Summary

Magnitude is an open-source inference server that runs AI models locally on your hardware, integrating with coding agents to ensure privacy and no data leakage, with setup in one command.

run agent harnesses 100% private & offline. (no token costs, no API keys, 100% open-source) your agent runs locally. the model doesn't. every prompt, every file, and every secret still leaves your machine before the agent does anything with it. Magnitude fixes that. it's an open source inference server that runs models on your own hardware and plugs into the coding agent you already use. setup is one command. it profiles your machine, measures the memory bandwidth that sets your token rate, and hands back complete configurations instead of a list of models. each one names a model, a compression level, a context size, and a speed range you can expect. pick one and start working. it doesn't replace your harness. setup asks which one you want and writes that config for you. Pi, OpenCode, Claude Code, Codex, and Cline all work, and there's a built-in one tuned for local models if you don't have a harness yet. that one uses your shell, edits files, and runs scripts out of the box. add skills and it handles Excel, PowerPoint, PDFs, or Chrome. everyday work it covers: → analyze sensitive data → manage private notes → review code and logs → search and organize files → build docs or slides Apache 2.0. no rate limits, and nothing leaves the machine. 𝗻𝗽𝗺 𝗶 -𝗴 @𝗺𝗮𝗴𝗻𝗶𝘁𝘂𝗱𝗲𝗱𝗲𝘃/𝗰𝗹𝗶 the repo is here: http://github.com/magnitudedev/magnitude… (don't forget to star ) i wrote the full breakdown of why picking the configuration is the hard part. the article is quoted below.

run agent harnesses 100% private & offline.

(no token costs, no API keys, 100% open-source)

your agent runs locally. the model doesn’t. every prompt, every file, and every secret still leaves your machine before the agent does anything with it.

Magnitude fixes that. it’s an open source inference server that runs models on your own hardware and plugs into the coding agent you already use.

setup is one command. it profiles your machine, measures the memory bandwidth that sets your token rate, and hands back complete configurations instead of a list of models. each one names a model, a compression level, a context size, and a speed range you can expect. pick one and start working.

it doesn’t replace your harness. setup asks which one you want and writes that config for you. Pi, OpenCode, Claude Code, Codex, and Cline all work, and there’s a built-in one tuned for local models if you don’t have a harness yet.

that one uses your shell, edits files, and runs scripts out of the box. add skills and it handles Excel, PowerPoint, PDFs, or Chrome.

everyday work it covers:

→ analyze sensitive data → manage private notes → review code and logs → search and organize files → build docs or slides

Apache 2.0. no rate limits, and nothing leaves the machine.

Easy local inference for agents

Documentation Discord Follow Magnitude on Twitter GitHub Repo stars npm version

An open source inference server that profiles your hardware, recommends the best local models for it, then downloads, tunes, and runs them. Use the built-in harness or connect OpenCode, Pi, Hermes, or whatever you already use.

Magnitude works with Pi, OpenCode, Hermes, OpenClaw, Codex, Claude Code, Oh My Pi, and Cline, and leading local models

Get started

npm i -g @magnitudedev/cli && magnitude setup

Magnitude profiles your machine and shows you the best local models for it. Choose one and Magnitude downloads it, then connects it to your harness of choice.

Magnitude supports macOS and Linux. Windows is supported through WSL.

Why Magnitude?

  • Set up in one command: pick a recommended model and it launches your harness
  • Knows your hardware: profiles your chip, memory, and bandwidth
  • Recommends what fits: the best models for your machine, with estimated tok/s
  • Tuned end to end: speculative decoding, concurrency, all set for your machine
  • Models on demand: loaded on request, unloaded when idle or memory fills
  • Fully private and offline: models, prompts, and files stay on your machine
  • Free to run: no token costs, API keys, or rate limits
  • Open source: Apache 2.0, yours to modify

FAQ

What is Magnitude?

An open source inference server your agent sets up and operates through the Magnitude CLI. It profiles your hardware, recommends the best models for it, and runs them tuned to your machine.

What hardware do I need?

There’s no fixed minimum. Magnitude profiles your hardware and recommends the best models for your machine. More memory lets you run larger models.

Why not just have my agent set up Ollama?

Your agent can install Ollama and pull a model, but it’s guessing. It doesn’t know your hardware, which quant fits, or how fast it’ll run. Magnitude gives it a curated catalog with recommendations computed for your machine. Setup is agent-first, through a headless CLI that connects the model to your harness. Inference is built for agents. Models load just in time, unload when idle or memory gets tight, and concurrency is handled for you.

Which harnesses work with it?

Pi, OpenCode, Hermes, OpenClaw, Codex, Claude Code, Oh My Pi, and Cline. During setup, your agent connects your harness to the model you pick. Or use Magnitude’s built-in harness.

Do I need to manage Magnitude after setup?

No. It runs in the background, loads models when your agent needs them, and unloads them when idle or memory gets tight. Your agent can install or switch models through the Magnitude CLI anytime.

Does my data go to the cloud?

No. Prompts, files, and models stay on your machine.

Can it run completely offline?

Yes. Once Magnitude and a model are downloaded, no internet connection needed.

Can I use models outside the catalog?

Yes. You can download compatible GGUF models from Hugging Face and use them in Magnitude.
