Unsloth

A desktop app for running AI models on your own computer and training them on your own data.

What it does

Unsloth is a desktop app for Windows, Mac and Linux that runs open AI models on your own computer, including chat, image, audio and video models. You can chat with them, connect them to coding tools like Claude Code, search the web, and reach your models from other devices on your home network.

Its main strength is fine-tuning: teaching an existing model new skills using your own examples. Its makers say it trains models about twice as fast while using much less graphics-card memory, without losing accuracy. It can also build training data from PDFs, spreadsheets and Word files, and export finished models in common formats.

Besides the desktop app, there is a web interface and a Python library for programmers.

Who it's for

Hobbyists and developers who want to run AI privately or adapt models to their own tasks.

Can I use it without coding?

Yes. There is a downloadable desktop app. Training models needs a capable computer, ideally with a good graphics card. New to this? Start here.
