The core guiding principle of the lab is: scale up along every damn axis!! 🚀\n\nRobotics data is NOT a second-class citizen - it is too important of a problem to be left to fine tuning! Your model needs to see your most important tokens from step 0\n\nWe need to think about robotics through the first principles of AI: how do we best utilize the vast amounts of web-scale media and how do we create a data-flywheel to collect millions of hours of rich robot interactions. There is no other moat in AI outside of data and @1x_tech has done an INCREDIBLE job scaling manufacturing, production and hardware to build humanoid robots that can create a unique data-flywheel in unstructured environments. Scaling data collection for highly dexterous on-policy robot data will be the only way for creating a moat in AI. @JackMonas and team have made great progress in building World Models, and now the goal is to supercharge this effort by starting a  hyper-focused scale and data-pilled lab. \n\nBefore scaling compute / data / models, we are currently RAPIDLY scaling our team and hiring across the 4 core pillars of AI: model + data, data infra, ML infra and evals. Looking for folks that are excited about the 0->1 problem and share the same principles as us. There’s a single application for everyone in the lab - if you’re a good at engineering and ML, we will find a place for you in the team ❤️\n\nAGI won’t be solved by fine-tuning… Let’s build the next frontier of AI together 🚀 \n\nMy DMs are always open!!","author":{"name":"Samarth Sinha","username":"_sam_sinha_","avatarUrl":"https://pbs.twimg.com/profile_images/1801003768106131457/2Z-Atu_9_200x200.jpg"},"createdAt":"Thu Jun 04 16:26:11 +0000 2026","engagement":{"replies":60,"retweets":28,"likes":419,"views":93982},"quoteTweet":{"id":"2062570067305570671","url":"https://x.com/BerntBornich/status/2062570067305570671","text":"We’re going all in on World Models.\n\nToday we’re launching the 1X World Model Lab.\n\nThe bet is simple:\n\nYou can’t fine-tune your way to AGI.\n\nAnd you definitely can’t fine-tune your way to robots that can operate in the physical world.\n\nGeneral-purpose humanoids need models that understand space, motion, objects, causality, affordances, physics, and action before they ever see a specific task.\n\nThe frontier is not better VLA wrappers.\n\nThe frontier is embodied world models.\n\nThe 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.\n\nThe next frontier in AI requires scaling: \n\nweb-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\n\nThe robot collects data.\nThe model gets better.\nThe robot gets better.\nRepeat.\n\nTo lead this, we brought in one of the best for the mission: @_sam_sinha_ , as Head of World Models.\n\nSam was a founding research scientist at Luma AI and has been at the frontier of scaling multimodal generative video models his whole career.\n\nIf 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.\n\nSend background + evidence of exceptional ability to:\n\nwmlab@1x.tech\n\nWe’re building the model that makes autonomous labor real.","author":{"name":"Bernt Bornich","username":"BerntBornich","avatarUrl":"https://pbs.twimg.com/profile_images/1950664588950949888/VHyelX2P_200x200.jpg"},"createdAt":"Thu Jun 04 16:19:59 +0000 2026"}}
