What each one is
LM Studio
LM Studio is a polished desktop app that lets you discover, download and chat with local models through a visual interface, with an optional OpenAI-compatible local server.
- The most polished GUI for exploring local models
- Built-in model browser with quantization details
- MCP-capable developer path and a local API server
llama.cpp
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
Key differences
LM Studio is desktop app (GUI), while llama.cpp is inference library (C/C++). Their licenses differ (Proprietary vs MIT), which matters if you ship a commercial product.
