LM StudioLM StudioSince 2023-04

LM Studio is the premier desktop application for discovering, downloading, and running large language models locally on your personal computer. With a polished visual interface, LM Studio makes running models like Llama 3.3, DeepSeek-R1, Mistral, and Qwen as simple as a single click, keeping all personal conversations, code, and documents 100% private and offline on your hardware. Whether running on Apple Silicon with unified memory or dedicated Nvidia/AMD GPUs, LM Studio automatically configures optimal hardware acceleration (Metal, CUDA, ROCm, Vulkan) for smooth, high-speed local inference.

Beyond conversational chat, LM Studio includes a built-in local developer server that exposes OpenAI-compatible `/v1/models` and `/v1/chat/completions` endpoints on localhost. This enables developers to connect IDE extensions (Cursor, VS Code, Windsurf) and local agent pipelines directly to offline models. It features comprehensive support for GGUF model formats from Hugging Face, multi-model side-by-side benchmarking, GPU layer offloading controls, and system prompt presets.
