LM Studio

LM Studio is a free desktop application that makes running local AI models approachable for non-developers. It offers a searchable catalogue of open-weight models from Hugging Face, one-click downloads, hardware-aware settings and a familiar chat window, plus a local server that mimics the OpenAI API for your own apps. Because everything runs on your GPU or CPU, conversations and files stay private and offline. It suits privacy-conscious professionals, students and developers testing models before paying for cloud inference.
