Who it's for

  • Those who want to verify firsthand what the program does. Because it is open-source, you can inspect the code.
  • Those who want to switch between local models and external services in a single interface.
  • Those required by company policy to use only open-source tools. It is easier to pass compliance reviews because you can see what data goes where.

Drawbacks

  • Your computer's hardware is the limit. Larger models will not run if you lack sufficient memory.
  • Compared to LM Studio, the process of finding and downloading models is less beginner-friendly, so you need to know the model names beforehand.
  • The interface is in English and Korean resources are scarce, making it hard to find help when you get stuck.

Getting started

  1. Download and install the program from the official website.
  2. Choose and download a model from the list that fits your computer's memory.
  3. Ask a few questions in Korean to check if the performance meets your needs.
  4. If needed, enter API keys for external services to use them alongside local models in one place.
  5. If you plan to use it for work, check the commercial license terms of the downloaded model.
