 Jan includes a built-in API server that is compatible with OpenAI's API specification, allowing you to interact with AI models through a local HTTP interface. This means you can use Jan as a drop-in replacement for OpenAI's API, but running entirely on your computer.
 
+Jan uses **Cortex** as its core engine for running AI models. If you need a standalone API server without Jan's desktop interface (for example, in server environments or for command-line usage), you can use Cortex directly: https://cortex.so.
