Open source world models have a fantastic new player! Interactive world models have had the same flaw for a while now. They look great for a few seconds, then the world quietly falls apart. Textures smear, geometry warps, drift wins. Robbyant's new LingBot-World 2.0 is the first one I've seen really push past that. It's a causal world model you explore in real time at 720p and 60fps, stress-tested with a single unbroken 60-minute session across 20 scenes with no visible decay. Staying coherent for that long is the actual hard problem, and that's the result here. The part that got me is the agent loop on top. A VLM proposes events while you play and a director agent keeps seeding new things to do, so the world keeps unfolding instead of sitting still. Movement, combat, weather on demand, even multiplayer in one shared world. And Robbyant, Ant Group's embodied-AI company, open-sourced the model weights and code. A 14B model is released, and the paper also describes a 1.3B version designed for single consumer-GPU deployment, with weights and code available. There's a live demo, hosted by their launch partner Reactor, you can just play. @robbyant_brain #ad
