OpenAI's official ChatGPT app for macOS is now available to all users for the first time, provided they're running macOS Sonoma or later.
It was previously being rolled out gradually to paid subscribers to ChatGPT's Plus premium plan.
The ChatGPT Mac app mostly acts as a desktop window version of the web app, allowing you to carry on back-and-forth prompt-and-response conversations. You can select between the GPT-3.5, GPT-4, and GPT-4o models. It also supports the more specialized GPTs available in the web version, including the DALL-E image generator and custom GPTs.
There is one important omission in this desktop app: It doesn't support using the API. For that, those wanting a desktop app will still need to use a third-party one like Jordi Bruin's MacGPT.
OpenAI's app lets you enable a system-wide keyboard shortcut (option + space by default) to type in a prompt any time; it works a bit like opening a Spotlight search in macOS.
The ChatGPT app was announced alongside the GPT-4o model, which is faster and cheaper to use than GPT-4 with similar (albeit not exactly the same) accuracy and quality; GPT-4o also has an expanded ability to interact with images and videos.
