That constant replanning is safe but computationally expensive, and simply caching a plan only works if you know when it has drifted too far from reality. The researchers built a framework analyzing how prediction mismatch propagates through local dynamics, then used it to create AdaReP, a training-free wrapper that adjusts a plan's shelf life based on real-time deviation from the cached rollout and a local sensitivity estimate. It requires no changes to the underlying world model or planner, and was tested on image-space planning, latent-space control, and real-world robotic manipulation.\n\nCompute is the bottleneck holding back real-time robot control with learned world models, since replanning every step can be prohibitively slow on physical hardware. AdaReP's results suggest that bottleneck is partly self-inflicted: in a 50-trial physical robot study, it cut planner queries by more than 80 percent while matching task performance.\n\nIt is a tuning trick, not a new world model or planner, but if the gains hold up outside curated benchmarks, the fix is refreshingly boring: plan less, not smarter.","[\"ai-research\",\"world-models\",\"robotics\",\"model-predictive-control\"]","2026-09-23T04:00:00.000Z","2026-09-23T12:59:30.711Z","2026-09-23T12:59:37.121Z","published",null,[],"ai",[26,27,28,29],"ai-research","world-models","robotics","model-predictive-control",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.23079",0,{"sections":36},[37,41,45,50,55,60,65,70,75,80,85,90,95,100],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",4347,"2026-09-23T12:00:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":18},"Security","security",713,{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",371,"2026-09-23T12:00:43.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",212,"2026-09-23T13:00:46.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",170,"2026-09-23T11:59:23.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Science","science",134,"2026-09-23T09:00:00.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Consumer Tech","consumer-tech",110,"2026-09-22T20:00:00.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Software","software",81,"2026-09-23T09:56:13.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Dev Tools","dev-tools",79,"2026-09-22T22:21:13.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Startups","startups",65,"2026-09-22T22:06:48.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"Gaming","gaming",45,"2026-09-22T15:35:06.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",43,"2026-09-21T23:48:56.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",27,"2026-09-22T13:00:00.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
