What is Google ADK 2.0 Workflow Runtime?

Google ADK 2.0 introduces a Workflow Runtime that transforms agent development from a hierarchical structure to a graph-based architecture. This shift enables more flexible and dynamic agent workflows, allowing developers to build complex agent systems with non-linear execution paths. The new runtime provides improved control flow, better state management, and enhanced capabilities for orchestrating multi-step agent operations.

Key Points

• •ADK 2.0 transitions from hierarchical agent architecture to graph-based workflow design
• •Graph-based approach enables non-linear execution paths and more flexible control flow
• •Workflow Runtime provides improved state management across agent operations
• •Supports complex multi-step agent orchestration with dynamic routing
• •Graph structure allows agents to branch, merge, and loop based on conditions
• •Enhanced flexibility for building sophisticated agent systems beyond linear workflows
• •Graph-based design enables better visualization and debugging of agent flows
• •Supports conditional branching and dynamic decision-making in agent workflows
