Next-gen agent development is here. ADK 2.0 is a ground-up evolution of the Agent Development Kit, aimed at making it far easier to build reliable, production-grade multi-agent applications.

Why This Matters

Building agents at scale exposes gaps that don’t show up in prototypes: orchestration across many agents, human-in-the-loop checkpoints, dynamic routing, and resilience against failures. ADK 2.0 addresses these head on with a unified runtime and clearer primitives for composing complex agent workflows.

This work is directly relevant to the agent memory and runtime infrastructure I focus on at Google — the same principles of composability and resilience apply whether you’re orchestrating agents or the memory systems underneath them.
