Anthropic now has a team dedicated to AI and the rule of law — and we've just opened our first role. @AnthropicAI has studied what AI means for the economy. This team asks a different question: what will it mean for executive power, for courts and elections — and for the public deliberation that constitutional democracy ultimately rests on? We're looking for someone with real depth in both AI and the law — a legal scholar, political scientist, or experienced government hand who can reason about frontier systems and the institutions they will affect. If that's you, or someone you know: https://t.co/668HDz1lhf

The AI price war has begun. As companies gain access to cheaper and open-source alternatives, the competitive advantage is shifting from owning the best model to delivering the best value. The winners may not be those with the most powerful AI, but those who make intelligence affordable at scale.

But I just published “Automated alignment is harder than you think” (https://t.co/cwpB1ovo2O)! Automated alignment is not the best plan! A better plan is to not build ASI yet, and the world should try hard to realise that plan. Alas, the speed of progress calls for backups. https://t.co/M4hQZxfxdM

A funny thing is that I now get more insightful comments on my posts about obscure science fiction authors or modernist poets or Bauhaus architecture than ever before, but that is entirely due to AI powered slop accounts. Soon broad cultural interest is a sign of AI writing? https://t.co/Lh0N0kj31F

Together with UC Berkeley we are announcing the laser phase plate - a breakthrough in atomic resolution imaging. This is the brightest continuous wave laser in the world, 100 million times the intensity of the surface of the sun. Phase contrast plays an important role in microscopy, but it was thought close to impossible for electron microscopy, where it would require interfering with an electron beam. Holger Mueller and Robert Glaeser proposed exactly this using a standing wave laser. It has taken over 15 years to make this a reality. Biohub partnered with UC Berkeley and Mueller to support this work and to engineer and build the technology. Contrast has been the critical barrier to achieving atomic resolution imaging of the cell. In cryo-electron tomography, a cellular imaging technology that uses electron microscopy, the low contrast makes it impossible to resolve anything but the largest proteins within their cellular context. The laser phase plate removes that barrier. With advances in AI this breakthrough in contrast will start to open up a new frontier in structural biology, that will allow us to see the molecular machines of the cell, and how they assemble into far more complex and dynamic systems, and understand how they work.

@baym @Plinz Just tried fable for the first time. I am kinda disappointed. After I introduced myself, it didn’t stop talking to me :( https://t.co/23XIGbPMH6

My dudes right here! Celebrating all our hard work for GTC Taipei. Nothing but love for @NaderLikeLadder and @Baxate. Proud to work with these two, even prouder to call them friends. #nvidians https://t.co/7S6LJR7XdI

LARRY ELLISON: AI IS RAPIDLY COMMODITIZING BECAUSE MOST MODELS ARE TRAINED ON THE SAME PUBLIC INTERNET DATA. THE REAL COMPETITIVE EDGE ISN’T THE MODEL ANYMORE — IT’S ACCESS TO EXCLUSIVE, PROPRIETARY DATASETS. THAT MAY BE THE ONLY MOAT LEFT. https://t.co/hLBMeTFMl4

Quoting @dlwh : we are at risk of losing the reputation of spiky loss runs! This run incorporates some stability techniques from my past projects: Hyperball, Gated Norm, and Gated Attention. Excited to see the next run from Marin! https://t.co/LJ0jSyOG2O

Since I am on an AI & poetry kick, here is what Fable did with "the Duino Elegies as a game. get the mood right" It made a beautiful little art game, including translating Rilke (though I insisted on bits from A. S. Kline's excellent translation as well) https://t.co/s8TVvG6eg5 https://t.co/YLguas8dd4

in markets, to go long on something is to bet it grows more valuable over time. much of the conversation today is short on humans, wagering that ai makes people redundant. we believe the opposite is true for the industries @ThriveHoldings operates in. we are long humans. https://t.co/oqygDJKZGO

There was a major regression in chart hover performance in Weights & Biases when you had lots of lines per chart and many charts on screen. We just deployed a fix. Its buttery again.

Everyone says the latest AI agents will be "job-ready" soon, especially after the release of Fable 5 this week. But is that really the case? Over the past many months, my group and collaborators have been building Agents' Last Exam (ALE), a benchmark designed to test exactly that claim on real digital labor-market work. My group and collaborators previously have created many of the benchmarks the field runs on, including MMLU, MATH, CyberGym, and ExploitGym. Today, I'm excited to share Agents' Last Exam (ALE): a rolling benchmark that measures whether AI agents can actually perform economically valuable work across a broad range of real-world domains. With ALE, we evaluated Fable 5, GPT-5.5, Composer 2.5, and other frontier agent systems across more than 1,500 expert-sourced tasks spanning 55 occupations. The result is both impressive and sobering. Today's agents can solve a meaningful fraction of professional tasks. But when we look at the hardest tasks, the ones requiring sustained reasoning, deep domain expertise, and reliable execution over long horizons, they are still far from human-level performance. On ALE's hardest tier, every frontier agent we tested, including Fable 5, achieved a 0% success rate. The age of useful agents is here. The age of truly job-ready agents is not. We hope Agents' Last Exam (ALE) will serve as a new guidepost and north star for developing agents capable of reliably performing economically valuable work across a broad range of domains. 🧵
