Magnitude Magnitude
Magnitude is an open-source inference engine and desktop app for running open models on the hardware you already own. It profiles your machine, estimates tokens-per-second for every model and quantisation in its catalog before you download anything, ranks candidates by speed, accuracy, intelligence and memory, and then tunes the chosen model end to end — context size, placement, batching and speculative decoding — for your exact hardware. A Rust engine built on llama.cpp keeps full context windows for parallel agents and stays responsive while other work runs. One click connects the local model to coding agents such as Pi, OpenCode, Hermes, OpenClaw, Codex, Claude Code, Oh My Pi and Cline; models load on demand and unload when idle.
Magnitude (a Y Combinator company) published @magnitudedev/cli 0.1.5 on 23 September 2026 and reached GitHub's monthly trending list with about 5,000 stars; the project recently repositioned from a browser-agent/coding-agent focus to a hardware-aware local inference engine with one-click agent connections.
As of
- Hardware profiling with tok/s estimates for every model before download
- Model recommendations ranked by speed, accuracy, intelligence and memory
- End-to-end tuning including speculative decoding, placement and batching
- One-click connection to Pi, OpenCode, Hermes, OpenClaw, Codex, Claude Code, Oh My Pi and Cline
- Runs on Apple Silicon, NVIDIA, AMD and CPU-only machines, including DGX Spark and Strix Halo
- On-demand model loading and unloading when idle or memory is tight
- Fully private and offline after download; bundled magnitude CLI
Developers who want to run coding agents against local open models but do not want to guess which model and quant their laptop or workstation can actually handle.
Teams that need frontier-model quality for every task, or users on machines too small for useful coding models regardless of tuning.
Magnitude is free and open source under the Apache-2.0 license, with desktop downloads for macOS, Windows and Linux that bundle the magnitude CLI. Models run locally, so there are no token costs, API keys or rate limits.
Magnitude fills a real gap next to Ollama and LM Studio by helping you choose and tune a model rather than just run one; it is young and evolving quickly, but the hardware-aware recommendations make local agent workflows far less trial-and-error.
