What each one is

LocalAI

Self-hosted API server · MIT

LocalAI is a self-hosted, OpenAI-compatible API that runs LLMs, image and audio models in containers, designed so the same client code points at local or hosted models.

  • Drop-in OpenAI API replacement for dev-to-prod parity
  • Multi-modal: text, image and audio in one server
  • Container-native, Kubernetes-friendly deployment

Cortex

Local runtime (CLI) · Apache-2.0

Cortex is a local AI engine with a simple CLI, an OpenAI-compatible API and multiple backends (llama.cpp, TensorRT-LLM), designed to power the Jan desktop app or run standalone.

  • Multiple inference engines behind one CLI
  • OpenAI-compatible server out of the box
  • Backed by the team behind the Jan desktop app

Key differences

LocalAI is self-hosted API server, while Cortex is local runtime (CLI). Their licenses differ (MIT vs Apache-2.0), which matters if you ship a commercial product. LocalAI leans more intermediate-friendly, whereas Cortex is more suited to beginner users. They also differ in how they run (Self-hosted vs Yes). In short, LocalAI fits teams shipping local inference inside a product, and Cortex fits a clean Ollama alternative with swappable engines.
