About Syzygy
Summary
Syzygy builds ultra-compressed, task-specific AI models and the local inference stack to run them on Apple Silicon, targeting enterprises and developers who want to own their AI layer instead of routing queries through third-party API vendors. Its Mach 1 Additive architecture runs a 35B mixture-of-experts model at 1.7 bits per weight, retaining 96.3% of full-precision benchmark scores while fitting on a 16 GB Mac. The product bundle spans a desktop coworking app, a local inference engine, and a TypeScript agents SDK, replacing cloud inference calls with on-device, proprietary model deployments.
Business model
A free tier plus paid plans, with pricing listed on the website.
Go-to-market
Developers and enterprises adopt the stack through a self-serve Mac download and in-browser demo currently in beta, with the desktop app as the primary entry point.
