Build reliable multi-agent applications with ADK Go 2.0. Discover our new graph-based workflow engine, built-in human-in-the-loop, and dynamic orchestration

ADK for Go 2.0 introduces a graph-based workflow engine that enhances the development of production agent applications by allowing developers to compose multi-agent workflows in a structured, reliable, and observable manner. This new version incorporates features such as human-in-the-loop (HITL) capabilities, dynamic orchestration in plain Go, and a unified node runtime, aligning it closely with the Python ADK's graph-first approach. The graph structure enables real-world applications to handle complex tasks like branching, looping, human approvals, and retries efficiently, while the use of nodes and edges simplifies the representation and execution of workflows. ADK 2.0 also introduces new agent modes and a streamlined programming model that consolidates contexts, making it easier to manage tools, callbacks, and graph nodes. This upgrade from ADK 1.0 is designed to be additive, offering richer event streams and improved resilience features, allowing developers to build robust and scalable agent applications in Go.
