Anyone from Claude Code team around? When using Codex, I rely heavily on having one thread orchestrate others. It can create new threads, rename them, delete them, and coordinate work between them. I can also use side chats to send messages to the main thread or any other thread. Effectively, the possibilities for coordinating work across threads are almost endless. But the Claude Code's desktop app, is extremely limited by comparison, to the point where I can only use Claude for relatively basic tasks. Then there's the issue of keyboard shortcuts. For some reason, Claude seems to have an aversion to macOS keyboard conventions. I can't even assign a shortcut to something as simple as renaming or pinning a thread. Instead, I have to use the mouse to right-click a thread and then press a single key to trigger a menu command. It's an extremely bizarre design choice, especially for a developer tool. I've heard great things about Opus 5.5, and I'd love to take full advantage of it. But the Mac app is so limited that I simply can't use the service anywhere near its full potential.

I’ve started to write a little bit on my page thaliaeche.is/iconic. I’ll make sure to write a bit more and I’ll think about some talks. Let me know if you want any topic in particular 😊

Best icon designer of our times! Thalia did all the SF Symbols you love, and now is making beautiful icons at OpenAI!
Seeing the little icons I’ve designed in ChatGPT never gets old. My little contribution to something much bigger, one tiny icon at a time. 🥹

Today I am open-sourcing my custom SwiftUI animation sequencing package that I developed to drive the animations in Letters. It can do all sorts of things! github.com/jazzychad/Animati…

Today, I'm sharing Milepost! It's a driving journal on iOS that lets you record your drives, cars, music, photos, and more. You can share them with friends, get monthly recaps, and even let agents recommend routes with our MCP server. Download it here → milepost.club/

The new Codex prompt prediction thing really does feel spooky. Would love to know how it can be so accurate.

What a great way to demo the problem with textual outputs and the benefits of a visual richer response! I've been super interested in this space and building towards something similar lately. 😄
GPT-6 and Intelligent UI, now rolling out in ChatGPT for everyone. Intelligent UI in ChatGPT delivers fast, interactive answers that make everyday questions more visual, complex topics easier to grasp, and interactive tools for your task available on the spot.

I gave Opus 5.5 one prompt + music. 12 hours later, I woke up to this.

There's an open-source SwiftUI agent skill that catches the mistakes AI tools keep making: deprecated modifiers, accessibility gaps, performance pitfalls. One command to install, and your AI-generated SwiftUI gets a serious quality boost. hackingwithswift.com/article…

I’ve been thinking about this often. You can certainly copy a lot from using it, but there’s often a lot of secret sauce under the hood that is not exposed and the details still matter. Otherwise, active engagement, etc probably count more than ever.
This is such a fascinating time for AI companies in terms of strategy: The cost to copy is zero, the speed of copying is days/weeks, and thus basically everyone is converging on building the same thing (eg dot, muse, instinct, etc) wtf do you do? who wins and why?

How does one find a cofounder for a company. The YC founder match is not really great. Thinking of starting something in the consumer space, iOS, chat bot. Ideally someone who has some experience with startups.

I accidentally said it was the wrong date to an agent, ad it made up a bunch of futuristic 2206 iPhone settings. "If you recently traveled via sub-orbital shuttle or wormhole commuter line"

Duo-Man offers the complete walkman experience on the iPhone Duo. Open the Duo to pick and 'insert' the cassette, Close the Duo to start listening. Yes, I actually recorded the button clicks and static noise from a real Walkman! It was fun making this at @bitrig hacks today.

Having now spent enough time with both Fable and Astra, here's how I've found Codex and Claude compare for app development, along with some tips for success 👇
