Anthropic leaked 512,000 lines of Claude Code source code yesterday.
What happened in the next 12 hours is absolutely wild.
4 AM. Anthropic pushes an update to npm. Inside the package: their entire codebase. A 60 MB debugging file accidentally bundled in.
23 minutes later, researcher Chaofan Shou spots it. Downloads the zip.
Posts it on X. Within 6 hours: 3 million views.
By the time Anthropic’s team woke up, the code was forked 41,000+ times across GitHub. Anthropic started firing DMCA takedowns. Too late.
A Korean developer named Sigrid Jin woke up to his phone exploding. He’s Claude Code’s biggest power user.
WSJ reported he burned through 25 billion tokens last year.
He read the leaked code.
Rewrote the entire thing in Python in 8 hours. His repo hit 30,000 stars faster than any GitHub project in history.
Then he rewrote it again in Rust. That version now has 49,000 stars.
Someone mirrored it to a decentralized platform with one message: “will never be taken down.” The code is permanent. Anthropic cannot get it back.
Here’s the part I can’t stop thinking about: Anthropic built something called “Undercover Mode.” Its only job: prevent Claude from accidentally leaking internal secrets.
They shipped an entire anti-leak system in their own product. Then leaked their own source code in a .map file. Irony is beautiful
The man who INVENTED modern AI just made a billion dollar bet that ChatGPT, Claude, and every AI company on earth is building the wrong technology.
Yann LeCun won the Turing Award in 2018 for creating the neural networks that made AI possible.
He spent a decade running AI research at Meta. Oversaw the creation of Llama and PyTorch, the tools that half the AI industry runs on.
Then he quit.
And raised $1.03 billion in a seed round.
The LARGEST seed round in European history. $3.5 billion valuation before generating a single dollar of revenue.
Bezos wrote the check. So did Nvidia. Samsung. Toyota. Temasek. Eric Schmidt. Mark Cuban. Tim Berners-Lee (the guy who invented the internet).
His new company is called AMI Labs. And it's built on one thesis:
Every AI company spending billions on large language models is wasting their money.
ChatGPT, Claude, Gemini, Grok. They all work the same way. They predict the next word in a sequence. See "the cat sat on the" and predict "mat." Scale that to trillions of words and you get something that sounds intelligent.
But LeCun says it doesn't UNDERSTAND anything.
It can't reason. It can't plan. It can't predict what happens when you push a glass off a table. A two year old can do that. GPT-5 cannot.
That's why AI hallucinates. It doesn't have a model of how the world actually works. It just predicts words.
His solution? Something called JEPA.
Instead of predicting words, it learns how the PHYSICAL WORLD works. Abstract representations of reality. Not language but physics.
Think about what that means.
Current AI can write your emails. LeCun's AI could design a car, run a factory, operate a robot, or diagnose a patient without hallucinating and killing someone.
The CEO of AMI said it perfectly: "Factories, hospitals, and robots need AI that grasps reality. Predicting tokens doesn't cut it."
And here's what's really crazy to me...
LeCun isn't some outsider throwing rocks. He literally built the foundations that ChatGPT runs on. He knows exactly how these systems work because he helped create them.
And after watching the entire industry sprint in one direction for three years, he raised a billion dollars to run the OPPOSITE way.
No product. No revenue. No timeline. Just pure research. He told investors it could take YEARS to produce anything commercial.
But they funded it anyway in just four months.
Meanwhile OpenAI just raised $120 billion and still can't stop their models from making things up. Anthropic is building AI so dangerous they're afraid to release it. Google is burning billions trying to catch up.
And the guy who started it all says they're all solving the wrong problem.
Two Turing Award winners raised $2 billion in three weeks betting AGAINST the entire LLM approach. LeCun at AMI. Fei-Fei Li at World Labs.
The smartest people in AI are quietly building the exit from the technology everyone else is betting their future on.
Either they're wrong and the trillion dollar LLM industry keeps printing.
Or they're right and every AI company on earth just built on a foundation that's about to crack.
@adriankuleszo Hey, i’m a relatively new freelance designer/developer, i have faced it with clients, is it a good idea to have a concrete contract which protects both parties and sets limits on such requests and aggressive changes?
My dear front-end developers (and anyone who’s interested in the future of interfaces):
I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept):
Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow
