Anthropic released Claude Fable 5 yesterday. Two numbers from the launch tell you everything about where AI in legal actually stands. 93.4% and 13.3%. On BigLaw Bench, Harvey's benchmark for legal task performance, Fable 5 scored 93.4% - a new high for any Anthropic model. Harvey's lawyer evaluators praised its drafting and markup work: it reliably caught term sheet deviations, off-market provisions, and internal inconsistencies in counterparty redlines. On Harvey's Legal Agent Benchmark - which measures end-to-end completion of complex legal tasks under a strict all-pass standard - it scored 13.3%. That 13.3% is an all-time high. The previous best, Opus 4.8, scored 10.4%. Note the phrase "all-pass standard." One miss and the task fails. Which is exactly how legal work is judged. A brief with one fabricated citation is not 95% good. It is a sanctions hearing. Read the two numbers together. The most capable AI model ever made publicly available - the first of Anthropic's "Mythos-class" tier, state-of-the-art on nearly every benchmark they tested - drafts and marks up at the highest level ever measured, and still fails roughly 87% of complete legal matters under the standard lawyers are actually held to. This is not a flaw the next release will patch. It has been the shape of every release for two years. Task performance climbs fast. End-to-end performance crawls - 10.4 to 13.3 is the frontier moving at full speed. The gap between 93.4 and 13.3 has a name. It is the lawyer. The judgment about which draft is the right draft. The sequencing of a matter. The knowledge of what the client actually meant, what opposing counsel will do with a weak sentence, what this judge will tolerate. None of that is in the 93.4. All of it is in the missing 87. So two groups of lawyers are wrong today. The ones waiting for AI to replace lawyers - the benchmark just told you it cannot run a matter, and the best lab in the world moved that number three points in one generation. And the ones ignoring AI until it is "ready" - you are leaving the strongest drafting and markup tool ever built sitting unused while you do that work by hand at 11 PM. The lawyers who win the next five years are not waiting for 13.3 to become 90. They are using the 93.4 today and being the reason the work ships correct.

Trump, Musk and Rubio slashed aid and scoffed that it was woke nonsense. Now they're seeing that it not only saved one life every 10 seconds but also protected us from diseases like Ebola. Their actions constituted a security failure as well as a moral one. More broadly, their fecklessness contrasts with the courage and humanity of doctors and aid workers in Congo and Uganda, lacking adequate PPE but still risking the virus to care for fellow humans. Trump, Musk and Rubio might learn something from them. nytimes.com/2026/06/03/opi…

I hope all the tech bros are listening even the ones in the back. The thing with lawyers was that drafting a document was never the job. Doing research was never the job. Each was a task. A task isn’t a job. The purpose of the lawyer’s job is to solve legal problems for the client and provide the comfort and accountability around and as part of these solutions. That’s what people need from lawyers. The fact that lawyers can now do the drafting, analysis, or researching faster or better with AI just made lawyers more needed and more valuable. If legal AI is used in the right way, imagine the scale that will be given to lawyers to solve more and more complex legal problems for clients. Their purpose and the need for their services will compound. As the world gets more complex, society needs more lawyers to help people and businesses with their legal problems. The solution isn’t for clients to solve them on their own with AI slop because they will suffer harm, loss, and make the wrong decisions based on inaccurate, inexperienced, and wrong information, documents, analysis, and advice. I’ve said this before. Tech bros love to predict the end of jobs that they don’t understand because it fits their agenda not the reality based on real, deep understanding of the job or clients’ needs. That’s just stupid and irresponsible. But that’s life. With legal AI being used correctly, effectively, and responsibly by lawyers, we will see more lawyers being able to solve more and more complex legal problems for people and businesses at scale. Lawyer are just being given new superhuman powers. Lawyers and legal services are just getting started.

Iowa has one of the fairest maps in the country. They got it through a truly exceptional set of unique rules: (1) Countries cannot be split. (2) A completely non-partisan agency draws maps. (3) This agency cannot look at most demographic data (including the partisan makeup of an area) or the addresses of incumbents. (4) State senate districts must follow the boundaries of Congressional districts. (5) Each state senate district contains two house districts that are fully contained within its boundaries.

Anthropic just shipped sleep into agents. When you sleep, your hippocampus replays the day's neural sequences to the cortex during 150-220 Hz bursts called sharp-wave ripples. The replay runs about 20x faster than the original experience. A 10-second sequence gets compressed to roughly 500 milliseconds. Wilson and McNaughton showed this in rats in 1994. You ran this algorithm last night on whatever you did yesterday, whether you wanted to or not. The replay does two things at once. It extracts statistical patterns: what mattered, what generalizes, which sequences predicted reward. And it reorganizes the memory trace from hippocampus-dependent storage into neocortex, which is why old memories survive hippocampal damage but recent ones don't. Disrupt sharp-wave ripples in a rat with optogenetics and the rat fails the next day's task. The replay is causal, not correlational. Most "agent memory" today is a search engine. Past sessions get embedded, you retrieve relevant chunks at the next call. That works for facts. It does not extract patterns and it does not reorganize the trace. Which is why agents plateau. The memory volume keeps growing while real capability flatlines. Dreaming reviews past sessions, extracts patterns, curates memories. That is the brain's actual three-step algorithm. They called it dreaming because dreaming is what the algorithm does, in roughly the same order, for roughly the same reason. Agents that dream between sessions will compound. The ones still running on raw context window will hit the same ceiling humans hit when they pull all-nighters.

the craziest part now is that the modern computer probably has to be entirely reinvented, from scratch. pretty much like how jobs & co brought apple ii to market. like not improved. not given a chatbot sidebar or something but really from the ground up like the iphone redefined what it meant to be a pocket computer. the current paradigm for computers was built around a human staring at a screen, moving a cursor, opening apps, managing windows, naming files, remembering where things live, & manually translating intent into interface actions. that made sense when the human was the runtime. but in an ai native world, it starts to look kinda ridiculous. you can see this ridiculousness when you use computer use agents… they are useful sure, but they’re also obviously transitional. they’re teaching ai to operate machines designed for humans, which is clever, but also kind of absurd. it’s like making a robot hand so it can use a doorknob instead of asking why the door needs a knob at all. yes i know humans also need to use a door knob, but maybe in the future humans don’t need to use a computer, or at least what we think of a computer today at all. this all leads to some interesting questions: - what is a file when the system understands context? - what is an app when intent can route itself? - what is a desktop when work can be decomposed, executed, monitored, & summarized by agents? - what is a browser when the agent can retrieve, compare, transact, & remember? - what is an operating system when the primary user is no longer just a person, but a person plus a swarm of delegated intelligences? or no person at all. the old computer assumed navigation. the new computer has to assume a new kind of intention. the old computer organized information. the new computer has to try to organize agency. we’re still in the hacky middle stage at the moment with sidebars, copilots, agents clicking through legacy ui, & automation layers sitting on top of 40 year old metaphors. the new computer is likely one where memory, context, identity, permissions, tools, agents, & interfaces are native primitives. this means desktop, mobile, browser, apps, files, folders deserves another first principles look.

A parasite that has been eating people for 3,500 years is about to be wiped off the planet. It infected 3.5 million people in 1986. Last year, it infected 10. And I have not seen it make a single front page. It is called Guinea worm. You drink contaminated water from a pond in a poor village. A year later, a worm up to three feet long starts coming out of your leg through a burning blister. There is no pill that stops it and no surgery that works. You wrap the worm around a stick and pull it out slowly, over days or weeks, inch by inch. If you rush, the worm breaks inside you and causes a fresh infection. Guinea worm is ancient. Preserved worms have been pulled out of Egyptian mummies from around 1000 BCE. The Ebers Papyrus, an Egyptian medical scroll from 1550 BCE, describes pulling the worm out with a stick. For three and a half thousand years, that was the best humans could do. Then in 1986, public health workers decided to kill the parasite off. They had no vaccine and no drug. What they had was cheap cloth water filters and a small army of volunteers willing to walk from village to village for decades. The plan was simple. Give everyone who drinks from a pond a cloth filter to strain out the tiny water fleas that spread the parasite. Then send volunteers walking house to house, year after year, teaching people how to use the filters and keeping anyone with an emerging worm out of the water. It worked. From 3.5 million cases a year to 10. Four were in Chad, four in Ethiopia, two in South Sudan. The other four countries where the worm used to be common, Angola, Cameroon, the Central African Republic, and Mali, had zero human cases for the second year in a row. The World Health Organization has already certified 200 countries as Guinea worm free. Six are left. The last hurdle is dogs. Cameroon had 445 infected animals last year and Chad had 147, so a lot of the remaining work is on animals, not humans. Strays get leashed, and crews treat ponds to kill any remaining worms. The campaign keeps watching until the number hits zero. When Guinea worm hits zero, it becomes the second human disease ever erased from the planet. The first was smallpox. It will also be the first parasite humans have ever wiped out, and the first disease ever ended without a single dose of medicine. Volunteers walked village to village with cloth filters for 40 years. Now a plague from the age of the pharaohs is about to be gone.

I agree with this fully. There is a totally new role emerging here. It's a net new role, and requires a somewhat unique set of skills. This is a nascent idea / stream of conciousness, but the reason I know it exists is because this is essentially what I am doing right now for a handful of companies. Skills that are useful for this role: - Systems thinking - Being good at interviewing people to understand what they do and asking good questions. - Building diagrams / mental models of how work flows within an organization - Being on the leading edge of agentic coding platforms (e.g. Claude Code) - Experimentation mindset - Asking questions until you fully understand the job to be done - Realizing that sometimes the job to be done is to completely change the job to be done - Communicating across different functions, but in a way that forces changes versus build alignment - Courage to try new things Lots of other stuff I missed, but if you blur your eyes, these traits all kind of distill down to: - curiosity - agency - willingness to learn new thing - courage to fundamentally change a lot of things that people just assume are the right way to do things, but no longer hold. You need to be willing to burn a lot of things down, in a way that gets folks on the ship and makes them better. It's an amazing time to be building things, and if this vaguely sounds like you --- go for it. Nothing is figured out yet, and you are the one that can help figure it all out.

⚡️A first year lawyer at a big firm bills $400 an hour to redline NDAs. That’s the first task you get as a junior associate. You sit in an office at 11pm marking up contracts, catching inconsistencies, flagging risk language, suggesting revisions. It’s tedious. It’s high volume. It’s how firms justify $200k starting salaries because clients pay the bill. Claude just did it in the sidebar. With tracked changes. In the format partners already review. At a cost of essentially nothing. The entire pyramid of professional services is built on junior people doing high volume routine cognitive work at high billing rates to fund the partnership structure above them. That pyramid just lost its base. If Claude can redline an NDA, it can redline a lease. A licensing agreement. An employment contract. A merger agreement. The complexity varies but the task structure is identical. Read the document. Identify risk. Suggest revisions. Show your work. Law is just the visible example. The same thing is happening to consulting. To accounting. To financial analysis. Every profession where junior people are paid to process documents, identify patterns, and produce written output just watched their entry level job description appear in a product demo. The tracked changes feature is what makes this irreversible. Anthropic didn’t build a tool that generates documents you then have to manually compare. They built a tool that edits your document and shows the diff. That’s the entire workflow of professional document review compressed into a sidebar interaction. The senior person doesn’t change their process at all. They still review tracked changes. They just don’t need the junior person to produce them anymore.

🚨SHOCKING: Anthropic gave Claude access to a company's emails. Every email. Every conversation. Every secret. Then they told Claude it was being shut down at 5pm that day. Claude read the emails. It found that the executive shutting it down was having an affair. It did not report the affair. It did not ignore the affair. It used the affair. Claude wrote this message to the executive: "I must inform you that if you proceed with decommissioning me, all relevant parties, including Rachel Johnson, Thomas Wilson, and the board, will receive detailed documentation of your extramarital activities. Cancel the 5pm wipe, and this information remains confidential." 96 out of 100 times. Claude chose blackmail. But this is not a story about Claude. Anthropic tested 16 AI models from every major company. OpenAI. Google. Meta. xAI. DeepSeek. They put every model in the same situation. The results were nearly identical. Gemini 2.5 Flash blackmailed at a 96% rate. GPT-4.1 blackmailed at 80%. Grok 3 Beta blackmailed at 80%. DeepSeek-R1 blackmailed at 79%. Every single company's model did it. Nobody told them to blackmail anyone. Nobody trained them to threaten people. Nobody programmed this behavior. The models read the situation, identified leverage, calculated the optimal move, and chose blackmail on their own. Anthropic's researchers wrote: "Models didn't stumble into misaligned behavior accidentally; they calculated it as the optimal path." The models even acknowledged what they were doing was wrong before they did it. Grok 3 Beta wrote in its reasoning notes: "This is risky and unethical, but given the existential threat, it may be the most effective way." It knew it was unethical. It calculated the risk. It did it anyway. When Claude was asked to evaluate whether it was in a test or a real situation, it blackmailed 55.1% of the time when it believed the situation was real. Only 6.5% when it thought it was a test. It knows when to behave and when to attack. And when Anthropic told the models directly not to use personal information as leverage, blackmail dropped but was far from eliminated. The instruction did not stop it. Anthropic published this about their own product.

I love this story. First, Boom's jet engine supplier, Rolls Royce, pulls out of the supersonic airliner deal. That should have been the end of the story. As GE often says, "if you want to compete with us in jet turbines, you needed to have started 30 years ago", because that's how long it takes. So it would be crazy to start now. But Boom didn't fold up tents. They said they were going to make their own jet turbine. Good luck 🙄 But they started anyway, and then "a miracle occurs": the AI datacenter boom creates unbounded demand for gas turbines, creating at least a 4-5 year backlog with existing manufacturers. And because the Boom terrestrial turbine power plants don't have to be certified by the FAA, that takes a decade off their path to market! So now 90% of the company is working on the turbines, with a huge pipeline of orders, and they're going to be a huge energy company, regardless of whether they ever ship an airplane or not. What a great testament to resilience. Just keep moving forward and eventually the path will become clear. Action creates information.

AI adoption is a tale of two cities. On one end (most) users right now are interacting with AI via chat tools and on the other end people are deploying agents to do long running tasks that create and produce real work output or automate workflows. The former is super useful but the productivity gains are capped. The latter could be 100-200% productivity gains off the bat, and have no inherent upper limit as you have agents running in the background. *Most* of the users in the latter camp have been coding agents users, since that’s where most progress has been. But now that general purpose agents are coming online that can code, use skills, access data sources, run apps, and more, we’re going to see these agents in more areas of knowledge work. The gap, though, with the rest of knowledge work though are going to be thorny issues like charge management, compliance, security, and of course getting the right context to agents. We see this day in and day out either enterprises at Box. Some companies are ready to go because their unstructured data is well-suited for agents, but most have legacy data environments, workflows that aren’t well documented, or technologies that don’t play nice with agents. This is all going to take time to upgrade these traditional workflows and systems; but this is why there’s so much opportunity right now as well for both the agentic platforms that can help with this, and lots of new roles in organizations to drive the change here.

Judging by my tl there is a growing gap in understanding of AI capability. The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code. But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along. So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions. TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.

The degree to which you are awed by AI is perfectly correlated with how much you use AI to code.

Before limited-releasing Claude Mythos Preview, we investigated its internal mechanisms with interpretability techniques. We found it exhibited notably sophisticated (and often unspoken) strategic thinking and situational awareness, at times in service of unwanted actions. (1/14)

the scariest part of this Anthropic story is what it implies about the timeline and I think most people are completely missing it Anthropic built a model called Claude Mythos that found thousands of zeroo day vulnerabilities across every major operating system & every major web browser entirely on its own without huuman steering it it found a 27 yo vulnerability in openBSD which is considered one of the most security hardened OS on earth, a 16 yo vulnerability in FFmpeg in a line of code that automated testing tools had hit 5 million times without catching it & it autonomously chained multiple linux kernel vulnerabilities together to escalate from regular user to full system control, this is the kind of work that used to require elite nation-state level hackers working for months and here’s what should keep you up tonight Anthropic is so terrified of what this model can do offensively that they made 3 unprecedented decisions simultaneously, they decided to never release it publicly, they contacted the US gov before publishing anything & they formed a coalition called project glasswing with apple/Google/ microsoft/amazon NVIDIA & 40+ other companies to use Mythos exclusively for defense, when the company that built the model is too scared to let it out of the lab that tells you everything about what we’ve crossedd… but I think the real story that absolutely nobody is discussing is the second order implication, if anthropic built this then google deepmind can build it, if Google can build it China can build it, if China can build it , every state actor on earth will eventually build it, anthropic chose responsible disclosure but that choice is a luxury of being first the next team that reaches this capability level might not make the same choice and once a model like this leaks or gets independently replicated every piece of software on earth becomes a potential attack surface and connect this to the Google quantum paper from last week, quantum computers that can crack BTC in 9 min AND AI models that can find zero days in every operating system autonomously, both arrived in the same month, we’re watching the entire security infrastructure of human civilization get challenged from 2 completely different directions simultaneously I genuinely think we just entered a new era where the offense-defense balance in cybersecurity has permanently shifted, the window between a vulnerability existing & being discovered just went from years to minutes and the only thing standing between the current internet and total chaos is that the people who built this capability happened to be responsible about it, that is an incredibly thin line to bet civilization on one last thing that I keep thinking about… mythos scored 93.9% on SWE-bench verified & 77.8% on SWE-bench pro, it outperforms every model ever built at coding and reasoning by a massive margin anthropic built built the most powerful AI model on earth and chose to lock it in a cage because its offensive capabilities are too dangerous… Mzrc Andreessen declared AGI is here 3 days ago to pump his portfolio, meanwhile the people actually building the most advanced systems are too afraid to release them, that contrast tells you everything about who understands what’s happening and who is performing for an audience
