Rather than just piling up every note, or quietly overwriting old ones, STAM combines semantic retrieval with typed clinical relations to figure out which existing memories a new entry affects. It then sorts information into \"Active\" for current status and \"History\" for anything superseded or resolved, with a query-dependent gate deciding when to surface the historical record. The team tested STAM on four longitudinal clinical benchmarks, measuring both downstream question-answering performance and more direct checks of whether the system tracked state correctly, at roughly matched context lengths.\n\nThis addresses a real, unglamorous problem behind AI-assisted care: an agent following a years-long treatment plan needs to know a drug was discontinued without losing the record of why it was prescribed in the first place. Most memory setups for LLM agents treat memory as either an ever-growing log or a cache that gets evicted, neither of which matches how clinical records actually behave, append-only in principle but state-dependent in practice.\n\nIt's a narrow fix for a narrow failure mode, not evidence that agents are ready to manage care on their own, and the benchmarks here, like most memory research for LLMs, are still a long way from a messy, real electronic health record.","[\"ai\",\"healthcare\",\"llm-agents\",\"research\"]","2026-10-01T04:00:00.000Z","2026-10-01T16:24:28.751Z","2026-10-01T16:24:31.254Z","published",null,[],"ai",[24,26,27,28],"healthcare","llm-agents","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.38490",0,{"sections":35},[36,39,43,48,53,58,62,67,72,76,81,86,91,96],{"name":37,"slug":24,"count":38,"latest_published_at":18},"AI",5487,{"name":40,"slug":41,"count":42,"latest_published_at":18},"Security","security",809,{"name":44,"slug":45,"count":46,"latest_published_at":47},"Policy","policy",429,"2026-10-01T02:26:17.000Z",{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",298,"2026-09-30T21:00:26.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",196,"2026-09-30T13:00:00.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",162,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",149,"2026-09-30T22:57:11.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Dev Tools","dev-tools",93,"2026-10-01T02:30:48.000Z",{"name":73,"slug":74,"count":70,"latest_published_at":75},"Software","software","2026-09-30T21:41:11.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",84,"2026-09-30T20:39:09.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",51,"2026-09-30T16:24:30.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",50,"2026-09-30T21:37:54.000Z",{"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"]
