The benchmark builds relation-controlled memory variants - complementary, nuanced, and contradictory versions of the same underlying fact - and buries them inside realistic, long-running user-agent conversation histories. It totals 1,522 evaluation instances across 10 long histories, built from 1,090 relation-controlled memory-variant sets, covering both user-specific and general queries. The team tested six standalone memory systems plus five Claw-style agents, two with native memory modules and three running plugin memory add-ons, and found that nearly all of them struggled to tell the memory relationships apart correctly.\n\nMost memory benchmarks check whether an agent can recall a fact, not whether it still understands how that fact fits with everything else it has been told. That gap matters as assistants get pitched as long-term collaborators: a scheduling assistant that misses the fact that your new no-meetings-before-10am note contradicts what you said last month isn't just forgetful, it is actively wrong. The researchers' diagnostic protocols go further, separating failures by stage - whether a system drops the relevant detail when storing memories, fails to retrieve it, or retrieves it but reasons about it incorrectly - which is useful for anyone trying to figure out where their own memory stack actually breaks.\n\nPersistent memory has been pitched as the next big unlock for AI assistants for a couple of years now. This benchmark is a reminder that storing more memories isn't the hard part, keeping them straight is.","[\"ai agents\",\"long-term memory\",\"benchmarks\",\"research\"]","2026-10-07T04:00:00.000Z","2026-10-09T03:56:06.552Z","2026-10-09T03:56:10.794Z","published",null,[],"ai",[26,27,28,29],"ai agents","long-term memory","benchmarks","research",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.05761",0,{"sections":36},[37,41,46,51,56,61,65,70,75,79,84,89,94,99],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",6516,"2026-10-07T18:45:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",911,"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":18},"Science","science",187,{"name":66,"slug":67,"count":68,"latest_published_at":69},"Consumer Tech","consumer-tech",174,"2026-10-07T17:41:41.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Software","software",113,"2026-10-07T18:10:00.000Z",{"name":76,"slug":77,"count":73,"latest_published_at":78},"Startups","startups","2026-10-07T23:36:57.000Z",{"name":80,"slug":81,"count":82,"latest_published_at":83},"Dev Tools","dev-tools",105,"2026-10-07T16:59:11.000Z",{"name":85,"slug":86,"count":87,"latest_published_at":88},"General","general",61,"2026-10-07T22:00:24.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"Gaming","gaming",56,"2026-10-07T12:00:00.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",33,"2026-10-05T11:57:17.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
