Congress passed a nuclear energy bill 88–2. Red and blue governors are siting reactors. Tech giants are investing. I wrote about how fission might be teaching us to build together again: open.substack.com/pub/dannys… ⚛️ #nuclear #energy #abundance @oklo @caorilne

Beginning today, we are industrializing nuclear battery production at the historic Vallecitos Nuclear Center. With this facility, we will deliver our first nuclear battery to customers in 2027 and scale production in 2028 - powering critical missions from the seabed to the lunar surface.

We’re going all in on World Models. Today we’re launching the 1X World Model Lab. The bet is simple: You can’t fine-tune your way to AGI. And you definitely can’t fine-tune your way to robots that can operate in the physical world. General-purpose humanoids need models that understand space, motion, objects, causality, affordances, physics, and action before they ever see a specific task. The frontier is not better VLA wrappers. The frontier is embodied world models. The 1X World Model Lab will focus on large-scale embodied world model pretraining: building the most generalizable foundation model for humanoid robots from the ground up. The next frontier in AI requires scaling: web-scale media + egocentric human videos + sim + dexterous remote operated robot data + on-policy NEO data → real-world deployment for robot data collection and RL → abundance of data → physical AI The robot collects data. The model gets better. The robot gets better. Repeat. To lead this, we brought in one of the best for the mission: @_sam_sinha_ , as Head of World Models. Sam was a founding research scientist at Luma AI and has been at the frontier of scaling multimodal generative video models his whole career. If you’re the best in the world at large-scale pretraining, video models, robotics, RL, infra, or data — and you want your models to move atoms, not just pixels — join us. Send background + evidence of exceptional ability to: [email protected] We’re building the model that makes autonomous labor real.

The bottlenecks are shifting: Not just algorithms → but energy, manufacturing, and infrastructure.

Anyone else (re)reading The Grrat Gatsby for its centennial thanks to @mikiebarb ? It’s probably been over twenty years since I first read it and it’s a delightful revisit! Definitely hits differently this read around. #thegreatgatsby

“The world has really changed in the last four weeks with over $1.1 billion in investment, including Oklo ... Given the traction and tailwinds from the executive orders ... if there are opportunities to go faster and scale more quickly, we'll explore those,” Oklo co-founder and CEO Jacob DeWitte tells @BloombergTV. bloomberg.com/news/videos/20…

On this day, December 20, 1951, the Experimental Breeder Reactor-I (EBR-I) became the first reactor to generate usable electricity! 💡 Its successor, the EBR-II, operated for decades and paved the way for Oklo's fast reactor design. Learn more about this demonstrated technology with over 400 combined years of operational experience: oklo.com/technology/default.…
