Get Started

Most functionality within the SDKs here requires a Vellum account and API key. To sign up, talk to us or visit our pricing page.

Even without a Vellum account, you can use the Workflows SDK to define the control flow of your AI systems. Learn more below.

Client SDK

The Vellum Client SDK, found within src/client is a low-level client used to interact directly with the Vellum API. Learn more and get started by visiting the Vellum Client SDK README.

Workflows SDK

The Vellum Workflows SDK is a high-level framework for defining and debugging the control flow of AI systems. At it's core, it's a powerful workflow engine with syntactic sugar for intuitively defining graphs, the nodes within, and the relationships between them.

The Workflows SDK can be used with or without a Vellum account, but a Vellum account is required to use certain out-of-box nodes and features, including the ability to push and pull your Workflow definition to Vellum for editing and debugging via a UI.

To learn more and get started, visit the Vellum Workflows SDK README.

Contributing

See the CONTRIBUTING.md for information on how to contribute to the Vellum SDKs.
