Thanks to @AI21Labs for tracking down a silent uint32 overflow in vLLM's Mamba-1 CUDA kernel and contributing the fix. Root cause: `uint32_t` stride × cache_index overflows silently at scale. Fix merged in #35275. The debugging story is worth a read. 🔗 https://t.co/S4XBnEn1uv

MIT’s inFORM is a shape shifting interface that turns digital data into physical forms, letting users interact with objects remotely. https://t.co/ZHFjHO367n

South Korea–based WIRobotics has introduced a humanoid robot called Allex. Allex features a lightweight arm with a 15-joint hand that can sense tiny forces and lift objects up to 30 kilograms. The company plans to develop it into a safe, flexible, general-purpose humanoid by 2030.

🚨Another update to our Generative AI US adoption time series results from our paper “The Labor Market Effects of Generative Artificial Intelligence”: we find LLM adoption at work in the US fell over the past quarter (while still up substantially from a couple years ago). https://t.co/Lo1v0V2zq0

I wholeheartedly endorse this piece. It annoys the hell out of me that there's an entire cottage industry of business "journalism" that consists of taking some outlandish claim made by a tech CEO -- often in a tweet or offhand comment -- and then crafting https://t.co/gjctqdvfUU

@emollick it’s certainly not “HUGE” by conventional interpretations; in traditional psychology (Jacob Cohen’s d) .15 is small; even in the context of education I am skeptical, and see quote below from Interpreting Effect Sizes of Education Interventions Matthew A. Kraft), which would still count it as medium, not large and certainly not all caps HUGE. But th thing about effect sizes of 0.15 in my experience is that there is usually enough of a confidence interval around it that you can’t be sure how real it is. That was Cohen’s point.

Microsoft built a voice AI so powerful they had to take it down. Deepfakes. Disinformation. Too dangerous. So they added watermarks, safety controls, and re-released it. For FREE. It's called VibeVoice. Here's what it does: → Clone any voice from 10 seconds of audio → Generate 90 minutes of multi-speaker conversation in one pass → Real-time TTS, first audio in ~200ms → Speech-to-text: 60 min of audio in a single pass, with speaker labels → 50+ languages, 4 speakers, natural turn-taking ElevenLabs: $99/month. Playht: $39/month. VibeVoice: Free. Local. MIT license. 28.5K stars. Backed by Microsoft Research. The fact they had to pull it once tells you everything about how good it is.

Hate to break it to you, but the first LLM was created by Andrey Markov in 1913. he tallied up 20,000 letters from a famous novel and computed p(vowel | vowel) p(consonant | vowel) p(vowel | consonant) p(consonant | consonant) basically 'training' a bigram by hand https://t.co/M1aLF9z2ik

Forgot the obligatory action shot! 🤦‍♂️ https://t.co/lBx23Fsbq2

For the first time in 150 years of professional baseball, a human official just got publicly overruled by an algorithm. The batter takes strike three and the umpire calls the inning over but instead of walking to the dugout, the batter taps his helmet. That tap triggers a review by twelve high speed Sony cameras installed around the perimeter of the ballpark, tracking the pitch to within one sixth of an inch. The system renders a verdict in fifteen seconds, and the scoreboard shows every person in the stadium a 3D animated replay of exactly where the pitch crossed the plate. In the first week of the 2026 season, more than half of all challenges proved the umpire's call was wrong and even at their best, human umpires still missed roughly eleven calls per game. Veteran umpire C.B. Bucknor, who has worked in this league for decades had multiple calls reversed by the system in a single game. The technology itself originated in a British military lab tracking fighter jets in NATO training exercises, then became the Hawk-Eye platform Sony now deploys across tennis, soccer, cricket, and the Olympics. Tennis ran this exact experiment first, and within fifteen years there were no human line judges left at Wimbledon or the US Open. Sports betting is now legal in 38 states with individual pitch outcomes tied to real-money wagers, turning every missed call into a liability in a regulated billion dollar market. This is what AI is supposed to do, not replace human judgment everywhere, but step in where the stakes are clear, the data is objective and the cost of being wrong is real.

Palantir CEO Alex Karp just named who wins the AI era. Not the people who mastered the system. The people who could never follow it. Karp: “We’re in a non-playbook world, and the playbook’s not that valuable.” For decades, the global economy ran on compliance. Read the manual. Follow the procedure. Execute like the person next to you. AI just automated the manual. If your entire value was executing the playbook, you are now losing to something that does it perfectly, instantly, and for free. Karp understood this before most people had the vocabulary for it. Karp: “If you’re a dyslexic, you can’t follow the playbook, so you invent new and generative things.” Neurodivergent people spent their entire lives inside a system built for a brain they do not have. The front door was locked. So they found other doors. Built new ones. Attacked problems from angles nobody else tried because the standard path was never theirs. That is not a disadvantage. That is decades of forced preparation for the exact world we just entered. The front door is now locked for everyone. The people who spent their lives perfecting the rules are scrambling. The people who spent their lives ignoring them already know how to move. The system spent a century punishing the exact people it needed most. It measured compliance and called it intelligence. It filtered out the builders. The ones who could not sit still. The ones who could not memorize a curriculum designed for someone else’s mind. And called them broken. They were not broken. They were just early.

Computer use is now in Claude Code. Claude can open your apps, click through your UI, and test what it built, right from the CLI. Now in research preview on Pro and Max plans. https://t.co/s2FDQaDmr1

Claude Code on terminal: 868 mb~  Codex desktop app: 638 mb~ It's crazy how Codex desktop app uses less memory than running Claude Code on a terminal on Zed. I tested this on my Macbook Pro M4. I'm not using the agent panel on Zed, it's only Zed's terminal, which is using Alacritty. Both Claude and Codex are working on one task, simply calling read and write tools, and they are not running tasks or subagents. Also I noticed Claude Code memory usage can spike up to 1 GB+ and Codex's usage is way more consistent. Any explanation?

How can we autonomously improve LLM harnesses on problems humans are actively working on? Doing so requires solving a hard, long-horizon credit-assignment problem over all prior code, traces, and scores. Announcing Meta-Harness: a method for optimizing harnesses end-to-end

We made Muon run up to 2x faster for free! Introducing Gram Newton-Schulz: a mathematically equivalent but computationally faster Newton-Schulz algorithm for polar decomposition. Gram Newton-Schulz rewrites Newton-Schulz such that instead of iterating on the expensive rectangular X matrix, we iterate on the small, square, symmetric XX^T Gram matrix to reduce FLOPs. This allows us to make more use of fast symmetric GEMM kernels on Hopper and Blackwell, halving the FLOPs of each of those GEMMs. Gram Newton-Schulz is a drop-in replacement of Newton-Schulz for your Muon use case: we see validation perplexity preserved within 0.01, and share our (long!) journey stabilizing this algorithm and ensuring that training quality is preserved above all else. This was a super fun project with @noahamsel, @berlinchen, and @tri_dao that spanned theory, numerical analysis, and ML systems! Blog and codebase linked below 🧵

We cooked up Gram Newton-Schulz: a drop-in replacement of Muon’s Newton-Schulz that is up to 2x faster. Building this requires synthesizing ideas from linear algebra, numerical analysis, and kernel design. This makes for a great story and an even better optimizer!
