The system studies its own past attempts, called experience traces, and edits those instructions based on what worked and what did not. A companion method, EMHO-Merge, lets a single harness serve multiple tasks, like navigation and object manipulation, without a fix for one job breaking another. Tested on the EmbodiedBench benchmark, EMHO improved task success for both a 9-billion and a 27-billion parameter version of the Qwen model.\n\nThat is a different lever than the usual one. Most efforts to improve AI agents pour money and compute into bigger models or more training data. EMHO bets that a frozen, off-the-shelf model can perform much better if the instructions wrapped around it are sharper, and that an agent can write those sharper instructions itself by reviewing its own mistakes.\n\nThe paper does not publish actual success-rate numbers in its abstract, so it is hard to say how big a jump this really is, or whether it holds up outside EmbodiedBench's own test tasks.","[\"ai agents\",\"embodied ai\",\"robotics\",\"research\"]","2026-10-07T04:00:00.000Z","2026-10-08T22:56:19.816Z","2026-10-08T22:56:24.914Z","published",null,[],"ai",[26,27,28,29],"ai agents","embodied ai","robotics","research",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.08432",0,{"sections":36},[37,41,46,51,56,61,66,71,76,80,85,90,95,100],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",6448,"2026-10-07T18:45:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",904,"2026-10-07T19:53:42.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Policy","policy",474,"2026-10-07T18:23:21.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",453,"2026-10-07T23:58:31.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",222,"2026-10-07T21:19:54.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Science","science",186,"2026-10-06T21:20:39.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",174,"2026-10-07T17:41:41.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",113,"2026-10-07T18:10:00.000Z",{"name":77,"slug":78,"count":74,"latest_published_at":79},"Startups","startups","2026-10-07T23:36:57.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Dev Tools","dev-tools",105,"2026-10-07T16:59:11.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"General","general",61,"2026-10-07T22:00:24.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Gaming","gaming",56,"2026-10-07T12:00:00.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",33,"2026-10-05T11:57:17.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
