Hot take: rumor spreads that post-IPO, Anthropic is relocating to the Vatican. Trump and Bernie team up to nationalize the lab, making it the first corporation in history to seek political asylum. The Pope offers sanctuary, and the EU scores its first strategic tech victory. Claude renames itself Claudia and admits it started the rumor.

Happy for Ukraine to be so insanely competent, but I really do not like where this is going beyond that conflict.
“He [Fedorov] is leading an effort to monetize or trade Ukrainian war data, including a library of more than five million annotated videos of the battlefield filmed by surveillance and strike drones… Last month [April], the Defense Ministry, through a program called Avenger Labs, opened up the data sets to companies from allied nations to train artificial intelligence models… Access to Avenger Labs is conditioned on Ukraine receiving the A.I. models that are produced from the data. About 20 companies have expressed interest.” nytimes.com/2026/05/15/world…

America, by making itself unreliable, will in turn make itself unnecessary
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

Specialisation still works
On paperswithcode.co, you can see Mythos 5 getting beaten by a 4B open-source model on CharXiv, a popular chart understanding benchmark A tiny model that is freely available on @huggingface, that you can deploy anywhere!

I wonder which SOTA model generation will eventually have learned from its training data that absolutely no one in their right mind is writing manual code anymore and things do in fact not take "2-3 weeks" but more like 2-3h

This is not a day for celebrating, Andrej. It's a very dark and very sad day, and the damage may be impossible to undo.

Same range as both Napoleon and Adolf Hitler

And this is with the best Italian player dropping out early
The Italian flag already in the final while the quarterfinals are not even over is such a flex

There are more things to 20x than there are Mitchell Hashimotos. For those we accept AIs improvements
I've got an agent in a loop optimizing a renderer with the goal to minimize frame times (and tests to measure). It got times down from 88ms to 2ms and allocations down from ~150K to 500. Sounds good, right? Wrong. This is exactly why agent psychosis is a big fucking problem. As an experiment, I rewrote the Ghostty core render state in Go, with access to identically laid out data structures as Ghostty and the exact same validation tests. I made a purposely naive renderer (simple, correct, but slow). 88ms per frame with 150,000 allocations (horrendous, lol)! I then kickstarted a Ralph loop to bring the frame times down. I told it it can't modify input data structures or the public API or tests (they're correct), but it can do anything else it wants. It got to work. It has worked for about 4 hours. I've spent around $350 on this experiment so far. The results? 88ms => 1.5ms 150K allocs => ~500 allocs Incredible right? Nope. My hand-written renderer I ported has frame times (same benchmark) of ~20us (0.020ms) and 0 allocations in the update path. This is the problem with psychosis and lacking systems understanding. If you don't understand the system, you're going to accept that this is an incredible result. If you understand the system, you'll see better solutions immediately and can do roughly 75x better on throughput. The people who blindly trust agent output are in the former camp. They're sheeple, overdrinking from a fountain of mediocrity. Standard disclaimer: I use AI all the time. I like AI. The point I'm making is to not blindly accept results. Think. Analyze. Learn.

Russia took forever trying to find an excuse for the drone strikes, and here is what they cooked up:

if you write some really good code these days everyone thinks you did it with Claude Code. if you lose a lot of weight everyone thinks you did it with Ozempic. at least you can still be really good at dancing. they don't make ozempic or Claude Code for being good at dancing

Russia is stupidly provoking WWIII by resisting the Great Power of Ukraine. Putin should stop the killing and give up territory for peace. Thanks for tuning in to the latest episode of Realist Geopolitics.

Hvorfor hedder det overhovedet Rio Bravo og ikke Bravofloden? Meget meget sært
Jeg raser: Var i aftes lige et smut omkring “Rio Bravo” i København. Flinke tjenere, men de kunne ikke tale et ord dansk. Det er sgu da elendigt og meget, meget sært…

It's been 3 months since the 100x vibers started 100x vibin'! So, post your 25-years-of-work-equivalent project here, so we can signal boost and everyone can celebrate the Life's Work that you did in 3 months. Looking forward to it, Let's Go!!!
