DOCUMENTATION
Build with System One.
Documentation for System One — publishing decision models, the systemone.yaml specification, the SDK and CLI, the HTTP API, and fine-tuning with Laya Studio.
Why a different home
System One models decide instead of write. Why they need a registry of their own rather than a corner of a hub built for language models.
ReadGetting started
Create an account, publish a decision model, and understand what the registry stores.
Readsystemone.yaml
The manifest specification — the decision-native metadata that makes models on the registry comparable.
ReadSDK and CLI
The systemone Python package: browser login, search, pull with a shared cache, create and push.
ReadCLI reference
Every systemone command and option, the environment variables it reads, exit codes, and recipes for scripts, CI and AI coding agents.
ReadHTTP API
The registry API: authentication, search, downloads, publishing, device login, organizations and builds.
ReadFine-tuning with Laya Studio
Train a decision model locally with Laya Studio and publish the result, with lineage recorded automatically.
ReadLaya Studio
The open-source fine-tuning environment for Laya decision models. Train locally, evaluate calibration, and publish the result here.
