The real test for OpenAI Marketplace: can an independent developer build a business here? Discovery, paying users, recurring revenue. Is this finally the pot of gold for builders—or another rainbow? 🌈 @OpenAIDevs

More sleepless nights ahead.
We're extending Claude Fable 5 access on all paid plans, as well as keeping Claude Code’s weekly rate limits 50% higher, through July 19.

Great having you @gokulr at the Jamaican AI Hackathon. Your message was clear: build autonomous agents, not traditional software. The session was a huge hit with the attendees.

A packed room of 2,000+ AI builders at the @intelli_bus Jamaican AI Hackathon. The vision: help Jamaica 10× its GDP in the next 10–15 years. Massive energy. Serious talent. 🇯🇲

It looks chaotic right now. That’s usually what convergence windows look like from the inside. This isn’t about one breakthrough. It’s about multiple constraints easing at the same time. GPUs and accelerated computing are no longer niche. They’re becoming the default substrate for serious workloads. AI algorithms are improving in efficiency, not just scale. Better architectures. Better training methods. Better inference. Energy is now a first-order design constraint. That’s a good thing. It forces real systems thinking instead of brute force. Space exploration is shifting from novelty to infrastructure. Launch cadence is up. Costs are down. Integration is improving. These advances compound. Compute enables better models. Better models demand better energy systems. Energy constraints reshape hardware and software together. This is how platforms form. Convergence windows don’t feel stable while you’re inside them. They feel noisy. You only recognize them later. This one is open now.

Congrats @OpenAI on GPT‑5! Quick takeaways from the livestream: 1️⃣ Single model auto‑picks the best approach—no more model juggling. 2️⃣ Gmail & Google Calendar integration = real personalization. 3️⃣ UI is next‑level; I’ve never seen this polish with previous models.

Tesla Robotaxi is finally active in testing status after years of waiting! I’ve been looking forward to this day since 2016—ever since I let the steering wheel go for the first time.🤞 txdot.maps.arcgis.com/apps/d…

Here’s how to get started with Codex:
We’re launching a research preview of Codex: a cloud-based software engineering agent that can work on many tasks in parallel. Rolling out to Pro, Enterprise, and Team users in ChatGPT starting today. chatgpt.com/codex

I’m *really* trying to play it cool here but like… I’mma just say it: Codex might be the most impressive, most *powerful* AI product I’ve ever touched. all things considered. the async ability, especially, is on another level. like it’s not just a technical ‘leap’, it’s **transcendent**. I’ve used basically every ai coding tool and platform out there at least once, and nothing else is in the same class. it just **works**, ridiculously well. and I’ll admit, I didn’t want to like it. Maybe it’s stubborn loyalty to Claude - I love that retro GUI and the no-nonsense simplicity of Claude Code. There’s still something special there and ill alway use it. but, if I’m honest: that edge is kinda becoming irrelevant, because Codex feels like having a private, hyper-competent swarm - a crack team of 10/10 FS devs, but kinda *better* i think tbh. it’s wild. at this rate, I might start shipping something new every single day, at least until I clear out my backlog (which, without exaggeration, is something like 35-40 ‘projects’ that are all ~70–85% done). this could not have come at a better time too. I desperately needed the combination of something like codex and much higher rate limits + a streamlined pipeline from my daily drive ai to db. go try it out. sidebar/tip: if you cant get over the initial hump, pop over to ai . studio . google . com and click the “build apps” button on the left hand side. a bunch of sample apps and tools propogates and theyre actually really really really good one-click zero-shots essentially…. shits getting wild. and its only monday.
Codex is now available in the ChatGPT iOS app! Start new tasks, view diffs, ask for changes, and even push PRs—all on the go. And you can keep tabs on Codex with live activities on your lock screen, or pick things up again when you're back at your computer. 🏃🤳

In my experience, Codex is poised to initially automate a range of discrete, long-tail programming tasks—testing, bug fixes, and to-dos. Looking ahead, as GenAI scales, it increasingly resembles AGI tailored for software engineering. every.to/chain-of-thought/vi…
