On classification tasks, adding explanations to few-shot prompts usually beat plain few-shot prompting, and externally generated LLM explanations held up about as well as human ones when both were available. Self-generated explanations were shakier: their usefulness depended heavily on which examples got selected. Math reasoning tasks did not follow a clean pattern - results varied by model and by where the explanation came from.\n\nThis is a useful gut check for anyone building prompting pipelines that lean on chain-of-thought or rationale examples: cheap, LLM-written explanations are apparently not a downgrade from human-authored ones, at least for classification work. It also complicates the popular idea of filtering self-generated explanations for faithfulness before using them - the paper found different faithfulness metrics disagree with each other, so the filter you pick can help or hurt depending on the task.\n\nIn other words, before a pipeline swaps in a model's own explanation of itself as a training aid, it is worth asking which faithfulness metric is being trusted and why - the paper suggests that answer is not settled.","[\"ai\",\"in-context-learning\",\"llm-research\",\"prompting\"]","2026-08-18T04:00:00.000Z","2026-08-18T21:37:37.185Z","2026-08-18T21:37:49.071Z","published",null,[],"ai",[24,26,27,28],"in-context-learning","llm-research","prompting",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.16627",0,{"sections":35},[36,40,44,49,54,59,64,69,74,78,83,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":39},"Security","security",435,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"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":58},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":18},"Dev Tools","dev-tools",69,{"name":79,"slug":80,"count":81,"latest_published_at":82},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
