The agents have to infer hidden policies from the outcomes of their own actions, then adjust again as those policies shift. The benchmark spans 53 separate environment windows and 7,718 tasks, and the team ran 252 learning sessions across 28 model-harness combinations, covering six models - including GPT-5.6 Terra, Opus 5, and DeepSeek V4.1 Flash - and five \"continual learning\" systems such as RAG and Mem0. The results were not flattering: there is a wide gap between what these agents can do on a single task and what they actually absorb from repeated experience.\n\nCompanies pitching AI agents for customer service or sales like to talk about systems that get smarter the longer they run. This research suggests that promise is mostly aspirational. The study also found that on-the-fly adaptation sometimes broke behavior that was already working, and that the agents often failed to explore enough to find the real rules in the first place.\n\nCall it the AI equivalent of a new hire who skips the onboarding doc and somehow gets worse at the job after a month on the floor.","[\"ai-agents\",\"benchmarks\",\"continual-learning\",\"llms\"]","2026-10-08T04:00:00.000Z","2026-10-09T17:07:50.688Z","2026-10-09T17:07:55.693Z","published",null,[],"ai",[26,27,28,29],"ai-agents","benchmarks","continual-learning","llms",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.07792",0,{"sections":36},[37,41,45,50,55,60,64,69,74,79,84,89,94,99],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",6604,"2026-10-09T04:00:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":40},"Security","security",926,{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",486,"2026-10-08T22:40:11.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",474,"2026-10-08T22:00:00.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",229,"2026-10-08T20:47:10.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":40},"Science","science",192,{"name":65,"slug":66,"count":67,"latest_published_at":68},"Consumer Tech","consumer-tech",181,"2026-10-08T23:26:35.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Startups","startups",117,"2026-10-08T16:45:00.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":78},"Software","software",114,"2026-10-08T17:57:01.000Z",{"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",66,"2026-10-09T04:46:11.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"Gaming","gaming",58,"2026-10-08T20:08:45.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",34,"2026-10-08T14:00:22.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
