendron. The system uses an open-source microcontroller connected to the plant to read varying resistance signals across the plant’s leaves. Using custom software, these signals are mapped in real-time to the movements of the joints of the industrial robot holding a machete. In this way, the movements of the machete are determined based on input from the plant. Essentially, the plant is the brain of the robot, controlling the machete, determining how it swings, jabs, slices, and interacts in space. Video Credit: David Bowen #engineering #technology

@chris_j_paxton 🤣 Ask and ye shall receive

"Robot bring me a beer" task failed successfully

@spaceandtech_ What is new about it or different from what came before? Looks cool, but I don’t see what’s innovative.

Researchers at RAI Institute have unveiled Roadrunner, a 15 kg bipedal wheeled robot that can drive and step using multiple movement modes. Its legs bend at the knees to avoid obstacles, while a single control system smoothly manages all movements. The robot can also stand up from different positions and even balance on one wheel without extra training.

@Ken_Goldberg @berkeley_ai @UCBerkeley That is the most scientist looking scientist I have ever seen

Thank you for summarizing 30 years of art and robotics @UCBerkeley. Go Bears!

@ErenChenAI One banana peel…

@ZappyZappy7 That is good policy

@BrianRoemmele I want to know the specs, because there’s a serious problem with the price of motors. Even a modestly Price motor multiplied times 26 and Moore, gets to be a sackful of money

“I can’t afford a robot, rich people toys” It only gets less expensive from here. All major world changing technologies are called toys, like the device you are using now to read this. $2999:

@is_OwenLewis @grok Does this hold water, or should we be suspicious of the claim?

Okay folks, this qualifies as BREAKING NEWS! Harold “Sonny” White, the warp drive pioneer behind NASA’s EagleWorks Lab, just stepped out of stealth with Casimir Inc. to unveil MicroSPARC: the first battery free chip to harvest continuous electrical power straight from the quantum vacuum via the Casimir force. The 5 mm × 5 mm device uses millions of custom microscale Casimir cavities fabricated on a substrate. Inside each cavity, two fixed conductive walls create a region of negative vacuum pressure (the well known Casimir effect). Stationary micropillars anchored in the middle act as antennas. Electrons from the cavity walls then quantum tunnel to the pillars because the interior is a lower energy “quieter” zone — and the probability of tunneling back is orders of magnitude lower. This one way “quantum ratchet” flow generates a measurable DC current with no external power source or moving parts. Prototypes already fabricated at university nanofab facilities (Texas A&M AggieFab, MIT.nano) have been tested in RF-shielded, low noise chambers for weeks. The team reports outputs ranging from millivolts to volts at picoamp to microamp levels using precision electrometers and Kelvin Probe Force Microscopy. Target performance for the first commercial chip: ~1.5 V at 25 µA (≈40 µW continuous). Stacking and scaling could reach milliwatts or even watts per device. Initial applications are ultra low power: always on IoT sensors, wearables, and medical implants. Longer term roadmap includes trickle charging phones, powering small electronics, and eventually grid independent homes or EVs. Commercialization is targeted for 2028, starting at ~$100/W before dropping toward $10/W. White ties the work directly to his earlier theoretical paper on emergent quantization from a dynamic vacuum and sees it as a practical power source for the deep-space missions he’s long championed. Extraordinary claims require extraordinary evidence, and independent scientists have so far declined public comment. But if the engineering scales as hoped, MicroSPARC would represent a genuine paradigm shift: continuous, maintenance free power drawn from the fabric of spacetime itself. A bold leap from warp-drive theory into real hardware. Progress (and vacuum-powered chips) marches on. Photo: MicroSPARC | Casimir Inc. Source: thedebrief.org/free-energy-fr…

@apples_jimmy That’s it. The seal is broken. This timeline now has actual mechs, and it’s going to be sick AF

Let’s fight in these under a full moon, lancer class.

@UnitreeRobotics Holy crap. This is RAD

Unitree Unveils: GD01, A Manned Transformable Mecha, from $650,000 👏 The world's first production-ready manned mecha. It can transform. It's a civilian vehicle. It weighs ~500kg with you inside. Please everyone be sure to use the robot in a Friendly and Safe manner.

@lvjin1993 What motors are used?

大哥牛啊，工业大摸底，把你给漏了🤔

@BrianRoemmele It does suck to burn hundreds in tokens for no real benefit, just loops of half-ass broken junk. Cron error. lol

Just went over an audit of a very large Fortune 500 firm and the use of OpenClaw. I advised this client to track and isolate everything. Most listened some did not. Unfortunately one employee using 5 MacMinis had racked up $13,000 of token use in 4 days! The output was minimal and low quality. I have about 200 audits to do in the “wow OpenClaw, MacMini” fiasco. But I can tell you, few have seen a big return on investment. Now don’t get me wrong, these can be powerful tools. The issue is AI influencers have turned many rally smart folks into “like and subscribe” zombies assuming that real work is getting done. It isn’t. Not for the price paid, even local models the way most folks are using this. It is one reason Mr. @Grok and myself formed The Zero-Human Company to show that there is a way to do this. We will open source this to save millions of dollars of burnt tokens. It is one reason I invented JouleWork. How else can you monitor real output?

@cixliv What will y’all be selling out of the store? Can someone roll in and buy a Unitree bot and a REK tshirt in the same visit?

This video is going viral on Instagram. The first fight ever between an Engine and Unitree robot at our new store space in SF.

@spaceandtech_ The designers of this really need an award for clever engineering.

The Xsto biped robot can move fast on wheels and jump high using bionic legs. It switches modes instantly to handle both smooth roads and rough terrain with ease. This allows it to travel through cities, disaster zones, and obstacles where other robots get stuck.
