the chat app and the coding agent finally share one window. openai's new chatgpt desktop app, out globally on macos and windows, merges chat, work agents and codex, lets work touch local files and a built-in browser, and ships codex in the same app.
the terminal agent became a desktop product.
Context
OpenAI's post of 9 July 2026 says the updated ChatGPT desktop app is available globally for Mac and Windows with Chat, Work and Codex, that on desktop ChatGPT can use local files and apps and has a built-in browser, and that the Codex app is merging with the new ChatGPT desktop app. OpenAI's help article says the new app includes Chat and Work alongside Codex, that ChatGPT Classic remains, and that Codex is not selectable on web or mobile. The release notes confirm that on 9 July the Codex app merged into the ChatGPT desktop app for macOS and Windows.
The launch is 9 July 2026, about ten weeks before the note's date, so new and finally are the note's framing. The Codex CLI and IDE extension still exist, so the terminal agent became a desktop product is the author's characterisation, and that the chat app and the coding agent merged is the author's thesis.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
