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…

you're absolutely right. but a movie just isn't the right medium to tell an intelligent story. Silicon Valley awaits its great novel. maybe Melville just needs one last whaling trip to gather the information he needs.

GPT-5.5 lies constantly, Grok 4.20 doesn’t. We made a simulation to see if AI lies when the stakes are life & death.🧵

We're finally shedding the .so (thank you Somalia!), and using the .com for @NotionHQ. And for this beautiful moment, I want to share a fun story: Back in 2018, I had just joined Notion, and one of the first things @ivan asked me to do was figure out how we could own notion.com. I had never done a big domain purchase before, so I reached out to a few domain brokers to understand the landscape. We tried different brokers, kept things anonymous, and attempted to surface a price the seller might consider. A year went by… nothing. Meanwhile, it was pretty clear this was only going to get more expensive as we grew. We needed a different approach. A fellow founder connected me to a broker who took a very different tack. Less transactional, more long-term relationship builder. He spent months getting to know the domain owner. Turns out owner was a fellow entrepreneur in the west coast… and a huge Grateful Dead fan. So we figured, why not get creative? Something beyond just price. So I called up our investor Ronny Conway and asked if there was any way he could help set up a private meeting between the domain owner and the Grateful Dead. Ronny is one of those people who somehow makes impossible things possible. A week later he calls me back: “New York City. Halloween. 15 minutes after the concert. Done.” The broker went back to the owner with an offer: some cash, some equity, and a private meeting with the Grateful Dead. That got his attention. He didn’t take the band meeting in the end, but he did lean into the equity (great call, in hindsight). We shook hands, and a few weeks later, the deal was done. I’ve been waiting years for the day we move our product to notion.com. Looks like 2026 is finally the year. Safe to say I’m unreasonably excited about this update!
