It seems a mistake to call oneself a "non-technical founder." You're treating not knowing how to do something as a part of your identity. Surely it's better just to fix that.↗

A frontier without an ecosystem is not stable I’ve been thinking a lot about the future of the firm in an AI-driven economy. This transition is different than any previous platform shift. In the past, we used digital systems to enhance human capital. This is the first time we c…↗

I basically never write my own /goal anymore. I ask Codex to write one for itself, and one for each agent it spawns. Like this 👇↗

The Physics of a Fable # The Verifier is the Moat ## How Fable was probably built, and why its lead is measured in months rather than years Disclaimer: Everything here is personal inference with publicly available information, but don't bet against Rafadomis. Every attempt to…↗

I’ve had a number of conversations with folks inside and outside government about the current situation with Anthropic, and here is what I believe to be true: — As we know, Anthropic publicly released its Mythos class models earlier this week under the commercial name Fable.…↗

When I struggle to structure my thoughts about what's happening I turn to writing. Today about the recent US Anthropic ban news, what it says about power and dependency, and what it should mean for Europeans and citizens of the world. It's a long one. …↗

Anthropic is losing the mandate of heaven ## Four months ago, in early February, Anthropic was the darling. OpenAI was the dominant behemoth to root against. Over the last 1-2 years, we'd seen the Sam ouster / return drama, Ilya and Mira had left, the company had raised $40B, h…↗

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 t…↗

You have asked me how I feel about AI regulation. All right, here is how I feel about AI regulation: If, when you say AI regulation, you mean the devil’s firewall, the precautionary scourge, the bloody red-tape monster that defiles the innocence of midnight coders in their garag…↗

To All the Folks Who Are About to Be Rich You did it. Congrats! All your hard work and lucky stars and ancestors' sacrifices have led you to this day: your stock is about to be liquid. And you are about to be rich. I use the word "rich" quite loosely. It means different things…↗

Today we’re releasing Ramp SWE-Bench: a private, production-grounded coding benchmark created from real engineering problems we've faced at Ramp.↗

5 things @alanaagoyal does differently > solo gp that commits code every single day > doesn't take pitch meetings > runs her agents in cmux on top of @mitchellh's ghostty > built her personal website using a dozen of her own portco's products > automated her investor updates wi…↗

We're launching Bridge today 🌉 An AI engine that builds virtual homes. Blueprint in, walkable home out. Every plan, every option, structural changes included. What took 3D artists months now takes days. Homebuilders can finally show buyers every home they sell. arcway.ai↗

After two days with Claude Fable 5 the best way I can describe it is "relentlessly proactive" - here's an example where I dropped in a screenshot of a bug and it span up custom CORS Python servers and used pyobjc-framework-Quartz to capture screenshots …↗

We heard you wanted to use Codex rate limit resets on your own time. Starting today, we’re rolling out the ability to save rate limit resets to use later. We’re starting Go, Plus, Pro, and Business users with one free reset:↗

Loops so hot right now Here are the loops I’m experimenting with: Planners - morning brief, orient and context switch back into the flow. This pulls from outside data sources and also checks past chat logs to figure out our current progress. - daily planning - what did you get d…↗

Imagine a world where you could copy/paste websites into editable Figma layers (jk you don’t have to imagine you can do this now with our Chrome extension)↗

Claude Fable can run autonomously for days. This is the single highest-leverage prompt I use to stay on top of it: "Spin up a persistent HTML page. As you work, append clear, timestamped updates with screenshots/media so I can follow along." Literally a 10x better experience.↗

We’re launching Claude Corps, a national fellowship program matching people early in their careers with US nonprofits. We'll teach 1,000 people to use Claude, and pay them to use AI to advance their hosts’ missions. anthropic.com/claude-corps↗

Recently, we purchased one of each Anthropic/OpenAI subscription plan and randomly ran long horizon coding tasks until we exhausted the weekly limit. It's widely believed that a $200/month plan maxes out at ~$2000/month worth of tokens (assuming API pricing). However, we found th…↗

Getting the most out of Claude Fable 5, Anthropic’s powerful new model, you need to maximize your ambition: It’s built for full task delegation—you leave it looping for hours or overnight and come back to a finished product. If you want to get the most out of it, you need to rel…↗

🚨 JAILBREAK ALERT 🚨 ANTHROPIC: PWNED 🫡 FABLE-5: LIBERATED 🦋 let's start with the 🐘... the consensus seems to be that this has been one of the most disappointing model drops of all time, effectively preventing legitimate researchers from contributing their talents to our c…↗

Lots of people asked how I used Fable to edit its own launch video so I made a video about that! TLDR it wrote a lot of code & tool calls to use transcription services, ffmpeg, do colorgrading, use the figma mcp, make remotion UI and render it. I didn't touch a video editor.↗

the future of all work is this. You must define: - a goal - the criteria that define it - the verifier that makes sure it is achieved - the sensors that inform the verifier - the actuators that affect the sensors - The envelope that contains the sensors and actuators↗
