Users who attempt to download Codex now receive ChatGPT instead, which mixes personal and work chats with no option to run in Codex mode. The change has disrupted workflows for developers who relied on Codex's separate environment.", "body_md": "Hi HN. Today Codex (macOS) prompted to upgrade, and it failed - the app is gone, but was not replaced. The dock icon shows a question mark.\n\nTo fix this I tried to download the Codex app from OpenAI. https://developers.openai.com/codex/app redirects to ChatGPT. The Codex page itself (https://openai.com/codex/) talks about 'now in ChatGPT' and prompts to download.\n\nSure enough, downloading what appears to be Codex downlaods ChatGPT -- and so opening 'Codex' loads all my personal chats, non-work conversations, etc.\n\nI cannot emphasise enough how much this is a disaster. I cannot mix my personal and work use - not least just for keeping them separate (I do *not* want to see personal chats while working.)\n\nThe OpenAI claim seems to be that you can run it in Codex mode? Yet there is *zero* UI for this. ChatGPT claims it's got the latest installed. Currently my entire Codex workflow is gone.\n\nSome form of Codex is still available via GitHub releases, latest here: https://github.com/openai/codex/releases/tag/rust-v0.144.3 but I cannot find the app itself. There is the CLI, the app server... 163 different downloads, but no macOS Codex app.\n\nComments URL: [https://news.ycombinator.com/item?id=48890384](https://news.ycombinator.com/item?id=48890384)\n\nPoints: 1\n\n# Comments: 1", "url": "https://wpnews.pro/news/tell-hn-the-codex-app-is-replaced-by-chatgpt", "canonical_source": "https://news.ycombinator.com/item?id=48890384", "published_at": "2026-07-13 10:12:59+00:00", "updated_at": "2026-07-13 10:35:49.577225+00:00", "lang": "en", "topics": ["ai-products", "developer-tools"], "entities": ["OpenAI", "Codex", "ChatGPT"], "alternates": {"html": "https://wpnews.pro/news/tell-hn-the-codex-app-is-replaced-by-chatgpt", "markdown": "https://wpnews.pro/news/tell-hn-the-codex-app-is-replaced-by-chatgpt.md", "text": "https://wpnews.pro/news/tell-hn-the-codex-app-is-replaced-by-chatgpt.txt", "jsonld": "https://wpnews.pro/news/tell-hn-the-codex-app-is-replaced-by-chatgpt.jsonld"}}
