About this segment
Tibo's Dot pinged him that production was down five minutes before a live demo. It linked the outage to the demo itself, and the guardrails and device setup behind Dots are explained.
From “OpenAI’s Head of ChatGPT: We’re entering a new era of AI (again) | Tibo Sottiaux”, Oct 4, 2026. Watch the full episode
“The fundamental difference in the way that we've built dots is the harness does not run on the machine.”
Takeaways
- The agent connected the outage to the upcoming live demo
- Specialist dots run with extra guardrails and monitoring
- Dots keep the harness off your machine and connect to many devices

was amazing that blew my mind or someone you've heard oh there was like something cool because the live demo just failed, right? You know, in front of everyone. So it was like, okay, well, that's not cool. But actually, my thought was, you know, it's like realized I was, you know, at Dev Day, like, you know, we have ChatGPT production when done. And so it pinged me five minutes before the live demo, which was actually quite stressful because it was like, hey, production is down.

And it's like, oh, well, you know, it's like, do you want me to try and fix it? And I'm like, I don't think you're there yet. you know, a little dot, but, you know, thank you for trying. And then, you know, then, you know, I got in touch with like the engineering teams and we started to look, you know, at what was going on. And, you know, it's like fixed by now. But having this thing that just understands like, okay, there's a pretty important thing happening. It's called Dev Day. There's like this production system. There's a live demo. It's probably using this production system. So these two things are connected and this is happening in five minutes. So I should ping him because like he probably wants to know about it. I think that's quite remarkable. That is remarkable. Wow. So I just knew that this

was coming and told you, and I love that it wanted to fix it. And you're like, not quite, you're not quite there yet. I don't think you're just like, you know, please go impress me. But you know, that would have been a better story. How do you feel about just giving you access to all these things? I don't know. Like, does it have access to the production code base? And like, you know, it has access to some production systems with guardrails. You know, so we built, We talked about specialist dots, but specialist dots just operate with additional guardrails, additional monitoring, and then on their own hardware.

So we actually run some on Mac minis. The fundamental difference in the way that we've built dots is the harness does not run on the machine. And this is maybe people have not realized. It can connect to as many devices as you want. So it has its own computer. You can actually connect it to your own laptop as well. over time, you might connect it to like 10 different devices and it can control it all.

A little bit like an octopus. So you're basically talking to your dot. It's living in some VM somewhere and it can... Yeah, might be a VM, might not be a VM. It's just like it's a thing, you know, and it can connect to many devices.
