LM Studio Review: Discover, Download and Run Local LLMs on Your Own PC
LM Studio is a free desktop app that lets you discover, download, and run large language models locally on Windows, macOS, and Linux. Models run fully offline with llama.cpp on CPU/GPU (and Apple’s MLX engine on Apple Silicon), with no coding required and no data leaving your machine.
What is LM Studio used for?
- Running open-source models (Llama, Mistral, etc.) locally for private chat.
- Testing and comparing models from Hugging Face (GGUF/MLX).
- Providing a local OpenAI-compatible REST API server for your apps.
- Headless deployments with the “llmster” daemon on servers.
Key Features
- Built-in model browser and in-app chat interface.
- Local OpenAI-compatible API server (chat/completions and more).
- llama.cpp and MLX engines for CPU/GPU inference on all platforms.
- Free for personal and commercial/work use (no license fee).
Pros & Cons
Pros: free, fully offline and private, easy model management, local API server for integration. Cons: performance depends heavily on your hardware (RAM/VRAM), the core app is not open-source, larger models need a capable GPU.
Pricing
LM Studio is free to download and use, including at work. Optional cloud inference (Bionic) has paid tiers such as Bionic+ ($20/month) and Pro ($100/month).
Verdict
If you want private, free AI chat on your own hardware, LM Studio is the easiest way to get started running local models.
