These are the type of details that matter. Time saved in critical workflows compounds.

[Blaida @kedytcom]

OpenAI just killed the worst part of building iOS apps with AI.

The new Codex "Build iOS Apps" plugin can now:

→ run your app in an in-app browser
→ open SwiftUI previews
→ hot reload edits

all without leaving Codex.

No more copy-paste-build-screenshot loop. The agent sees what it ships.

This is the loop indie devs have been begging for.

[Kevin Kaiser @kyza____]

Working with the iOS Simulator in-app is a big deal. Can’t wait to try this.

[OpenAI Developers @OpenAIDevs]

More of the iOS app loop, now inside Codex.

The Build iOS Apps plugin lets Codex view and test your iOS app in the in-app browser, open SwiftUI previews, and hot reload edits without leaving Codex.

Rare air

Standing on the brink of history.

[Kevin Kaiser @kyza____]

It's even sweeter when the road to get there was long

[Arsenal @Arsenal]

This belongs to all of us.

Done ✅

Token maxi.

Running Codex from my phone while on public transit

[Kevin Kaiser @kyza____]

I have to say it again. Computer use in Codex is incredible.

I'm building up an app with multiple third party services. After registering an account for each service, I can hand it off to Codex to connect them all together -- even when they don't have Plugins or MCPs available.

You've been asking for this one...

Now in preview: Codex in the ChatGPT mobile app.

Start new work, review outputs, steer execution, and approve next steps, all from the ChatGPT mobile app. Codex will keep running on your laptop, Mac mini, or devbox.

hmm computer use looks like it burns tokens fast

[Kevin Kaiser @kyza____]

Codex with computer use is a game changer.

You're no longer restricted to using apps with plugins/MCPs. Codex can use any app on your computer.

[Kevin Kaiser @kyza____]

Codex/Claude plugin maxi.

If your app doesn't have a good plugin/MCP/CLI I don't want it.

Migration products are excellent growth hacks

We will stop requesting specific solutions and we will instead ask to solve problems

[TBPN @tbpn]

OpenAI member of product staff @embirico describes the evolution of "Lord Bottleneck," an internal Codex loop developed by a single staff member that ultimately ended up creating a tight feedback and improvement loop for new user experiences:

"This person on the growth team needed to figure out what experiments to run. And they needed to write code to run the experiment. Then they needed to analyze the experiment."

"They started using Codex for each separate thing. So they had it run a bunch of analyses, interrogate the data, talk to Codex about the data. Then they would pick an experiment, and ask Codex to write the code. Then they would run the experiment, then ask Codex what the results of the experiment were. Then they would produce a deck."

"All steps they were doing individually. They didn't start by saying, 'I'm going to automate this entire thing,' because that's hard and scary. They just started with using Codex to accelerate themselves."

"Then, they started connecting all these things together into a giant skill. And one day, they just said [to Codex], 'Why don't you do this every morning?'"

"They gave it a name: 'Lord Bottleneck.' Because it's solving the bottlenecks of friction for new users."

"Now, every morning, Lord Bottleneck evaluates past experiments, looks at data, proposes some [new] experiments, and offers to the team to run the experiments. The team picks [what experiments to do]. Then Lord Bottleneck is like, 'Ok cool. Here's some code or whatever config that needs to be done,' runs the experiment, and they go and do the same loop the next day."

"It's really serious value. I forget the numbers, but it's produced significant company value automatically through Codex."

[Kevin Kaiser @kyza____]

I've been very impressed by Codex's performance on UX design with GPT-5.5.

Instead of telling Codex to execute specific design implementations, I've been using it as a thought partner, requesting recommendations based on best practices.

As a result, I spend less time thinking about solutions and more time describing problems for Codex to solve.

[Kevin Kaiser @kyza____]

Onboarding at a new job via AI with comprehensive connectors to internal documentation, communication channels and data sources is insane. You can learn in 1 week alone what would have taken weeks and many meetings previously.

Anthropic is crushing it. No software company is safe.

[Claude @claudeai]

Introducing Claude Design by Anthropic Labs: make prototypes, slides, and one-pagers by talking to Claude.

Powered by Claude Opus 4.7, our most capable vision model. Available in research preview on the Pro, Max, Team, and Enterprise plans, rolling out throughout the day.

Codex can use your computer while you’re using it for something else 🧠

[Aakash Gupta @aakashgupta]

OpenAI quietly solved the single problem that's been blocking computer-use agents from going mainstream: the cursor war.

Anthropic shipped computer use in October 2024. OpenAI shipped Operator. Google shipped Mariner. All three hit the same wall. When the agent moves the cursor, you can't. The screen is one resource, and two drivers cannot share it. Every demo ended the same way: "run this while I go get coffee."

That kills the ROI math. If the human has to stop working to let the agent work, the agent is functionally a replacement. Adoption of computer-use agents flatlined at power users and scripted demos for exactly this reason.

Here's what OpenAI actually shipped. Codex runs multiple agents against your real Mac apps, in parallel, with their own cursors, in the background, while you keep using your machine. The mechanism is OS-level sandboxing. OpenAI acquired Sky Applications last fall. That's the team that built Workflow, which became Apple Shortcuts. They spent a decade figuring out how to let third-party code drive other Mac apps without breaking the foreground experience. OpenAI didn't buy a team. They bought the only people on Earth who had solved this.

The economic unit of white-collar work just changed. Yesterday the ceiling was one human with one agent doing one task. Today it's one human supervising five agents working across five apps the human is simultaneously using. The bottleneck stops being compute. It becomes the human's ability to review output.

Codex has 3M weekly devs. The feature that matters is not the IDE. It's that OpenAI turned the Mac into a multiplayer instrument.

[Kevin Kaiser @kyza____]

In a world where more people are developers, enterprise software will increasingly rely on referrals from coding agents to acquire customers.

Below is an example of Codex telling me to use @resend to send my app's emails. This is how @supabase took off.

Even previously non technical software buyers like the marketing department will be using a coding agent to select and deploy their GTM suite.

If you build the most agent friendly software, you can own the primary distribution channel of the future.

Everyone should be using the desktop app from one of the leading AI labs to control their computer.

These tools are not just for developers. You no longer need to learn how to use every app on your computer or every website in your browser. Just tell your desktop AI app what you need.

[OpenAI @OpenAI]

Codex for (almost) everything.

It can now use apps on your Mac, connect to more of your tools, create images, learn from previous actions, remember how you like to work, and take on ongoing and repeatable tasks.
