Welcome to Mach Studio
One desktop app for the AI subscriptions you already pay for, plus local models that run on your computer.
Mach Studio is a desktop app for working with AI agents. Bring the subscriptions you already have, run open models on your own hardware, and switch between them without leaving the app.
One app for everything you already pay for
If you have Claude Code or Codex CLI, sign in to those accounts inside Mach Studio and use them as the agent behind your sessions. Prefer open source? OpenCode runs inside Mach Studio too. Pick a harness and model for each chat, keep more than one account signed in, and move between them freely. Every session gets a project folder, tabs for files, a browser and a terminal, and a transcript you can search later.
Local models whenever you want them
Browse a catalog of open models, download one, and chat with it on your computer. Your data stays with you, and it works with no account at all. Local models, your own API keys, and your subscriptions are always free.
Cloud models when you need more
Sign in with your Syzygy account to add cloud models from the Syzygy catalog. Pay as you go, or go Pro for $20 a month with $20 of monthly inference credits included. Pro also unlocks hosted integrations, automations, remote control, and cloud environments.
