It is built from 189 demonstration videos, broken into 222 reconstruction tasks, and graded on three things: whether the geometry looks right, whether the physics behaves correctly, and whether the simulation actually runs and does the task. Researchers ran nine frontier coding-agent systems through it. Nearly all of them succeeded on fewer than 5 percent of tasks, until Claude Opus 5 pushed that number past 15 percent - still a minority of attempts, but a sharp jump from everything that came before it, and the paper notes even that leading score trails well behind reconstructions built with a human in the loop.\n\nThat gap matters because video-to-simulation is the pitch behind a lot of recent robotics and world-model research: skip the manual environment building and calibration, and let an agent reconstruct a usable training ground straight from footage. The paper's more interesting finding is that an agent's output can look convincing and still fail the task - visual fidelity and functional correctness did not track together.\n\nThat is a familiar lesson from image and video generators, which have spent two years teaching everyone that something can look exactly right while being completely wrong underneath.","[\"coding agents\",\"robotics\",\"simulation benchmarks\",\"world models\"]","2026-10-12T04:00:00.000Z","2026-10-12T10:37:31.952Z","2026-10-12T10:37:37.571Z","published",null,[],"ai",[26,27,28,29],"coding agents","robotics","simulation benchmarks","world models",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.04432",0,{"sections":36},[37,41,46,51,56,61,66,71,76,81,86,91,96,101],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",6967,"2026-10-12T15:20:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",954,"2026-10-12T14:20:37.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Policy","policy",496,"2026-10-11T20:06:43.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",492,"2026-10-12T14:55:53.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",237,"2026-10-12T13:24:45.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Science","science",196,"2026-10-11T15:34:40.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",192,"2026-10-12T14:07:13.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Startups","startups",121,"2026-10-12T13:22:34.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",115,"2026-10-11T07:34:45.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Dev Tools","dev-tools",111,"2026-10-12T11:22:24.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",71,"2026-10-12T16:10:40.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Gaming","gaming",59,"2026-10-09T11:43:43.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"Reviews","reviews",35,"2026-10-12T14:00:00.000Z",{"name":102,"slug":103,"count":104,"latest_published_at":105},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
