Next up on First Pass: A conversation with @adijayaprakash from @useblacksmith Everyone knows about the GPU crunch, but the CPU crunch is getting equally painful. In this episode we talk about the nuances of CPU clouds and how agents are driving a surge of CPU demand
Verifiable AI will be a huge trend!
The world is debating whether frontier AI needs to slow down. If it comes to it, do we know how? A lab can say it stopped training. A country can sign a treaty. But, is the compute following the rules? @attestable is building that layer. New blog! 🧵
Remotely installable, remotely verifiable, this is the verification solution the world needs. We are working hard @attestable to make it as fast and easy to deploy as possible.
We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so. Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our
Very well written post from Dario. The US must dominate in AI. And we must do it responsibly. In 1957 the International Atomic Energy Agency (IAEA) was formed. The IAEA stemmed from President Eisenhower's 1953 "Atoms for Peace" proposal. In very over simplified simple terms, the IAEA purpose was to ensure safe use of nuclear technology across the world. Verify that where uranium was being enriched, the enrichment levels were enough for energy but not enough to make a bomb (low single digit percentages not 90%). What could be used for good (energy) could also be used for bad (bombs). We needed a global institution to help ensure the bad uses weren't happening. Failure would be blocking this technology from being used for good.... They did this with specialized tools and site visits, forensic investigations, and ongoing monitoring solutions Doesn't sound too different from what Dario is proposing with Embedded Evaluators! Independent third party actors with desks in their office, company laptops, access to company workspaces, etc Back to the nuclear analogy. Fast forward to the late 70's / early 80's and the United States canceled the development of 100+ nuclear reactors (Three Mile Island partial meltdown in '79 caused a lot of the fear). What's important though is the IAEA didn't shut down development, fear did. The US then went 30+ years before building a new one. As @altcap discussed on CNBC yesterday, what's important is having balanced discussions about the risks. We don't need hyperbolic hypothetical statements that drive fear. The Hugging Face incident kick started fear, just like the Three Mile Island incident did in 1979. Too much fear (without balanced discussion) will lead the US AI's dominance to the same fate it's nuclear dominance fell to The US is now paying for the reactor freeze from the late 70's. Our energy dominance is diminishing. We're seeing a huge power crunch. While we paused, other countries marched on with reactor development. Unfortunately, China and Russia particularly. France is also a gold example, with well over 50% of their electricity today from atomic energy. The full circle irony - Three Mile Island is now being re-opened and redeveloped for AI data centers. The "Hugging Face incident" of the nuclear era is now coming back for AI. We can't let fear grip us and force a similar pause in AI. And I think it's important to point out Dario isn't asking for a pause. He's asking for responsible pacing. These are different. The IAEA didn't cause a pause. Embedded Evaluators similarly won't be the reason we stop building data centers. I thought Dario's post was well written and balanced. However, we can't fall into a cascading fear loop. This is what our adversaries want (look who's now dominating nuclear while we play catch up...) It's imperative that the discussions around the risk are grounded in reality and good faith. Dario's essay is a great step

@chetanp Agree! x.com/jaminball/stat…
On @Cnbc today to discuss how the labs, gov’t and industry are working together to balance massive AI benefits w downside risks. And why leaders like @andrewdfeldman agree w @JensenHuang calling Coxon’s dangerous claims of human extinction “utter horseshit.” 🧐🧐
“pointed to a cryptography tool called zero-knowledge proofs — a mathematical way of providing verification about a system without revealing more than necessary, such as proprietary details about model parameters or training data.” - Fields medalist and @OpenAI researcher nytimes.com/2026/09/08/sci…
This is the future, @attestable will usher it in! Zero knowledge proofs are about to become mainstream and very important in the AI domain nytimes.com/2026/09/08/sci…
Excited for Altimeter portfolio company @HQ_Covenant to emerge from stealth with $250m in funding and ~$150m in orders. Deep precision strike is one of the most critical capability gaps facing the West. Covenant has built Anthem to close that gap and meet the need for long-range, heavy payloads, precision, and mass production. Proud to back Michael and the truly special Covenant team as they bring Anthem to the world.
Today, Covenant is emerging from stealth and introducing Anthem: a heavy-payload deep precision strike capability designed for mass production, with deliveries beginning in the thousands in 2027. We’ve raised $250 million, flown Anthem in more than 200 tests, and secured
Let’s go!

Excited to back @ScottWu46 and the @cognition team!
The world needs far more software than it can build. Cognition exists to change that. We’ve just raised over $2B at a $48B valuation, led by a16z, Accel, Founders Fund, General Catalyst, and Avenir. Since our round in May, run-rate revenue has grown from $492 M to almost $900
You only need to listen to 2 minutes of this episode with @ZachBDell to feel like an expert. Very clear and concise “We look at a very simple correlation of consumption of energy per capita to GDP per capita. The takeaway is the more energy a population is able to consume, the better their life gets.”
