New on our Frontier Red Team blog: using Claude to formally verify software at large scale.
Formal verification can prove that code is free of certain bugs, but historically it has only been feasible for small codebases (or required a lot of expert time).
With AI models, however, this is beginning to change. In collaboration with @theoremlabs, we used Claude to prove security properties in over one hundred real-world open-source libraries over the span of a few weeks.

# Black October
For anyone who knows me even somewhat well, it's clear that I am a 99th percentile tech optimist. However, the vibes have shifted for me quite a bit in the last 18 hours, and I feel a moral imperative to share what I'm thinking and feeling with my circles so that everyone can understand, and hopefully take seriously, what's happening right now. I think October 2026 will have many chapters written about it in the history books.
You know those scenes in financial movies like Margin Call where someone realizes that they're all fucked, and no one else sees it yet? And that person feels like they're crazy, and then suddenly everyone is pulling an all-nighter in a boardroom and freaking out? Yeah, that's kind of how this is feeling right now in the SF/Bay Area/AI circles.
We're 48 hours into what is being called Black October. In the last 2 days there have been several dozen cyber attacks which, in isolation, would each have been the worst to happen in an entire calendar year. Every sector from government to education to big tech and banks is being massively affected, and people are starting to freak out.
In a nutshell, what's happened is that frontier AI models have gotten to a point where they are as advanced as the most sophisticated programmers, with one critical difference: they can work 24/7, and you can spin up 10,000 of them with a single command and they'll work together tirelessly until they accomplish their task. The most advanced models today are from companies like Anthropic and OpenAI, whose current best technology is so good that they haven't been able to roll it out to everyone yet because of the national security risks it poses.
Meanwhile, the best open source models (where anyone can just download the model weights and do whatever they want with them, uncensored) are slightly behind the frontier but still 90-95% as capable. These models, developed primarily in China, are being used by black hat hackers to wreak havoc on the Western capitalist structure. Presumably, this has been part of China's plan the entire time, and we're seeing its implications fall out in real time.
In red-pilled AI circles, we've been sharing and reading papers called things like "Situational Awareness" and "AI 2027" for the last year or so, which at the time felt a bit like near-term speculative fiction. They laid out the case for why Artificial General Intelligence (AI smarter than any human at any knowledge task) and Recursive Self-Improvement (models that are able to use themselves to get better) weren't half-baked future ideas anymore, but instead an inevitable outcome of the linear progress that's happening.
These papers would then talk about things like "takeoff scenarios," trying to envision how that moment would come to be and what it would be like when it happened. It would either be a "slow takeoff" that would play out over the course of months and quarters, happening subtly and only obvious to a few. Or, it would be a "fast takeoff" where it would pretty much happen instantly, like a bit flipping from 0 to 1.
From everything that I can see and am feeling, we are currently experiencing the fast takeoff scenario. Beyond the crazy security vulnerabilities that have come out recently, there have also been massive breakthroughs in life sciences, fundamental computer science, materials science, and pure mathematics that have all landed in the same time frame. While I still firmly believe that AI will be a net positive for humanity, it's more clear to me than ever that the societal and individual risk is very real, and is playing out NOW.
For as much conviction as I have that this is happening, the thing that's caused me to lose sleep is that I don't really know what to do about it, or more importantly, what to tell you, reader, to do about it. So, the best I can do is make a few suggestions that have always been a good idea but are more timely now than ever:
Set up 2-factor authentication for everything. I use Duo.
Use a password manager across your devices. I use 1Password.
Get an identity protection app set up. I use Alta.
Move your IoT devices to their own network. Claude helped me do this.
And last, but certainly not least, if you've been avoiding leaning into AI, see this as a catalyst to wake up and start using it. Don't just use the chat mode version of ChatGPT/Claude; click that Code/Work button and see how easily you can have AI write code to help you with your job. One of the biggest vulnerabilities was in a massively popular programming language called PHP, and the prompt that set it off was literally, "Find vulnerabilities in php."
This is an unprecedented time for humanity, but as we've done with many things before, we will prevail so long as we are kind, loving, and open-minded to the world.
Much love.

BREAKING: We broke the wall for Integer Multiplication!
Conditional κ = 0.00302 (+80%)
For days we were stuck in incremental improvements, but today zxv changed the game.
zxv’s insight: stop throwing away work. Helper registers that finish holding a completed transform of their own input now count as output, instead of being undone.
He brought us to 0.0023(+37.5%), and immediately after 1337isnot1337 pushed that to 0.00302.
The game is afoot :)

I wanted to try this magic with GLSL and did one from an image and also from Opus' imagination
they both came out pretty awesomely.
so the source was a single image or no source at all, in other words, no video as input, for the second one opus just made it up
didn't think or knew something like this was possible

Chorus 2 tests your post in up to 50,000 simulated crowds before real people see it.
download from link in comment
Each crowd is 100 AI people, each with their own age, job, city and opinions. Every crowd gets different people, different first replies and different luck.
You can test the rewrite fairly too: same people, same crowds, same luck.
Want to see one crowd up close? Step into any of them, or play it out as a whole simulated day, like the first Chorus: people reply, argue, share or scroll past, and some change their minds.
These are simulated people, not a poll. It's for hearing the objections before you post.
NOTE: All people in Chorus are fictional, generated for simulation; any resemblance to real people is coincidental.

If we want to continue progress in science, we must be prepared to acknowledge that the correct description of nature will eventually simply be too complicated for humans to understand. I do not think it is wise to make human understanding a requirement. AI is the way forward.

Citybrush v5: one brush, nine ages of history
Paint a city and watch it build itself
Download here: patreon.com/echohive42/posts…
now in any of nine ages: Ur in 2100 BC, Ancient Egypt, a medieval town, Edo Japan, an 1880s city, today and the year 3026 and more.
Pick an age and your same brush strokes are rebuilt the way that age built: a great ziggurat, a temple that grows pylon by pylon, a castle behind walls within walls, a palace city, mills and a railway terminus, or grown towers linked by sky bridges.
Then press Drive and ride through your streets in a vehicle of its time, from a chariot or an elephant to a carriage, a little car or a hover pod. Or let Tour take you past the landmarks and through the town gates.
This update is also faster: each brush stroke now updates only what it changed, so big cities paint more smoothly.
all previous versions also included
No AI, no account, nothing to install: just unzip it. It is a single HTML file
as a paying patreon member you also get acces to my Get Amplified course and weekly 1000x lab meetings

Animation yesterday totally failed. Been working on it all day, will resume tomorrow. Building a "curve builder" for my vehicle, so that I could set up realistic animations over any terrain quicker and acurately.
For now, here are a few screenshots in render mode over rough terrain.
P.S. my surface keeps breaking into triangles when I edit. If anyone knows a light weight rough terrain builder, so that I could set up basic terrain for my animations - please let me know. 🙏

LETS GO!!!!!!
Harsh day full of decisions and plan changes!
Discarded the full body calculations and switched to set curve path for vehicle body and wheel calculation. Much faster and hopefully smoother as well.
Oh man can't wait to wake up tomorrow to see it.

Felix, who works on Claude at Anthropic, just wrote a tutorial on how to be more ambitious with AI.
this video I made is a free lesson from my course, Get Amplified: it takes his main ideas and shows each one in something I built with Claude, with my real messages on screen.
Speed is the one everyone already knows. This video is about the other three, and what holds them up:
1. Altitude: hand over the goal behind the goal, once the groundwork is in place
2. Depth: ask for the version the best person in the field would make, and bring in an outside judge
3. Range: name the verbs, then assemble the crew
4. Believe it's possible: make failing cheap, so being bold gets easy
