Free App Runs AI on Your Laptop, Twice as Fast and Private
Your AI stays home — no monthly fees, no data sent to the cloud.
Magnitude is a free, open source inference engine that runs open models on your own computer. It's a desktop app for macOS, Windows, and Linux that compiles and tunes its kernels on your actual device before a model runs, so they fit your exact chip — up to 2x faster than llama.cpp, with 92% faster decode on Metal and 19% on CUDA. Prompts, files, and models stay on your machine, and no internet is needed once a model is downloaded. There are no token costs. One click connects the agent you already use — Pi, OpenCode, Hermes, OpenClaw, Codex, Claude Code, Oh My Pi, and Cline — and anything else works through the OpenAI-compatible API. It runs on any Apple Silicon, NVIDIA, or AMD GPU, or nothing but a CPU; there is no fixed minimum.
