Most functionality within the SDK 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.
The Vellum Client SDK, found within src/vellum/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.
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 declaratively 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.
