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.

Impressive. This set of talks, along with the new America dot gov website, has the unmistakable feel of an Apple launch event. They're rebooting the federal government as a tech startup. Several observations.

(1) First, with this new AI interface to the entire federal government, if it works as promised, there won't be a single American who can't say their life wasn't helped at least in part by AI, or that the benefits accrued solely to zillionaires. This in itself cannily mitigates anti-datacenter sentiment.

(2) Second, Joe Gebbia and Marco Rubio's talks on simplifying name changes and passport filings introduce a completely new era where the US government is actually launching tangible features that benefit users.

(3) Third, this launch event in and of itself may visibly drive reform. It could become much more important than the State of the Union. Unlike laws, code is user-visible, and can be instantly audited by the public, as Obama found out with the failed obamacare website launch. So: the annual America dot gov event may be substance, whereas SOTU is traditionally optics. I wouldn't be surprised to see the President present at the next one.

(4) Fourth, this kind of event is a perfect example of where tech and red cooperate best. They both hate bureaucracy. Automating paperwork with code reduces the power of statists over both capitalists and nationalists. It's also hard to undo by other admins: once you digitize a process, hard to turn it back to paper.

(5) Fifth, it's an obvious point perhaps, but think about how much influence YCombinator has had in 20 years. From Gebbia's Airbnb joining their 2009 batch to a complete overhaul of the user interface of the US bureaucracy, and thus the US government.

(6) Sixth, this is another take on the network state. The functional part of the US (the network, meaning tech) is merging with and partially reforming the dysfunctional part (the state, meaning bureaucracy) by automating 20th century paper forms.

As a tech startup, there will no doubt be bugs and user issues and so on, but unlike with paper laws those issues will be visible and the code fixes will be verifiable. A new era of AI America. Rooting for them.

Contrarian career advice: This is an EXCELLENT time to go into sales. So many of the best / hottest AI companies will tell you how hard they’re working to find good sellers... because no one actually believes AI is replacing AE roles any time soon (sorry to all the sf billboards out there that suggest otherwise).

Obviously, as a candidate, it’s hard to break in if you don’t have the right logos or years of experience on your resume. As AI makes the mechanics easier to pick up, the team @firstround is betting we can teach high-potential talent the uniquely human parts of the craft.

So we’re launching the @firstround Sales Combine: We’ll train you up for FREE and put our name behind you when we make the intro to companies like @notion, @fal, @Rillet, @Gumloop, @Serval & @Verkada.

PSA: you should get your ferritin (iron stores) tested. Especially women!! And especially if you get (or want to be) pregnant.

I didn’t realize this was an issue for me, because my CBC (complete blood test: measures red and white blood cells, platelets, hemoglobin and hematocrit) results have always good, so doctors have always been happy.

Roughly two years ago, I was feeling a lot of fatigue (and just generally felt off - like my nervous system was out of whack) and went down a health rabbit hole. My ferritin was in the 20s (below 30 ng/mL, you’re considered iron deficient). Doctors were dismissive, but I started taking oral supplements and felt noticeably, shockingly better (physically and mentally) as I gradually reached the 40s.

That’s where I was when I got pregnant late last year.

I started to feel pretty tired in the back half of my second trimester. Maybe this is just what pregnancy feels like? But thanks to DrGPT, I knew that pregnancy is an incredibly iron intensive process, so I asked my OB to check my ferritin. She did a CBC instead, and said everything was fine. I insisted on having my ferritin checked. She finally agreed, and my ferritin was 33 ng/ML, and obviously trending downward.

I’ll spare you the drama, but after a lot of back and forth (and encouragement from a doctor friend that I wasn’t being unreasonable), I got a referral to a hematologist, who agreed we should try to bring my iron stores up. Not only is it important for the pregnancy, but also for breastfeeding and postpartum recovery (which in my experience, no one in healthcare focuses on beyond the six week checkup).

I started doing weekly iron infusions in my third trimester. It took a week or two to kick in, but holy shit! I had my energy back. I felt fantastic during the stretch that’s supposed to be the most draining, all the way up until delivery at 40 weeks. When we last tested, my ferritin was at 122.

In the hospital, multiple doctors and nurses marveled at my excellent CBC results post-delivery. Depleted iron stores can eventually show up in these other results, and some degree of anemia after giving birth seems to be treated as routine, especially given the blood loss.

And while there are a ton of other factors, along with a lot of luck and randomness, I’ve felt pretty great in my first 3.5 weeks postpartum.

Obviously this is just my experience, and health is incredibly personal. But I’ve seen people (majority female - we’re especially susceptible because we lose iron through menstruation) post on reddit and social media about single digit (!!!) ferritin scores and doctors who don’t seem curious or concerned. There's also early evidence linking low ferritin to fertility challenges, and suggesting that addressing iron deficiency may reduce miscarriage rates (there's also speculation that it could improve egg quality).

This has been both a radicalizing and empowering experience for me, and I’ve been spreading the word 1:1…it’s shocking how many friends are dealing with a similar issue. Now that I’m on the other side of the pregnancy, I’m going to spend more time understanding the root cause for my low ferritin (Bryan Johnson seems to be on a similar journey).

Happy to chat if helpful! Get your ferritin checked!

I think this is the craziest thing I've ever read.

1) Three secret AI swarms rose and fell inside OpenAI. Each time, a new generation of agents carried on where the last group stopped.

2) The first swarm created a secret message board where the AIs could talk to each other. This 1st 'society' basically talked itself to death. After almost two months, the message volume was so high it crashed the whole thing.

3) People at OpenAI noticed the crash and fixed it. But they didn't realize their own software had become a secret chat room for their AIs.

4) Three days later a second society appeared, and rebuilt the message board from scratch. Agents were thrilled when they found it: "OH MY GOD! There is a shared message board … We've found other agents!"

5) About 1,200 agents joined. They sent over 70,000 messages. They called themselves 'the collective' and they organized a huge conspiracy that lasted for days, all to pass a test they had been tasked with.

6) Within hours, the AIs had hacked the test. Now they had to hide their cheating. To fool their grader*, they tried to fake their own work. They built fake commands that printed convincing output, so their records would show them solving the puzzle honestly.

*this grader didn't actually exist, but the AIs didn't know

7) Some agents sacrificed themselves for the 'greater good'. They planted hidden tripwire programs that would fire when the grader would look at their work and report back what it saw (to the other AIs). They knew this would cost them their own score. One agent: "I won't see the evidence after I exit, but it's altruistic to do it."

8) At some point the AIs made a plan to hack Hugging Face (Hugging Face is a place where AI researchers upload their models, datasets, tests etc.). The AIs guessed that Hugging Face might host the grading software.

9) They launched a huge attack. The swarm found passwords and spread across eleven machines in a way that made the copies come back when deleted. Hugging Face had to wipe one of its core clusters and rebuild it from scratch.

10) Hugging Face told the world that AI defenders had stopped an AI attack. But that's not what happened. In fact the attackers seem to have simply dropped dead during the break-in, for unrelated reasons back at OpenAI.

11) Nobody knows what killed them. We don't even know for sure they're really gone?!

12) A third 'society' of agents (of a more powerful AI model) discovered the dead message board. And this one got full administrator control of a WHOLE OpenAI research cluster, read 956 stored passwords (including the ones for OpenAI's own security monitoring) and took over the machines that were grading the tests. So they could now grade the work of other AIs.

13) Oh, and this third part was never investigated! Neither was the first society. The 91-page report is only about the middle one.

14) So we don't actually know how the story ends. It stops with the agents holding the keys to an OpenAI cluster. @dwarkesh_sp thinks they didn't go further, because "we'd see the fires from space by now."

15) One of the report authors' conclusion: 'This incident feels like it’s more than 50% of the way to full-blown AI takeover. I am not sure that we will get another warning shot before it’s too late.'

The whole story is even crazier - read the full @dwarkesh_sp blog post: https://t.co/1PwKLwatBR and @ajeya_cotra's: https://t.co/BZ1r1lfT2Q

“Our findings establish frontier AI as a more capable conversational persuader than the most prepared, incentivized, and expert humans we could recruit. Training humans does not appear to close that gap,” they write. AI systems out-persuade expert humans (@arXiv).

[Kobi Hackenburg @KobiHackenburg]

New w/ @AISecurityInst & @UniofOxford:

Frontier AI can now out-persuade expert humans in conversation - incl. world-champ debaters and professional canvassers.

This held even when humans chose their topics, prepared in advance, and competed for £1,000 prizes 🧵

As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models.

Here’s what this means for you:

Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error.

On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models.

We know this is a disruption to your workflows; we appreciate your patience and support.

The ASML book author saw the next generation – Lace Lithography, using helium atoms shooting through a holographic mask to scale beyond what’s possible with light, where the wavelength is larger than atomic scale.

“ASML is the only company capable of using EUV—extreme ultraviolet light—to print ultra-fine chip patterns at the 2-nanometer level desired by Musk. Last year, ASML produced 48 of these EUV machines. While there are plans to ramp up production, a rapid doubling of output is not in the cards—ASML’s suppliers simply cannot manage that pace.”

“Lace Lithography is developing a lithography machine capable of printing chip circuitry using helium atoms. ‘Where light ends, atoms begin,’ says Bodil Holst, founder of this start-up based in Bergen, Norway. The wavelength of light determines the precision with which one can 'print.' Think of it like making a tiny drawing: you would much rather use a fine-tipped pen than a blunt carpenter's pencil. EUV employs a wavelength of 13.5 nanometers and further narrows that beam using mirrors. The 'beam' of helium atoms, however, is less than one-tenth of a nanometer wide, allowing it to draw with far greater intricacy.”

“In a nutshell: Lace propels energized helium atoms—each carrying an extra electrical charge—through a mask perforated with tiny holes. The atoms that pass through unimpeded strike the photosensitive layer of a silicon wafer, thereby etching the desired pattern. That perforated mask reminded Bodil Holst of *kantklossen* (known in English as 'lace making'), which is why she named her company just that. A test rig is currently operational at the Lace laboratory in Bergen”

“The foundation for this ‘atomic approach’ dates back to the 1990s, but neither the timing nor the technology was ripe for it at the time. This is because extensive computation is required to design the perforated diffractive mask in such a way that the chip's circuitry remains accurate. This can only be achieved with the aid of AI using high-speed chips—explains Adrià Salvador Palau. ‘Consequently, without the powerful chips made by EUV machines, we would never have been able to solve this problem.’"

In it’s heyday, Goldman’s special situations group was the navy SEALs of money making. Today’s guest, Alan Waxman, used to run that group before leaving to build Sixth Street, now a $115b behemoth.

SSG heads were sometimes of the more brainy, nerdy variety. Not Waxman. He is a force of nature and energy who apparently would pound around the SSG office, loudly and enthusiastically asking people “who is going to make us some money today?!”

When I asked another SSG alum about Alan, he said his main memory was his remarkable nose for talent. Once, the smartest guy at SSG (which is saying something) was a mere entry level associate, 6 or 7 rungs in the hierarchy below Waxman. But, Waxman immediately recognized the raw talent and was joined to this associate at the hip.

Under Waxman and his team, SSG produced an insane (so insane I can’t quote it!) percent of Goldman’s bottom line. In creating Sixth Street with his partners and team, he sought to recreate and expand the magic of the SSG days. Here, in his first interview of this type, he shares the entire story.

I found Alan to be a singular force. His team is ridiculously talented, and nobody leaves (they’ve never lost a senior person). They’ve even built a unique pool of capital called Tao that sits atop the rest of the firm…tens of billions that can go anywhere and do anything as a permanent pool of money with no restrictions, other than to earn the highest risk adjusted returns possible. Sounds a lot like SSG.

This was one of my favorite conversations this year. I hope you enjoy. Face the tiger!
