In 2023, early adopters were just getting to know ChatGPT and AI chatbot tech. Three years later, OpenAI’s Codex agent, now part of the ChatGPT desktop app, has brought about a similar season of learning. Here’s how I’m using ChatGPT, Codex, and more on my Mac.

In a wide-ranging interview with Joanna Stern, OpenAI president Greg Brockman addressed the company’s recent changes to the ChatGPT desktop app and discussed its plans for a tab-free interface. Watch it below.

OpenAI’s system status page confirms that some users are encountering elevated error rates when trying to use ChatGPT and Codex. Here are the details.

OpenAI is releasing a big update to the ChatGPT desktop app today that introduces GPT Voice mode for talking through work to complete tasks. The new feature is powered by GPT-Live, OpenAI’s upgraded voice mode that arrived on mobile this month.

Last month, OpenAI teased Codex-branded hardware. Today, the company has released its collaboration with Work Louder: a $230 Codex Micro keyboard product.

OpenAI held its second livestream this week today at 10 am PT. The video teased that the company was “introducing the next chapter for ChatGPT” today. OpenAI has openly discussed bringing Codex workflows into the main ChatGPT app for some time now.

Today’s release includes a new ChatGPT Work agent, an upgraded ChatGPT desktop app with Codex included, and a new hosted sites service for OpenAI customers.

OpenAI unveiled GPT-5.6 at the end of June, but the public release was held back while the U.S. government reviewed the new AI models. Now the company has shared an update on when customers will be able to use the upgraded model: this week.

OpenAI just teased an upcoming collaborative hardware project that’s set to launch in July. From the looks of it, OpenAI may be teaming up with a popular keyboard maker to release a Codex-branded input device.

OpenAI is introducing GPT-5.6, its next-generation model, two months after the release of GPT-5.5. However, the rollout to customers won’t be as straightforward as previous model updates to ChatGPT and Codex.

OpenAI is updating ChatGPT with a new scheduled tasks feature. The new ability is rolling out starting today.

At the start of May, OpenAI released a playful feature inside its Codex desktop app for creating a virtual pet.

This silly little addition solved my biggest challenge with Codex: what should I do with it? My first real task with Codex was putting together a virtual Lil Finder Guy for fun.

A month later, I’m using two Mac apps that Codex built at my direction. Toying around with Codex Pets was the gateway for me to better understand its capabilities.

OpenAI continues to push Codex beyond an agentic coding desktop app to a general productivity tool for everyone. As part of that effort, the company shared three enterprise-focused Codex updates today. Additionally, OpenAI says it will soon put Codex functionality inside the ChatGPT app everywhere.

Earlier this month, OpenAI updated ChatGPT’s mobile app to include remote access to Codex for Mac. Starting today, ChatGPT for iPhone and Android can also start work on Codex for Windows as well.

Plus Codex inside ChatGPT for iOS has some new features and improvements.

OpenAI just released this week’s Codex desktop app update, and it includes a brand new feature on Mac called Appshots.

Last week, OpenAI updated ChatGPT for iPhone and iPad with access to Codex, its agentic coding tool for Mac. Since launching, the Codex iOS experience has improved in a few key ways.

OpenAI has released a new way to interact with its Codex app from your smartphone. An update to ChatGPT’s mobile app brings remote access to Codex for Mac to the iPhone, iPad, and Android.

Look, it’s Friday. OpenAI updated Codex. It has Tamagotchi-style pets. You can make your own. Lil Finder Guy is hovering over my Dock.

OpenAI’s GPT-5.5 upgrade to ChatGPT and Codex appears to be going smoothly, especially compared to the rockier GPT-5.0 release last August.

It turns out OpenAI got ahead of one issue that was brewing before the release of GPT-5.5 models: a goblin fixation.

Last week, OpenAI released an all-new version of Codex for Mac that includes the best example of AI-driven computer use yet.

Today, Codex for Mac is taking its recently gained memory feature further with a feature OpenAI calls Chronicle.

OpenAI is releasing a new version of its Codex desktop app today. The latest Codex update adds three key features that expand its use beyond agentic coding.

Today’s release signals the start of a shift for Codex. The app is going from strictly developer-focused to having more general utility as an AI tool on the Mac.
