Huuuge kudos to @hollllyli for how she handled the whole situation! Also this being a one-take shot is brilliant. As for the cute dots animations…
dots demo. Now... with better WiFi.

I am still amazed at what just happened.... I now have Codeck fully integrated inside Codex. Together with living prompts on the slides, advanced formatting, open/save from disk, drafts caching, full-screen playback and much more! 🤯 This is insane, huge kudos to the team behind this! 👏 It unlocks whole new world of possibilities we are only beginning to understand. So excited for the future of plugins! cc: @mxstbr @romainhuet @embirico
Today's goal: create plugin extension for Codeck so you can create and preview decks live directly inside Codex! ✨ cc: @mxstbr github.com/lkuczborski/Codec…

Worked with 6.1 Sol all day today and it has been really great so far. Super efficient, great output and requires less steering. It's in an entirely different league compared to 6 Sol. You can really feel Astra quality in there. I think 6.1 Sol High will be my new daily now. Great job on this one!

I built Apple Reminders…inside ChatGPT. This is real, and it's a native ChatGPT Extension you can try right now. Free and open source. Version 2.0 of my Reminders CLI, RemCTL, is out now with complete support for MCP and the brand new @OpenAIDevs MCP Extensions. With RemCTL 2.0, you have a power-user interface for Reminders inside ChatGPT for Mac. You can use keyboard shortcuts, there's a ⌘K palette, and view tasks as lists, Kanban, or Calendar. It's basically "Reminders Pro". But most importantly, you can work with ChatGPT in this Reminders UI and ask it to do whatever you want. Attach any task to a conversation, or select multiple ones and pass them to ChatGPT. I was inspired by @danshipper's concept of "Codex apps", and when I saw @mxstbr's announcement yesterday, I knew what to do. This feels like a brand new way of getting work done, and I'm excited to build more. Have fun! github.com/viticci/remctl

Fun note from Tibo at the closing q&a of DevDay: dots get their own Linux cloud computer, and that cloud computer comes preloaded with apps like Blender! I checked with my dot to get a fuller list of the preloaded apps and tools

I also have a little announcement for DevDay. I asked Tibo to include it in the presentation but he didn't read my slack DM 😭 My first onboarding project is merged. I fixed this issue once and forever! I reduced amount of disk writes by 50% and the size of stored files by 4x
1/ Codex is quietly killing your SSD. It writes diagnostic logs to disk non-stop, even when you're not doing anything. Your SSD has a write limit. Codex is burning through it in the background. One command fixes it 👇

••• in EU 🔜
Is there a way for me to community note myself to add that that excludes the EU/UK/CH? Sorry folks, I should remember as I grew up in CH. Working to get to you soon!

GPT-6.1 Sol is here. Upgraded with stronger agentic coding and computer use, near-Astra performance, and cached input at a 95% discount to standard input pricing. GPT-6.1 Sol is built for complex refactors, deep codebase investigations, and long-running agents across apps.

Can't wait for DevDay announcements. This will be a culmination of many months of work for all the awesome folks at @OpenAI. Even before we see what they have in store for us I wanted to give a huge token (pun intended) of appreciation for all the work they put into making Codex the best place for agentic development and all that at insane pace. Kudos to the entire team! 👏 @romainhuet @ajambrosino @thsottiaux
That was yesterday, today is DevDay. And it's all good news. I'm surprised we've kept it all under wraps.
