Orchestration overhead alone multiplied latency by more than 60x in some frameworks, and a stripped-down version of the same coordination approach showed that cost came from sloppy implementation, not the approach itself. Forcing agents to output rigid, schema-constrained plans cut accuracy by up to 32 points - and the errors traced back to formatting failures, not bad reasoning. Mismatched communication topology dropped coordination success from above 90% to below 30%, and memory design controlled how well agents recalled information regardless of context window size.\n\nThat's a useful correction for anyone shopping for a multi-agent framework by which foundation model it's built on. The bigger predictor of whether a system holds together is how it's wired: who talks to whom, how state gets passed around, and how rigidly agents are told to format their output. It's the same lesson distributed systems learned decades ago - the protocol matters as much as any single node.\n\nWorth noting: none of the nine frameworks tested could cleanly update what an agent already knows, so even the best-wired setup still can't un-teach a bad memory.","[\"ai\",\"multi-agent-ai\",\"llm-benchmarks\",\"software-architecture\"]","2026-09-18T04:00:00.000Z","2026-09-19T07:37:44.826Z","2026-09-19T07:37:56.744Z","published",null,[],"ai",[24,26,27,28],"multi-agent-ai","llm-benchmarks","software-architecture",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2602.03128",0,{"sections":35},[36,40,45,50,55,60,65,70,74,79,84,89,94,99],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",4114,"2026-09-19T18:33:46.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",673,"2026-09-19T17:30:00.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",345,"2026-09-19T19:22:20.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",156,"2026-09-19T11:00:00.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Science","science",129,"2026-09-19T19:45:00.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":18},"Dev Tools","dev-tools",78,{"name":75,"slug":76,"count":77,"latest_published_at":78},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":80,"slug":81,"count":82,"latest_published_at":83},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":85,"slug":86,"count":87,"latest_published_at":88},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",42,"2026-09-18T22:35:10.000Z",{"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"]
