These models tend to drift: once training exposes the generator to its own imperfect outputs, small errors compound and later frames get worse. The standard fix, called distribution matching distillation, scores a whole generated sequence at once, which can reward a chunk for blending with the increasingly flawed frames around it rather than for actually looking accurate. RMD instead scores each chunk on its own against a separate \"chunk teacher\" model, then runs a second pass of whole-sequence scoring afterward to restore temporal coherence.\n\nThat two-step fix matters because streaming, low-latency video generation is the backbone of any real-time AI video tool, and those tools are only as good as their worst frame five minutes in. According to the paper, RMD keeps visual quality high \"far beyond its training horizon\" and beats prior joint-scoring baselines, which suggests the usual fix for long-video drift has been treating a symptom rather than the underlying cause.\n\nStill, these are lab benchmarks against other research baselines, not a shipped product. \"Outperforms baselines\" is a promising research result - not a promise that your next AI-generated video won't fall apart by the third minute.","[\"video generation\",\"ai research\",\"diffusion models\",\"autoregressive models\"]","2026-09-30T04:00:00.000Z","2026-09-30T17:39:49.770Z","2026-09-30T17:39:56.387Z","published",null,[],"ai",[26,27,28,29],"video generation","ai research","diffusion models","autoregressive models",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.37925",0,{"sections":36},[37,40,44,48,53,58,62,67,72,76,81,86,91,96],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",5183,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",791,{"name":45,"slug":46,"count":47,"latest_published_at":18},"Policy","policy",417,{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",284,"2026-09-29T21:00:00.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",194,"2026-09-29T13:16:04.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",155,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",142,"2026-09-29T18:38:03.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Software","software",91,"2026-09-25T20:55:00.000Z",{"name":73,"slug":74,"count":75,"latest_published_at":18},"Dev Tools","dev-tools",90,{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",83,"2026-09-29T21:51:36.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"General","general",49,"2026-09-28T16:44:57.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
