About LM Studio

Who It's For

LM Studio is for anyone who wants to run AI models on their own computer, privately and for free. It's ideal for users who care about data privacy, developers needing a local AI environment, or anyone wanting to experiment with various large language models without using cloud services.

What You Get

You get a free desktop app that lets you download, manage, and chat with popular AI models like Llama and Mistral. All your data stays on your machine for complete privacy. It also uses your computer's GPU for faster speed and offers tools for developers to integrate AI into their own programs.

How It Works

Simply download and install LM Studio for your operating system. Inside the app, use the Discover tab to find and download your chosen AI model. Then, go to the Chat tab, load the model, and begin typing your questions or commands. Developers can also set up a local server to access models programmatically.

Frequently asked questions

LM Studio is an intuitive desktop application that allows you to download, manage, and run large language models (LLMs) locally on your computer. It serves as both a user interface and LLM engine, integrating with Hugging Face's model repositories to provide easy access to models like Llama, Mistral, Gemma, DeepSeek, and many others. Unlike cloud-based AI services, LM Studio operates entirely on your machine, giving you complete privacy and control over your data.

Download the latest version from lmstudio.ai for your operating system (Mac, Windows, or Linux). Follow the simple installation instructions provided on the website. Once installed, launch the application to begin.

LM Studio requires sufficient computational power to run AI models locally. At minimum, you should have 16GB of RAM for optimal performance. If you have an NVIDIA GPU, you can enable GPU acceleration to significantly speed up model execution.

Navigate to the Discover tab within LM Studio and search for models by name (such as "Llama," "Mistral," or "DeepSeek"). Select your desired model and click the download button—LM Studio will automatically download and configure it for local use.

After downloading a model, click on the Chat tab and select the Load AI Model button at the top center of the screen. Choose your downloaded model from the list and wait for it to load (typically less than a minute). Once loaded, you can immediately start interacting with the model by typing prompts, asking questions, or assigning tasks.

Yes, you can switch between models at any time. LM Studio stores all your downloaded models in the My Models tab, allowing you to experiment with different models and compare their capabilities.

If you have an NVIDIA GPU, enable GPU offload in the Chat tab to accelerate processing. You can slide the GPU Offload setting to maximize the number of layers your VRAM can handle (for example, 14 layers for an NVIDIA RTX 3090).

Yes. LM Studio includes a Developer tab where you can run a local inference server. This enables you to access LM Studio through its own APIs and SDKs using TypeScript, Python, REST endpoints, and OpenAI-compatible endpoints.

All models in LM Studio support at least some degree of tool use. Models with native tool use support are marked with a hammer badge in the application and generally perform better in tool use scenarios.

LM Studio supports various model formats including .gguf and .safetensors files downloaded from Hugging Face.

Yes, LM Studio supports Model Context Protocol (MCP) connections, allowing you to connect MCP servers and expand functionality. This enables integration with various tools and services for enhanced capabilities.

Absolutely. Since LM Studio runs entirely on your local machine, all your data and interactions remain private—you're not sending anything to cloud servers. This makes it ideal for working with sensitive information.
