What each one is

llama.cpp

Inference library (C/C++) · MIT

llama.cpp is the high-performance C/C++ inference engine that underpins most local LLM tools, supporting GGUF models with aggressive quantization across CPUs and GPUs.

Runs almost anywhere, from laptops to Raspberry Pi
State-of-the-art quantization (GGUF) for tiny footprints
The engine many other tools are built on top of

MLC LLM

Universal LLM deployment · Apache-2.0

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
