How ChatGPT Codex appears in this channel ChatGPT Codex shows up in two connected ways in this material: as one of the two sections of OpenAI's newly merged ChatGPT desktop app, and as the surface where the team runs real work — including an informal benchmark consolidating 46 CSV files — to compare models like GPT‑5.5, 5.6, 6, and Fable.[^cb24ef4d-a000-5560-8446-9ed871f58aa8@65] One app, two faces OpenAI combined the separate ChatGPT and Codex desktop applications into a single app with two sections: ChatGPT Work and ChatGPT Codex. As far as the host can tell, they are basically the same thing under the hood — Work hides the code so non-technical people can explore agentic workflows, while Codex presents everything in a more programming-like way.[^f61c605a-a560-515b-8111-60dc76be4fc5@4] Codex in practice In the 46-CSV-file consolidation benchmark, 5.6 in ChatGPT Codex found the right email, reviewed all the data, asked smart clarifying questions, and produced a useful result with minimal intervention — outperforming 5.5, 6, and Fable on the same task. The team connects this to a broader pattern from coding — “I don't do the work alone; I'm building a system that performs work” — spreading into knowledge work, with Codex as one place non-technical people can genuinely run these agentic loops.[^cb24ef4d-a000-5560-8446-9ed871f58aa8@730] - ChatGPT Codex is a section of the merged ChatGPT desktop app, alongside ChatGPT Work. - Both sections are the same engine; Codex simply shows the code in a programming-like presentation. - The channel uses Codex for hands-on model comparisons, including a 46-CSV-file data benchmark. - It is framed as a place where programmer-style agentic loops become available to everyone.
