Magnitude is an open source inference server that runs local language models optimized for your hardware and integrates with code agents you already use.
The tool solves the problem of running capable language models locally without cloud API costs or privacy concerns. It works by profiling your machine's hardware capabilities, recommending models that fit those constraints, then downloading and tuning them for optimal performance on your specific setup. The server handles model loading on demand, unloading when idle or when memory fills, and applies optimizations like speculative decoding and concurrency tuning automatically.
Magnitude suits developers who want to run agents locally with full privacy and no token costs, particularly those with resource-constrained hardware like Raspberry Pi or machines with limited memory and bandwidth. The tool is designed to work with popular code agents including Pi, OpenCode, Hermes, OpenClaw, Codex, Claude Code, Oh My Pi, and Cline, or you can use its built-in harness. It supports macOS and Linux natively, with Windows support through WSL. The README emphasizes that setup is agent-first: you send a prompt to your agent and it walks through model selection and configuration automatically, rather than requiring manual setup.
The project maintains active engagement with its community through documented channels and shows ongoing development focused on the core inference server and hardware profiling capabilities.
