I did this. Fuck what anyone else says, just put the pedal to the metal and BUILD. Push spaghetti code. Nobody cares about OOPs. Doesn’t matter what anyone thinks. Just keep on doing. Document in public. Don’t listen to the haters. Release more than you refactor. Just keep pushing. Nobody cares, nobody notices, that’s the key, just fucking PUSH. That’s the way out, that’s what works, 100% times.

mildly interesting: slept for > 10 hours for the first time in a year infact slept so hard that my watch alerted me as if it was an outlier and stopped recording sleep after awhile

holy shitt!

appshots in codex is the most useful piece of software on my Mac most of my prompts these days are: - cmd cmd investigate this - cmd cmd open a PR to fix this - cmd cmd run the eval on these set of prompts and discussion - cmd cmd set a heartbeat to keep following up with this and many more cases trust me, you’ve got to try it

Been tinkering on this docs agent for a while and excited to share it more broadly 🎉 This would have been impossible to pull off in such a short time without Codex. I'll share a more detailed breakdown of the build process soon for those curious!

I’m biased but two of my favourite companies collaborating together to takeover London today 😁 @vercel @OpenAIDevs

Thursday Codex updates: - Developer Mode for Browser use with controlled CDP access - deeper debugging for network, console, runtime errors, perf, and page state - /init in the app composer - customizable macOS Dock icons - Computer Use for more Enterprise users - Windows per-app access controls - Unread chats in the command menu - Browser use up to 2x faster - rate-limit reset banking for Plus and Pro referral invites to earn more resets during the promotion - clearer summaries, plugin management, usage-limit guidance, and lots of fixes across Browser, automations, SSH, Mobile QR pairing, PRs, MFA, and more

PSA: Everyone across Go, Plus, Pro & Business gets a usage limit reset to use whenever they want! And for the next 2 weeks if you invite a friend to use codex both of you get a reset too :) Codex for everyone (including resets) Enjoy!

Update: Shoutout to @reach_vb I'm in! Order has been restored.

Today we’re announcing Macrodata Labs. Over the last few years, @HKydlicek and I have been turning a large part of the internet into some of the largest open LLM pre-training datasets. Through FineWeb, FineWeb2, FinePDFs, FineTranslations, and related work, we got a front-row seat to how scaling compute and data drove progress in LLMs. We are starting to see a similar takeoff in robotics. Building on advances in LLMs and VLMs, robotics is finally starting to scale. But physical data is messy in ways text isn’t: large video files, multi-rate sensors, many different formats, and open questions around what signals to record, which annotations matter, and how to turn all that context into better policies. That makes data work in robotics especially important. Teams need to extract as much signal as possible from every demonstration, trajectory, video frame, and sensor stream, without rebuilding their whole data stack every time they change robot, sensors, format, or labeling method. We think the right tooling for this is still missing. That is what we created Macrodata Labs to build. Our first step is Refiner, an open-source framework for processing robotics datasets. We designed Refiner to handle a variety of robotics formats and help teams extract more signal from each demonstration. It is shipping today with support for hand-tracking, subtask annotation, and reward model scoring. We are also launching a cloud version of Refiner, so teams can focus on their data instead of infrastructure. With a one-line code change, the same pipeline can scale on our platform, with sharding, checkpointing, model deployments, failure recovery, and detailed observability built in. We’re fortunate to be backed by Air Street Capital, Drysdale Ventures, OPRTRS club, Kima Ventures, YG (Alex Yazdi), >commit, Thomas Wolf, and many incredible angels from top AI labs and technology companies. I’m excited to keep exploring how better data work can push the frontier of AI, now in the physical world. If @macrodata_labs sounds interesting to you, or if you are building in the space, I would love to hear from you.

what’s the wildest thing you built with codex so far?

Just another Tuesday

Codex Mobile updates: - choose a branch, create a worktree, and run setup scripts for new threads - new Codex profile with usage stats and token activity charts - create and manage /goal from mobile add inline review comments to changed files - start side chats from selected transcript text - edit your latest prompt - skills and plugins now appear inline in the composer - better Windows attachments, queued prompts, navigation, Face ID, archived threads, and overall UI polish

Won the Codex event’s mini hack run by @Andy_AJT! Built a fun little chrome extension meant to give younger audiences a fun way to interact with AI. @reach_vb was a big fan too :) - Has context of the page that you can chat with - Pomodoro timer and clock - Blacklist websites to avoid distractions - Follows you across websites and makes sure you’re doing your work Took less than an hour to spin up using Codex, and will put the new credits to good use! Open sourced it so do make some changes or develop it further, link below (BYOK), plus will put it on the Chrome Store as well. I encourage everyone to find an hour and make cool stuff

The Codex Community meet-up vibes are immaculate, led by 🇬🇧 ambassador GOAT @Andy_AJT, @zqwq333 (@dawncapital), @mayvencraft (@vercel) and @reach_vb (@OpenAIDevs)!
