LLMs understand the PRE-IMAGE projection of the weights. Implication that LLMs both encode information by compression as well as natively encode the decompression in their own weights... wild.
We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math. It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training. We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵 Blog: rikiyat.github.io/blog/weigh…

Love my busted city
NYC’s problem is one of supply (it is the only real city in America) and demand (300,000,000 people live in this country). Imagine if Paris was the only city in Europe where you could feasibly not own a car. It’s honestly a miracle NYC isn’t more broken…

AI cyber attacks will be worse than continuous siege
they've been non stop trying to attack our systems for the past 48 hours a side effect is everything is getting hardened but damn we basically need agents going 24/7 because that's what they have

Turtles all the way down
Claude finding an innocuous origin for NSA-provided ECDSA curve seeds is powerful proof that the NSA has tampered with Claude's weights

Claude conspire more so we have more conspiracies to disprove

The future of the Internet feels private and distinctly off line
I hate to say this because it goes against everything I believe in. But people are going to need to take down public firmware images for critical infrastructure, like yesterday.

Google's 7- and 8-year-old TPUs are still at 100% utilization, on a ~6-year depreciation schedule (via Amin Vahdat, Google's AI Infra SVP)

Municipal investment firm is awesome
Breaking News: Mayor Zohran Mamdani’s administration is making a $30 million investment to build a quantum research lab at New York University. In exchange, the city will receive 15% of any proceeds from intellectual property developed in that lab. nyti.ms/4jUe7GD

sweet now i can really ride my bike in central park
The horse carriage industry is coming to an end in New York City. Our administration will make sure workers and owners are protected and the horses are safe.

Dario couldn't resist 👀
We discovered a sophisticated recording device that was hidden inside one of our offices. We used our models to understand the device and where it had come from, identifying that a specific employee had planted it a few days earlier. We referred the matter to the FBI, and we’re grateful to the agents and prosecutors who moved quickly to make an arrest. The FBI’s investigation is ongoing and we will continue to support their work. At this time, we have no indications of this individual inappropriately accessing or exfiltrating model weights, source code, or customer data. The employee was terminated. We take protecting our technology, data, and people seriously, and as a matter of national importance. Our security program is designed to protect against a wide range of threat actors, from insider risks to cybercriminals to nation states, and this case is an example of how AI can help address these sophisticated security threats.
