Brief

Magnitude is a local-agent toolkit that runs the entire stack (including inference) on your machine to keep data private and avoid API/token costs. Released 2026-08-07 by @tomgreenwald, it installs with one command, profiles your hardware to recommend models by quality/speed/memory trade-offs, and offers terminal-first workflows plus optional skills for Excel, PowerPoint, PDFs and Chrome.

Why it matters

Magnitude (announced by @tomgreenwald on 2026-08-07) claims to be 100% private and offline, open-source, with no token costs or API keys; its inference engine runs local models inside the agent so prompts, files, and secrets stay on your computer rather than being sent to Anthropic/OpenAI.

Key details

  • Installation and workflow: single-command setup (npm i -g @magnitudedev/cli), runs in the terminal, auto-profiles hardware to recommend models with trade-offs (quality, speed, memory), provides built-in shell/file editing/script abilities, and supports add-on 'skills' for Excel, PowerPoint, PDFs, Chrome; GitHub: github.com/magnitudedev/magn….

Introducing Magnitude: your actually local agent
100% private and offline. No token costs, no API keys. Open source.

Today's agents are local. The model isn't. Every prompt, every file, every secret gets sent straight to Anthropic and OpenAI.

Magnitude is built around local models and runs the whole stack itself. The inference engine is part of the agent, so the models run inside it, right on your computer.

It lives in your terminal, and setup is one command. Magnitude profiles your hardware and shows you which models fit, with the trade-offs between quality, speed, and memory. Pick one and start working. No painful config or server to babysit.

Out of the box, it can use your shell, edit files, and run scripts. Add skills and it can work with Excel, PowerPoint, PDFs or Chrome.

Use it for everyday work:
- Analyze sensitive data
- Manage private notes
- Review code and logs
- Search and organize files
- Build docs or slides

npm i -g @magnitudedev/cli
