What each one is
MLC LLM
MLC LLM compiles and runs LLMs natively across GPUs, browsers and mobile devices using machine-learning compilation for hardware-accelerated local inference.
- Runs on iOS, Android, browsers and GPUs
- Hardware-accelerated via compilation
- True universal deployment
Cortex
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
MLC LLM is universal LLM deployment, while Cortex is local runtime (CLI). MLC LLM leans more advanced-friendly, whereas Cortex is more suited to beginner users. In short, MLC LLM fits running models on phones and the web, and Cortex fits a clean Ollama alternative with swappable engines.
Which should you choose?
Choose MLC LLM for running models on phones and the web. Choose Cortex for a clean Ollama alternative with swappable engines.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
