get started

Two commands.
Then a wizard.

The installer asks for building blocks, shows with pictures what they become, and generates the deployment for Docker Compose or Kubernetes.

bash
$ pip install fyos-installer      # Python 3.11+
$ fyos-install                    # opens the wizard in your browser
Installer step 3: choose building blocks, with a sketch and “what it becomes”.

principles

For your own sake.
Not for ours.

On your side.

Everything runs on your hardware. No account with a third party, no API key that expires, nobody reading along.

One capability, every surface.

Built once as a hub tool, it is available in the shell, the agent, chat clients and scripts – with the same interface.

The boundary below the model.

Approvals are enforced, not requested – measured by what a step does, not by which tool it uses.

Measured, not claimed.

Every speed number comes from paired measurements on the same machine. Failures are published too.

Personal things as plugins.

The distribution contains only general parts. A cleanliness check keeps private addresses, accounts and secrets out.

Open.

Apache-2.0 for the distribution, MIT for FLE. Packages on PyPI, images on GHCR, models on Hugging Face, a report with a DOI.

An 89 GB model.
One 32 GB card.

The language model behind FYOS runs locally. Below, an answer arrives at the speed FLE measured on a workstation.

What is FYOS?

FYOS is an operating system for your AI that runs entirely on your side. In the browser you open your own desktop; every app comes as a tool from the hub, which the agent uses too. The agent asks before it does anything heavy. And the language model behind it runs on a single graphics card with FastLocalExperts — this answer at the measured speed.

how we build

Written down.
Measured. Approved.

119architecture decisions
Every larger decision written down as an ADR, with status and what it supersedes.
6.130measurements for FLE
Baseline, candidate, baseline on the same machine – with raw data and script.
3agents in parallel
Claude Code and Codex develop in their own worktrees; only what CI sees green goes to main.
1human decides
Approvals, deletions and system settings stay with the human.

What looks like solo development from the outside is a small software company on the inside: several agents, one board, fixed gates.

films

Making Rhea Fast

Eight short films about how FLE was measured – and what did not work. Every number comes from the measurement database behind the report.
