@thsottiaux Long day, just catching up here. Wasn’t this just 7M yesterday?

Hello. We have reached 8M active users across Codex and ChatGPT Work. We are once again resetting the usage limits for all. And we continue to not have the 5h rate limit as well, allowing everyone to explore the boundaries of GPT-5.6 Sol and discover how ambitious you can be. See you tomorrow for more updates on our growth!

@prasenx @elshayib_ So close, upside down and backwards.

@elshayib_ I told it to right hello 🙂

just asked gpt-5.6 sol in cursor to set up blender mcp and make me a realistic floating macbook, then render the whole thing. never opened blender once in my life before today.

@ChrisJBakke CDRW 🔥

Data centers? No thanks. I’m running my entire company on a Never Obsolete eMachines eTower566

GPT-5.6 sol beats Fable 5 on most published benchmarks at less than half the cost openai played this perfectly anthropic either sticks to its plan of making fable api-only on the 12th or pivots again and looks foolish, possibly keeping it on the subscription at full usage instead of 50%

OH: AGI is when you can ask a Slack bot who’s dating at the office and it gives you the right answer.

The new ChatGPT Work comes with a new Computer Use experience. It's faster and introduces picture-in-picture, so you can keep an eye on Computer Use while it works!

Very supportive of this decision.

@jxnlco Vehicle registration, drivers license address change, HSA reimbursements from emailed receipts and Amazon refunds.

if you use codex's computer use tools Whats the craziest most yolo thing you've done with it? I'll start, codex has: 1. found me a website to fax medical records 2. used docusign to sign something on my behalf 3. its negotiating the sale of a watch 4. guestlist for the 5/5 party what about you?

GPT-5.5 vs Fable: ~same performance, but GPT-5.5 costs 50% less and so can do twice as much work.

wow sick new billboards from openai

🇺🇸 @StuHolden saw this @USMNT beauty developing way down the field

I have a new kind of big button that I can press for Codex. Over the next 100 days, we will select one person per day who does impressive or incredibly useful work with Codex and give them 10X usage limits for a month to see what they can do with it. First one tomorrow.

Is it just me or does Siri dictation need a vocabulary refresh? Codex autocorrects to Kodak every time. Siri…keep up.

@cansar Giddyup!

A personal update: I’m joining OpenAI to work on Codex, the best agent app in the industry. After years building consumer products, my obsession since September has been to make Block one of the most AI-native engineering orgs in the world. I’m proud of what we’ve built: faster Eng velocity with RPI in October, an internal multi-harness ADE in January, Slack-based cloud agents in February, and AI woven into every step of product development. The team is just getting started. Along the way I tried almost every agent orchestrator out there — 30+ over the past year. Codex felt special from the day it launched. Lately, it’s started to point at something much bigger. What used to be scattered across prompts, tabs, tools, files, and handoffs is starting to come together in one place. The app is becoming the single surface for knowledge work — letting you accomplish more than you ever thought possible, while staying calm and focused. You can already see the early signs: making a slideshow and editing it right there, working inside a custom site built just for you and your team, handing off to the browser and the computer while you watch it go. Getting this right takes powerful models. But it also takes taste, product thinking, and real care for the person on the other end. You see that in the product, and you feel it the moment you talk to the team. I couldn’t be more excited to join the Codex team. Together we’re going to build the future of computing and knowledge work, and we’re going to build it for you.

codex quietly becoming the only app you need to open

@Dimillian We need /goal on mobile

Did you know that on Codex Mobile you can access all your host plugins, but on top of that, you can easily send camera and library photos and files from your phone? Oh yes, plan mode is also fully available for planning on the go!

codex is insane because it's like claude code but better

Codex is a gazillion times better than Claude Code or Cowork for knowledge work. Needs a rebrand desperately.

@kappax @jxnlco “Codex, read this and codify to a skill.”

@jxnlco Bro should of just uploaded this as a skill.md would get way more traction on X no one is gonna read this end to end lmao
