I Built an AI Operating System With GPT-6 Astra

Today, we're going to be running through how to use GPT-6 to build a powerful, agentic operating system. So, one of the things that I found with GPT-6 Astra is that it's incredibly powerful for building and designing your own tools, including the agent operating system. Now, if you're wondering, okay, what is an agent operating system? Basically, it's where all your agents can stay in one place. You can build custom workflows to build and automate anything. And it's incredibly easy to use and set up with something like GPT-6 Astra. The other thing that I would say here, and this is absolutely massive, is that it's so much faster for building with. And what I mean by that, for example, is like if you're using Claude right now, Claude Fable 5 or 5.1, it's so slow, it often makes mistakes, it misses obvious things, and it just seems so bloated and slow to use that it struggles. Now, if you had asked me a few weeks ago, okay, why would you use Codex instead of Claude? I couldn't tell you, but now I can. And what it is is the new model from GPT-6 Astra. So this is really, really powerful stuff. Let me show you an example here. So I have a coding project that I've built directly inside Claude. I've been doing that for months, right? And that is the agentic operating system that you can see right here. Now, the biggest thing that's hit me is that when we're using this, I thought, you know, I don't want to move and transition everything from the Claude setup that I have on all my coding projects over something like Codex. That would be a nightmare. It would take a long time. It would be slow. It would be time consuming. I wouldn't even know where to start. But one thing that I actually found is like, you can just take it, if you're running a project locally of, you're coding something out locally, like for example, this system that we've got here, you can literally just take a screenshot and you can copy that, right? So you can copy this, and then we can go over to Chat GPT, which is what I did over here. So I took a screenshot and plugged that in. And I said, can you improve the memory galaxy so it looks more beautiful, more interesting, more captivating, and more attention grabbing, and is even more useful. See the screenshot attached. This is running locally inside our Agenta OS. So you see how I don't have to give it any instructions. I don't even have to load in the files locally. I don't have to tell it which directory or which local folder this is running from.

Astra just gets it, right? And this is on Astra medium. This isn't even like the highest setting for Astra. So it's really, really powerful for building Agenta cooperating systems. Now, if you're wondering where to start, here's what I recommend to you, is that you look at where are you spending your time right now. So for me, for example, when I was building this out with Astra yesterday, there were three things I wanted to improve. Number one was the actual UI of the whole project, which didn't look very nice before. And so what I actually did is I took a screenshot of the system here, and I just went over to Chat GPT, and I said, listen, I want to upgrade the UI. Can you improve the UI so that it looks more beautiful?

And you can see what the old version looks like. So this was the old version, and this is the new version. Quite a big difference. Like it's subtle, but it definitely looks a lot nicer. And so we literally said, can you update the HNOS running locally? Add this address to the codec section is using GPT-6 Astra as well.

And it just, you know, we said, can you improve the UI and upgraded the UI? Add a GPT-6 Astra inside the codec section and also added it inside Hermes. Now, at this point, you might be saying, OK, well, why would you use GPT-6 or GPT-6 Astra directly with something like an agentic operating system? The reason I'd recommend it, three things. Number one, you can just have it as a drop down inside Hermes. So we can instantly, well, I can instantly just click and switch between my Hermes profiles and have a new one set up Astra.

Then we also have, for example, a new one set up with Codex. So I can switch between models here. I actually have Codex with OmniRoot and HY3, which are two free models we can plug in. And we've also got Astra ready to go right there. So we can switch between them. Super easy and simple. And then finally, for example, we can build custom tools. Like I can have a whole section just for SEO, for keyword research and for generating content.
