LM Studio
Desktop app for running open-weight models locally — a graphical model browser, chat UI and OpenAI-compatible server in one, covering Qwen3, Llama 4, gpt-oss and Phi-4.
About LM Studio
LM Studio is the graphical counterpart to Ollama: a desktop application that lets you browse, download and run open-weight models without touching a terminal. It bundles a model catalogue, a chat interface, quantisation selection with VRAM guidance, and a local OpenAI-compatible server that other tools can call. In 2026 the models worth running through it are Qwen3 across its 1.7B to 235B range, Llama 4 Scout 17B for general use, Qwen3.6 27B for coding, gpt-oss 20B on 16GB machines and Phi-4 14B at 8GB. Everything runs offline on your own hardware.
