Running a local LLM directly from Xojo is now easier than ever thanks to the MBS Xojo Plugins and their integration with llama.cpp. With just a few lines of code, you can load a model, create a context, and generate text—all on-device, with optional GPU acceleration.
In this article, we’ll walk through the basics of setting up llama.cpp with Xojo and the MBS Plugin, and then examine a complete example that loads a model and asks it simple questions.
llama.cpp is a high-performance C/C++ implementation for running LLaMA-family language models locally, optimized for CPUs and GPUs (Metal, CUDA, etc.). It is lightweight, fast, and ideal for on-device inference with small to medium-sized models.
The MBS Xojo Plugins provide a direct bridge between Xojo and llama.cpp, exposing model loading, context creation, sampling, and inference capabilities through the LlamaMBS, LlamaModelMBS, LlamaContextMBS, and related classes.

Nickenich, Germany - (November 18th, 2025) -- Monkeybread Software today is pleased to announce MBS Xojo Plugins 25.5 for macOS, Linux and Windows, the latest update to their product that is easily the most powerful plugin collection currently available for Xojo. MBS Xojo Plugins have been updated and now includes over 3000 classes and 83,000 documented features, and the versatile plugins have gained more new functions:
For macOS 26 and iOS 26 you can use our FoundationModels classes to use Apple's on-device LLM within your Xojo applications. Use SystemLanguageModelsMBS class to check whether the model is available and initialize a session with LanguageModelSessionsMBS class. You may use the model for chatting, summarization, translation and more.
In your cross platform projects you can use the open source Llama library to run large language models within your Xojo application. Load a model with LlamaModelMBS class and then create a context with LlamaContextMBS class and ask it with a prompt.
Use NSSymbolEffectMBS class and subclasses to have animated symbols in the user interface. We have classes for transitions and effect options. You can add symbol effects to NSImageView controls. You can use symbol configuration for a NSButtonMBS based control.
When running JavaScript with macOS, you can create a group of contexts with JSContextGroupMBS class. Then create contexts within that group, so they can share data.
For CURL we added a NetworkChanged method to CURLSMultiMBS class to inform CURL about a network change. The new properties for transfers allow you to know how many transfers are currently running, pending, added or done. Secure Transport was removed in favor of OpenSSL and CURLN* and CURL* classes are now subclasses for CURLS* classes to help transition to the CURLS classes.
We upgraded several classes. The WiringPiMBS module, the NSImageViewMBS, X509MBS, CGImageSourceMBS and CGImageDestinationMBS classes all go many new properties and methods for additional features.
For Windows using WebView2 control you can now set what preferred color scheme to use. You can query the directory path for the current profile and set the default download folder.
We extend our DynaPDFParserMBS class to provide details on the content of a page. You can delete individual things on a PDF page like images or text pieces. The USBSerialNumberMBS method on a folderitem provides the serial number for an USB stick on macOS. Same can be done with WMI classes on Windows.
We got new UUIDv7 functions for UUIDMBS class, the ChartDirector plugin got Windows ARM 64 bit support and you can show the manage subscriptions dialog in StoreKit2. The QLPreviewControllerMBS can now show item with custom title, the CSProfileMBS class can wait for getting all the installed profiles and the WindowsWMIMBS works better with Windows security.
Finally we updated the CURL library to version 8.16.0, DynaPDF to 4.0.102.299, expat to 2.7.3, jsoncons to 1.4.3, libarchive to 3.8.2, OpenSSL to 3.5.2, Saxon to 12.9, Xcode to 26.0 and WiringPi to 3.1.6.

The November/December (23.6) issue of xDev Magazine is now available. Here's a quick preview of what's inside:
From Idea to Prototype by Tim Dietrich Tim shares a novel way to use AI in your Xojo projects. Not for coding, but for designing, planning, and prototyping.
A Raspberry Pi Save File Dialog by Eugene Dakin There are many features of Raspberry Pi that can't be obtained via built-in methods. In today's example, Eugene uses declares to create a save file dialog.
Converting Fitbit Data by Marc Zeedar Years ago Marc got an internet-connect scale from Fitbit so he could track his weight. But it would never integrate with Apple's Health app. Now, using Xojo, Marc converts ten years of data and imports it into Health.
Android's New Developer Verification by Tim Dietrich Recently Google threw a huge twist into Android development, requiring all developers register their apps for verification in a system similar to Apple's app signing. What does this mean for Xojo developers building for Android? Tim has some answers.
