"I asked AI to write a TODO app. It wrote a TODO app that generates more TODO apps. Now I'm stuck in an infinite loop of productivity."

What's up builders 👋

OpenAI just dropped a bomb at DevDay - you can now build apps that live inside ChatGPT conversations. Not plugins, not extensions - actual interactive apps.

Meanwhile, the vibe coding debate is getting spicy with wired calling it "the new open source in the worst way possible" while a16z data shows startups are throwing serious cash at these tools. Let's dive into what's shipping, what's breaking, and what you can actually build with all this new stuff.

🔥 Today's Top Story

At DevDay 2025, OpenAI announced that developers can now build apps that run directly inside ChatGPT conversations. Not browser extensions, not plugins - actual interactive applications that users can chat with.

Instead of context-switching between ChatGPT and your tools, everything happens in one conversation thread. OpenAI's announcement shows apps handling everything from data visualization to API calls, all while maintaining conversational context. The technical implementation uses a new framework that lets your app receive messages, process them, and respond with rich UI components.

Plus they also released,

AgentKit – OpenAI's Answer to n8n Drag-and-drop agent builder for deploying AI workflows. The question: Will this actually stick, or go the way of CustomGPTs?

Sora-2 & GPT-5-Pro Both now available via API at reasonable pricing. Early reports suggest Sora-2 API has no watermark (can anyone confirm content restrictions?).

Codex Suite – Now Generally Available Full AI coding toolset with Slack integration and team admin features. Worth exploring if you're shipping code with AI assistance.

The bottom line: OpenAI just consolidated a lot of the AI tooling stack. Some startups just got their runway cut short. Others found their distribution channel.

One More Thing...

OpenAI just turned ChatGPT into an operating system. Think about it - 800 million weekly users, apps running inside conversations, and developers can now reach users without app stores, downloads, or onboarding. We're watching the birth of a new platform economy, except this time the platform speaks human.

The vibe coding backlash is hilarious though. WIRED's calling it "open source in the worst way" while a16z data shows startups are betting their runway on these tools. Maybe both are right? We're speed-running software development but nobody knows if the code will work in six months.

Keep shipping,

P.S. - Saw someone use ChatGPT Apps to build a ChatGPT app that builds ChatGPT apps. We've reached peak recursion. Time to go home, everyone.
