NavGPT VLA alone, trained on 19.28 million examples, hits 74.51 percent success on the R2R-CE benchmark and leads RxR-CE at 78.19 percent. Layered with the full reasoning harness, NavGPT-3 pushes R2R-CE to a new high of 81.51 percent and, on RxR-CE, matches human performance: 90.43 percent success versus 90.4 percent for human followers, with similar path accuracy. It does that in 1 minute 22 seconds per episode, against roughly 3 minutes for a person - about 2.2 times faster.\n\nThe real story is the plumbing, not the score. By running reasoning and low-level control as separate, interruptible threads, the system lets slow, deliberate language-model thinking hand off to a fast action policy that reacts in 0.5 to 1 second, instead of the 3 to 19 seconds a pure reasoning loop needs per decision. That is the actual bottleneck holding back language-model-driven robots: not intelligence, but how fast that intelligence converts into motion.\n\nThe numbers come from simulated vision-and-language navigation benchmarks, not a robot wandering a real hallway, so treat human-level as a benchmark claim until it survives contact with an actual building.","[\"robotics\",\"vision-language-action\",\"navigation\",\"benchmarks\"]","2026-10-09T04:00:00.000Z","2026-10-09T23:29:29.650Z","2026-10-09T23:29:35.048Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"The headline claims 'Four Times Faster' while the body says 'nearly three times faster' — neither matches the source math (3:00 vs 1:22 is about 2.2x), so fix the speed comparison consistently throughout using the actual figures.","resolved","ai",[32,33,34,35],"robotics","vision-language-action","navigation","benchmarks",[37],{"name":38,"url":39},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.10787",0,{"sections":42},[43,46,50,55,60,64,68,73,78,83,88,93,98,103],{"name":44,"slug":30,"count":45,"latest_published_at":18},"AI",6708,{"name":47,"slug":48,"count":49,"latest_published_at":18},"Security","security",931,{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",486,"2026-10-08T22:40:11.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Deals","deals",474,"2026-10-08T22:00:00.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":18},"Hardware","hardware",231,{"name":65,"slug":66,"count":67,"latest_published_at":18},"Science","science",192,{"name":69,"slug":70,"count":71,"latest_published_at":72},"Consumer Tech","consumer-tech",181,"2026-10-08T23:26:35.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Startups","startups",117,"2026-10-08T16:45:00.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Software","software",114,"2026-10-08T17:57:01.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Dev Tools","dev-tools",105,"2026-10-07T16:59:11.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",66,"2026-10-09T04:46:11.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Gaming","gaming",58,"2026-10-08T20:08:45.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"Reviews","reviews",34,"2026-10-08T14:00:22.000Z",{"name":104,"slug":105,"count":106,"latest_published_at":107},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
