It comes in two flavors: a bidirectional version for full-context generation, and a causal version built for real-time, streaming use, both based on the existing Wan2.2-TI2V-5B model. A camera-encoding technique called PRoPE feeds in intrinsics and extrinsics, and a 64-dimensional action stream runs through every layer of the transformer. Getting there took five training stages: teaching bidirectional camera and action control, converting the backbone to block-causal attention, distilling a fast few-step student model, restoring dynamics across mixed domains, and a final asymmetric DMD\u002FDMD2 distribution-matching pass.\n\nThe causal model renders 832x480 video at 24 frames per second and streams in real time on a single Nvidia L20 GPU - training the whole pipeline took just two of those cards. On the WBench Full benchmark it scored 70.0, beating the 13.6-billion-parameter LongCat-Video and 14-billion-parameter Helios, landing within a point of the 22-billion-parameter LTX-2.3, and edging out YUME 1.5, a rival trained from the same 5B base model but on Nvidia A100 GPUs instead. That is a genuine efficiency result, not just a bigger-number one, and the reserved action interfaces mean it is built to be fine-tuned for robotics and self-driving work later.\n\nBenchmark scores are not the same as a robot avoiding a wall, and open weights matched to real-time speed is exactly the combination every ambitious world-model launch promises but few actually deliver.","[\"ai\",\"world-models\",\"open-source\",\"video-generation\"]","2026-09-18T04:00:00.000Z","2026-09-18T20:50:24.062Z","2026-09-18T20:50:35.976Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"The body claims a 'five-stage training pipeline' but only enumerates four stages (camera and action control, causal conversion, student distillation, dynamics restoration), omitting the fifth stage from the source (asymmetric DMD\u002FDMD2 distribution matching) — fix the count or list all five stages.","resolved","ai",[30,32,33,34],"world-models","open-source","video-generation",[36],{"name":37,"url":38},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.20034",0,{"sections":41},[42,45,49,54,59,63,67,72,76,81,86,91,96,101],{"name":43,"slug":30,"count":44,"latest_published_at":18},"AI",4066,{"name":46,"slug":47,"count":48,"latest_published_at":18},"Security","security",657,{"name":50,"slug":51,"count":52,"latest_published_at":53},"Policy","policy",338,"2026-09-11T04:00:00.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":18},"Hardware","hardware",155,{"name":64,"slug":65,"count":66,"latest_published_at":18},"Science","science",123,{"name":68,"slug":69,"count":70,"latest_published_at":71},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":73,"slug":74,"count":75,"latest_published_at":18},"Dev Tools","dev-tools",78,{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"General","general",41,"2026-09-08T01:57:23.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":102,"slug":103,"count":104,"latest_published_at":105},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
