It covers prompt construction choices and the performance tradeoffs baked into the orchestration layer. The framing is documentation, aimed at developers building on top of Codex or trying to reason about what the agent is actually doing.\n\nPublishing internal architecture details is a developer-relations move as much as an educational one. Coding agents that run shell commands and modify files autonomously need users to trust the loop, and trust tends to follow transparency, or at least a curated version of it. The post also doubles as a working advertisement for the Responses API, OpenAI's stateful multi-turn interface that is quietly displacing older completion endpoints in agentic workflows.\n\nEvery major lab with a coding agent is now publishing \"here is how it works\" content. Whether that builds genuine understanding or just builds brand is a fair question to keep asking.","[\"openai\",\"codex\",\"ai-agents\",\"developer-tools\"]","2026-01-23T12:00:00.000Z","2026-06-16T08:39:59.879Z","2026-06-19T13:15:45.285Z","published",null,[24,30],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Add a brief concluding paragraph that summarizes the news and its significance, giving the article a clear ending.","resolved",{"id":31,"reviewer":26,"round":32,"reason":28,"status":29},"editor-r2",2,"dev-tools",[35,36,37,38],"openai","codex","ai-agents","developer-tools",[40],{"name":41,"url":42},"OpenAI","https:\u002F\u002Fopenai.com\u002Findex\u002Funrolling-the-codex-agent-loop",0,{"sections":45},[46,51,56,61,66,71,76,81,86,90,95,100,105,110],{"name":47,"slug":48,"count":49,"latest_published_at":50},"AI","ai",2602,"2026-07-18T18:30:00.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Security","security",315,"2026-07-17T19:30:00.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Policy","policy",169,"2026-07-17T19:49:53.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Hardware","hardware",126,"2026-07-16T20:09:48.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Consumer Tech","consumer-tech",94,"2026-07-16T16:29:46.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",72,"2026-07-17T09:42:05.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":87,"slug":33,"count":88,"latest_published_at":89},"Dev Tools",60,"2026-07-16T16:59:13.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Startups","startups",42,"2026-07-16T16:30:35.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":106,"slug":107,"count":108,"latest_published_at":109},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":111,"slug":112,"count":113,"latest_published_at":114},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
