Extensions Overview

The current Jan Desktop Client has some default extensions built on this framework to enhance the user experience. There are two types of extensions:

Model Providers: These are extensions that enable Jan to support cloud-based models and provide the engine to support additional local models.
Core Extensions: These are built-in tools for managing and monitoring the Jan's system.

Specific Extension Settings

Jan offers an Extensions settings menu for configuring extensions that have registered their settings within the application. Here, you can directly integrate Remote Inference Engines with Jan without inserting the URL and API Key directly in the JSON file. Additionally, you can turn the Logging extensions available on or off in Jan. To access the Extension settings, follow the steps below:

Navigate to the main dashboard.
Click the gear icon (⚙️) on the bottom left of your screen.

Settings

Click Extensions.
