What Little LUMI Model actually is

Two Lumis climbing File Explorer windows on a Windows 11 desktop in Little LUMI Model

Little LUMI Model is a paid Windows 11 desktop companion from Studio LUMI, launched on Steam on 3 September 2026. Lumi walks your taskbar, climbs the window you are typing in, hangs from title bars, and naps when nothing happens. Pat her head, turn on focus mode, summon extra Lumis, or subscribe to extra characters on the Steam Workshop. This unofficial wiki maps setup, controls, affection, the 1.0.1 hotfix, and 1.1.0 Broadcast mode so you can keep her cute without wrecking a work session — or send her into OBS.

Quick start

Five steps from Steam checkout to a quiet, climbing Lumi.

  1. 1

    Install from Steam on Windows 11

    Little LUMI Model is a Windows 11 x64 utility with a bundled Java runtime. Buy it on Steam, install, and launch from the library. There is no extra runtime download and no account beyond Steam. Full first-run notes live in Getting Started.

  2. 2

    Let her walk, then open Settings

    Lumi appears on the taskbar and treats windows as terrain. Open Settings from the tray icon. Tabs start as Home, Lumi, Behaviour, Sound, Screen, and About. Patch 1.1.0 adds Broadcast for OBS — leave it off until you stream. Use the controls guide before you start throwing her.

  3. 3

    Pat once, then set focus rules

    Rub the top of her head so the cursor becomes a hand. Daily head pats and days together feed affection. Before deep work, enable focus mode and auto-hide on fullscreen from the Screen tab.

  4. 4

    Add Workshop extras only after she is stable

    The Steam Workshop can add extra characters and the LUMI Voice Pack. Subscribe, fully restart Lumi, then pick the pack on the Sound tab. Do not stack chat mods until the base pet feels solid.

  5. 5

    Summon a second Lumi when you are ready

    Tray → Call Another LUMI. Two or more chat, high-five, share credits, and march. Hotfix 1.0.1 fixed a Parade dialog freeze. Details are in multiple Lumis and the updates hub.

Is this wiki official?

Ready to let Lumi move in?

Install from Steam, pat her once, then use focus mode before a long work block. If something freezes, read troubleshooting and the 1.0.1 hotfix notes.
