We have released a mod creation toolkit (SDK) that lets you add or modify features in Little LUMI Model to suit your needs.
You can make LUMI react to clicks, petting, and alarms, or add dialogue, menus, and shortcuts. You can also create mods containing artwork, behaviours, and translations.
If you are getting started, download the latest version of LittleLUMI-ModSDK from the download page below, extract it, and open plugin-guide.html. The guide takes you from installing the required tools to your first example, so even those new to programming can follow along. Korean and English guides and examples are included.
The currently available SDK 1.3.0a is a revision for Little LUMI Model 1.3.0. Please choose an SDK that supports the version of the main app you use. Creating mods requires JDK 25 and Python 3, and testing them requires an installed copy of Little LUMI Model.
After installing a mod that contains executable code, review the information in Settings → Mods and enable the mod. It will take effect when you restart the app.
