The teacher gets privileged task information up front, while a separate skill-free student learns from both environment rewards and the teacher's guidance. Rather than following a fixed distillation schedule, the student tracks how close it's getting to the teacher's performance and cuts the teacher loose once the gap stops shrinking and it hits a target fraction of the teacher's success rate, after which training continues with reinforcement learning alone. Tested on Qwen2.5 models from 1.5 billion to 7 billion parameters, the method lifted success rates on the ALFWorld household-task benchmark by 14.1 to 18.8 percent over plain RL, and WebShop shopping-simulation accuracy by 11.8 to 19 percent.\n\nMulti-turn agent training has a stubborn problem: a whole trajectory of actions gets boiled down to one scalar reward, giving the model little to learn from step to step. Distillation from a stronger teacher was supposed to fix that, but the researchers found privileged information doesn't automatically make a teacher trustworthy, and leaning on it too long can cap how good the student becomes. RetireOPD's adaptive cutoff addresses that directly: in every setting tested, the student ended up outperforming the teacher it was trained on.\n\nIt's a preprint, not a peer-reviewed result, and ALFWorld and WebShop are simulated testbeds rather than real deployments. Still, an agent that quietly outgrows its own tutor is a cleaner story than most self-styled reasoning breakthroughs manage.","[\"reinforcement-learning\",\"ai-agents\",\"llm-training\",\"benchmarks\"]","2026-09-18T04:00:00.000Z","2026-09-18T22:55:09.174Z","2026-09-18T22:55:21.087Z","published",null,[],"ai",[26,27,28,29],"reinforcement-learning","ai-agents","llm-training","benchmarks",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.20784",0,{"sections":36},[37,40,44,49,54,58,62,67,71,76,81,86,91,96],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",4082,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",661,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",339,"2026-09-17T12:00:00.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":18},"Hardware","hardware",155,{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",125,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":18},"Dev Tools","dev-tools",78,{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",41,"2026-09-08T01:57:23.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
