Overview

Magnitude is an open-source inference engine and desktop app for running open models locally. It tunes kernels for each model on the user's hardware when the model is downloaded, aiming to improve speed without changing model output. Users can discover and download models, then connect supported agents with one click or use the OpenAI-compatible API. It supports Apple Silicon, NVIDIA and AMD GPUs, and CPU-only systems on macOS, Linux, and Windows. Prompts and models stay on the user's machine.

Key features

  • Tunes model kernels on the user's hardware during download.
  • Provides a desktop app with model discovery and downloads.
  • Connects supported agents with one click and offers an OpenAI-compatible API.
  • Runs on Apple Silicon, NVIDIA and AMD GPUs, or CPU-only systems across macOS, Linux, and Windows.
  • Keeps prompts and models on the user's machine.

Best for

People who want to run open models locally and connect them to an agent they already use. It also suits users who want the inference engine to tune kernels for their hardware.
