Running AI locally means the model works directly on your computer instead of relying on a remote cloud service. Tools such as LM Studio, Ollama and llama.cpp make local inference accessible to beginners and developers. Once the model files are downloaded, some setups can operate completely offline, keeping prompts on your device.

Check Your Hardware

Check Your Hardware

Before installing anything, check your computer’s RAM, processor, GPU and storage. LM Studio recommends at least 16GB RAM on Windows and 4GB dedicated VRAM. Smaller models are more practical for modest hardware, while larger models require substantially more memory. Your available resources should determine which model you choose.

Pick Your AI Platform

LM Studio offers a graphical interface for downloading and running models. Ollama provides a simple command-line experience, while llama.cpp gives advanced users greater control over inference. LM Studio supports models such as Qwen, Mistral, Gemma and Llama across supported Windows, macOS and Linux systems.

Download a Model

After installing your preferred platform, download compatible model weights. LM Studio lets users search and download models through its Discover interface. Models can use formats including GGUF and safetensors. Choose a model size appropriate for your computer because larger models require more memory and can reduce performance.

Load and Start Chatting

Load and Start Chatting

Once downloaded, load the model into memory and start interacting with it. In LM Studio, users select a model through the model loader before opening a chat. Ollama offers a command-line alternative, with commands such as ollama run llama3 launching a local model directly.

Use AI Offline

Use AI Offline

Local AI can be useful when privacy and offline access matter. LM Studio says downloaded models can run without an internet connection, while documents used for local RAG remain on the computer. This makes local inference useful for private documents, experimentation and workflows where sending data to cloud servers is undesirable.

Connect AI to Other Apps

Connect AI to Other Apps

Local models are not limited to chat interfaces. LM Studio can provide OpenAI-compatible endpoints, while llama.cpp can launch an API server. Developers can therefore connect local models with applications, scripts and other tools. With the right hardware and model, a PC can become a private AI workstation.
