Last week, OpenAI updated ChatGPT for iPhone and iPad with access to Codex, its agent coding tool for Mac. Since its launch, the Codex iOS experience has improved in several key ways.
Here’s what’s new in Codex in ChatGPT for iPhone and iPad this week
For starters, when Codex in ChatGPT launched on iOS, there was a frustrating bug that prevented OpenAI accounts that use Sign in with Apple from setting up the feature.
OpenAI has since fixed the issue that caused the app to display a Google login form incorrectly.
If you’re using Sign in with Apple for your OpenAI account and you weren’t able to link the Codex initially, try again.
In terms of features, Codex in ChatGPT added support for push notifications for round completion.
This means you can be alerted on iPhone or iPad when a task on Codex for Mac is completed or asks for input. No need to track progress.
OpenAI has also added support for more commands, starting with /fork and /side is on the way.
Looking ahead, we’ll likely see new features and capabilities coming to the Codex desktop app later today. OpenAI has been regularly updating the Codex with larger feature releases on Thursdays for the past few weeks.
Codex for Mac is available here and ChatGPT is on the App Store.
The Codex is quickly becoming the advanced user version of ChatGPT
Last month, Codex on Mac gained the ability to use applications on your computer without taking control of the cursor. This means you can use Codex to run tasks on your Mac without giving up the ability to use your machine at the same time.
In addition to improving the Codex desktop application, OpenAI recently introduced a subscription designed for Codex users. OpenAI also released GPT-5.5, upgrading the capabilities of ChatGPT and Codex, alongside Images 2 for image generation.
Codex only came to Mac in February after starting out as a command-line interface tool.
