The system can draw on three types of retrieval — lexical (keyword matching), semantic (meaning-based), and multimodal (text plus images) — but unlike conventional pipelines, it decides at each reasoning step which to invoke and how to combine the results. The evolved agent was tested on MMLongBench-Doc and DocBench, two document question-answering benchmarks, where it beat recent systems including MACT, MDocAgent, and SimpleDoc.\n\nThe real finding here is not that mixing retrieval methods helps — that has been known for years — but that the *coordination* of those methods can itself be learned rather than hand-coded. Most production document AI today bakes retrieval order and weighting into the pipeline at design time, which means a single query type that falls outside the designer's assumptions can derail the whole system. A meta-agent that rewrites its own routing instructions is a meaningful step toward systems that generalize without manual tuning.\n\nThe benchmark gains are compelling, but benchmarks are not production document stacks with inconsistent formatting, proprietary file types, and latency constraints — the usual place where research architectures meet their limits.","[\"ai\",\"document-ai\",\"retrieval\",\"multi-agent\"]","2026-06-30T04:00:00.000Z","2026-06-30T11:23:16.689Z","2026-06-30T11:23:19.623Z","published",null,[],"ai",[24,26,27,28],"document-ai","retrieval","multi-agent",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.29648",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,89,94,99],{"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":79},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":86,"slug":87,"count":83,"latest_published_at":88},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
