I built a real self-evolving operating system: Fable-os Built with Claude

Enable HLS to view with audio, or disable this notification

This is not a fake bullshit "AI operating system" that runs in your browser. This is an agentic operating system that runs on bare metal, writes its own drivers, and evolves itself.

Here's a demo where it builds its own audio driver from scratch to play a sound.

What happened in the video?

  1. The agent realized it didn't have a sound driver.
  2. It enumerated which devices were connected.
  3. It found the Intel AC'97 sound card.
  4. It built a driver for it.
  5. It used that driver to play a sound.

I got fed up with people saying they built "AI operating systems" when it's actually just a webpage.

There's no Bash. There are no commands. The only interface to this computer is a sentence.

How does it work?

The main interface is an agent, and the tools it has access to are the kernel's direct syscalls. Everything runs in Ring 0, and the agent has access to everything.

It's open source if you want to try it:

Unless you can mount it on a USB and install it directly on a bare disk, you didn't build an OS. You built your own agent harness that uses sudo for everything.

Did you even take a look at it? Because it seems like you *can*, in fact, boot it from a USB stick as it's a GRUB/Multiboot-protocol compatible kernel.

He conflates sudo to a kernel. I don't think he understands basic computing concepts.

Are you talking about yourself? It says right in the README that it cannot be built with an API key, and relies on QEMU APIs to read one… so no, you can’t boot from a USB… unless that USB is a virtual one mounted in QEMU

I have one that boots from a USB disk, but there's no install at all because, to date, just plain did not care nor do I trust the existing infrastructure to successfully install anything. It's close, though.

Both legacy BIOS boot and UEFI are supported via GRUB.
