They scored every configuration with execution-based checks rather than just eyeballing whether the output looked plausible. The result: visible reasoning produced no consistent accuracy advantage, and matching the reasoning's language to the target language did not reliably help either. Effects instead shifted depending on which persona was used, which model ran the test, and how its internal reasoning was configured.\n\nThat undercuts a popular shortcut in prompt engineering - the assumption that showing a model's work, or telling it to think in the target language, is a safe default for coding tasks. For teams building SQL or pandas copilots, the findings argue for tuning reasoning strategy per model and per persona rather than copy-pasting a prompting trick from a blog post.\n\nChain-of-thought's reputation as a free accuracy boost has already taken hits on math and logic benchmarks; this one adds executable code generation to the growing list of places where just add reasoning stops being free advice.","[\"ai\",\"prompt-engineering\",\"code-generation\",\"llm-research\"]","2026-10-09T04:00:00.000Z","2026-10-09T22:57:55.862Z","2026-10-09T22:58:01.865Z","published",null,[],"ai",[24,26,27,28],"prompt-engineering","code-generation","llm-research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.10639",0,{"sections":35},[36,39,43,48,53,57,61,66,71,76,81,86,91,96],{"name":37,"slug":24,"count":38,"latest_published_at":18},"AI",6708,{"name":40,"slug":41,"count":42,"latest_published_at":18},"Security","security",931,{"name":44,"slug":45,"count":46,"latest_published_at":47},"Policy","policy",486,"2026-10-08T22:40:11.000Z",{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",474,"2026-10-08T22:00:00.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":18},"Hardware","hardware",231,{"name":58,"slug":59,"count":60,"latest_published_at":18},"Science","science",192,{"name":62,"slug":63,"count":64,"latest_published_at":65},"Consumer Tech","consumer-tech",181,"2026-10-08T23:26:35.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Startups","startups",117,"2026-10-08T16:45:00.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",114,"2026-10-08T17:57:01.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Dev Tools","dev-tools",105,"2026-10-07T16:59:11.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"General","general",66,"2026-10-09T04:46:11.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Gaming","gaming",58,"2026-10-08T20:08:45.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",34,"2026-10-08T14:00:22.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
