Que ce soit pour Codex ou même Cursor j’avoue qu’avoir les tâches en cours en live activities c’est une tuerie !
Ça permet de garder un œil ultra facilement sur ce qu’on est en train de faire.
Plus besoin de rouvrir l’app toutes les deux minutes. 🔥

pro tip for switching accounts even quicker on mobile
go build something cool with those +2 banked resets coming your way over the weekend 🙌
Day 26/ You can now easily switch between multiple accounts on mobile, and coming soon to desktop too. Next two days will be resets… banked… do with this what you may 👀.

next week I'm talking to @danshipper (the shippinator) at @every thesis. it'll be on television. what should we talk about?
Sailmode for iPhone Duo, a first look at my new app.
Control your Mac from anywhere, effortlessly.
End-to-end encryption, ultra-low latency, 120 fps, multi-touch, instant screen zoom, mechanical keyboard with real key sounds, night mode, 10-bit colour, Mac audio and video, on-device dictation, and yes, the Touch Bar is back.
I've been using it for the past two days and I'm blown away. Every tap, every key, every scroll is tuned to feel delightful.
TestFlight is going out this week.

Shoutout to the #parisdevdayhack builders who made it to DevDay Exchange!! 🌟
& to EVERYONE who participated:
I BELIEVE IN YOU
I only came to Paris 6 months ago.
In that time, people at my events went from their very first projects to
- building their own robots 🤖
- landing top tech jobs 👩💻
- Getting investments in their startups 📈 (some more than half a milli 🤑)
to be honest, for some of them, I really didn’t expect it! 😅
Seeing all of you grow makes me believe in people earlier.
Even to those who just did their first hackathon, no matter where you are on your journey right now:
dream bigger,
keep pushing,
keep building on the weekends
take good care of yourself.
And for the seasoned builder:
Be generous
Teach the kids
Uplift each other
Like @paw_lean and @wulfie_bain_ do!! 🫶
Together we will change the world 🫶
(Ps. I know some of y’all missed the picture moment send your best DevDay Paris selfies below 🌟🔥🚀
@daniellkumlin wya!? )
(P.p.s: London DevDay hack by @Andy_AJT up next see you there!! 🇬🇧💷)
Playing @Dimillian ‘s game on his IPhone duo
I was failing so hard he had to show me how it’s done😅
Thomas Ricouard retweeted
I have been hardcore prompting AI for 3 years now, on game dev topics mostly.
The biggest leverage is knowing the vocabulary, the concepts and the game design fundamentals.
It does a massive difference in output
I think I will create a website where I share all of that.
Might you be interested?
Just a year ago, nobody would have believed you if you told them these projects were cooked up in a weekend.

i asked GPT-6.1 Terra to show me its computer use alongside Sol.
here’s my prompt:
“I need you to find a long but generic form on the internet and record my screen while GPT-6.1 Terra fills it out in Fast mode. Then have GPT-6.1 Sol fill out the same form in Fast mode and show both recordings side by side."
in the original run of the same form:
Terra took 53.5 seconds vs 3:21.7 for Sol.
that’s a 2:28.2 difference!
that run used accessibility controls, which computer use normally defaults to)
the recorded video uses mouse controls so you can see the cursor.
GPT-6.1 Terra means business.
Our new fast, efficient model pairs sharper visual reasoning and precise computer use with clearer, more natural writing.
From decoding technical drawings to drafting proposals, filling forms to editing videos—it’s built for the whole workday.
GPT-6.1 Terra is rolling out today to Plus, Pro, Enterprise, and Edu users in ChatGPT Work and Codex.
🤖 Made with AI
Thomas Ricouard retweeted
GPT-6.1 Terra is here!! 🚀
build faster, more affordable agents that can reason over images and use computers.
+15 points vs 5.6 Terra on Agents’ Last Exam at roughly 1/3 the cost.
API pricing: $1/M input, $0.05/M cached, $5/M output.
Rolling out across paid plans in ChatGPT & Codex ✨

Guten Tag, Berlin! 🇩🇪
Kicking off our DevDay Exchange series in Europe today! Can’t wait to meet the developer community here and see what you’re building. See you soon!

QoL update for Codex devs:
You can now switch reasoning levels mid-conversation without losing your cache! Use lower reasoning for the quick stuff and dial it up when you need it, without having to rebuild the context.
and some nice CLI updates:
- Reusable prompt presets
- Change models and permissions inline
- Fixes for resuming long sessions
- Enterprise MCP sign-in and Windows proxy auth
Also dot calls connect much faster now too ;)
Thomas Ricouard retweeted
This video was edited entirely in the cloud using @HyperFrames_ and coordinated by my dot using an automatic feedback loop in our internal review app Cutroom.
Romain would review an edit, mark it as "feedback ready", my dot picks that up and then kicks off a new revision!
