What is Banh?

Banh is an open-source CLI and TypeScript runtime. A model answers bounded questions about your input; your rules decide what happens next. You write both in one YAML file.

1. Input: JSON or text, such as a support ticket.
2. Decisions: pick an option, answer yes/no, or score a scale. All decisions run in one batch.
3. Flow: ordered rules on decision values. The first match returns your output.

Rules are deterministic for a given set of decisions. Banh doesn’t run agent loops, execute code or take actions; it returns a value for your application to act on.

Availability

• CLI and libraries: 0.1.0-alpha.1 on npm, MIT-licensed. Local runs use native Laya by default; remote runs use Jev through the TypeSafe API.
• Banh Cloud: early release with managed Jev and self-service signup while places are available.

Keep inputs short. Native Laya has a 512-token context window, including question headers; longer input may be truncated.
