Every build of JENSEn OS is published from meetjensen.com and nowhere else. If you found it somewhere else, it isn’t ours.

Current status
JENSEn OS has not been released for public download yet. There is no installer to hand you today, and we would rather say so plainly than park a dead button on this page.
This page is where the download will live when it ships. Everything below describes what you will be installing and what your machine will need, so you can judge the fit before the build lands.
Three ways in

One system, three front doors.

The difference between the three is how much of the setup you want to make yourself. The system underneath is identical — the same agents, the same rules engine, the same record of what was done.

Quick Start
The fast path. It sets everything up for you — the agent team, the default rules, and a working model connection — and you are giving it work within a few minutes. Choose this if you want to see what the thing does before you tune anything. Nothing here is locked; every default it picks can be changed later without reinstalling.
Custom
You choose the models and the rules. Point the agents at the frontier models through your own API keys, or at models running locally on your own hardware, or at a mix — a large model for planning, a small local one for the mechanical passes. You also set the leash here: which actions run unattended, which stop and wait for you, and which are never permitted at all.
Full Control
Fully offline, shipped on a USB drive. The models, the weights, and the system all arrive physically — nothing is fetched, and the machine never needs to reach the internet to run. This is the configuration for work that cannot leave the room: regulated environments, air-gapped networks, and anyone whose data simply is not allowed to transit somebody else’s servers.
What it runs on

Your machine, not a browser tab.

JENSEn OS is desktop software for Mac, Windows, and Linux. It installs on the machine in front of you and runs there. What it needs depends entirely on which way you run it.

Running on hosted models
An ordinary modern laptop is enough. The heavy thinking happens at the model provider; your machine coordinates the agents and holds your work.
Running fully local
A discrete GPU with real video memory, and disk for the weights. The more you give it, the larger the models it can hold and the more it can run at once.
Network
Required only to reach hosted models and to check your licence. In the Full Control configuration, neither applies and the machine can stay offline permanently.

Exact minimum specifications will be published on this page alongside the first build, once they have been measured rather than estimated.

Where the build comes from.

There is exactly one source for JENSEn OS: meetjensen.com. We do not publish to download aggregators, we do not have a mirror network, and we will never ask you to fetch a build from a file-sharing host. Anything presenting itself as a JENSEn OS installer from another origin did not come from us.

That is deliberate, and it is the same principle the product is built on. A system that runs on your own machine, holds your own data, and acts under your own rules is only as trustworthy as the channel it arrived through. One origin is easier to verify than ten.
