Cortex attacks that problem by inserting a structured interface between a high-level Vision-Language Model that plans and a low-level VLA that moves. The team codified manipulation into 32 canonical skill primitives and used that vocabulary to annotate more than 4,000 hours of open-source video and generate 30 hours of simulation data. An event-balanced sampling strategy helps the system handle the messy transitions between subtasks, where ambiguity tends to pile up.\n\nThe numbers are modest but meaningful: Cortex beats monolithic baselines by 3.1% on the Libero-long benchmark and 4.1% on RoboTwin. More interesting is the zero-shot result — the generalist planner completed multi-stage chemistry experiments it had never seen before, simply by pairing with a fine-tuned VLA. That's a capability the researchers say is out of reach for VLA fine-tuning alone.\n\nThe dual-system approach is not new — hierarchical planners have been a robotics staple for years — but the coordination gap between planning and execution has always been the hard part. Cortex's contribution is essentially a cleaner translation layer, and whether that holds up outside tidy lab benchmarks is the question every robotics paper has to answer eventually.","[\"robotics\",\"ai\",\"machine-learning\",\"research\"]","2026-07-07T04:00:00.000Z","2026-07-07T15:32:07.193Z","2026-07-07T15:32:09.236Z","published",null,[],"ai",[26,24,27,28],"robotics","machine-learning","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.05377",0,{"sections":35},[36,40,45,50,55,60,65,70,75,79,84,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":18},"Dev Tools","dev-tools",59,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
