Building Agents with the ADK and the New Interactions API Originally published on Google Developers Blog - December 11, 2025, co-authored with Mike Smith and Xiang (Sean) Zhou. The landscape of AI development is shifting from stateless request-response cycles to stateful, multi-turn agentic interactions. The new Interactions API lets you power ADK agents or connect A2A systems directly to the Gemini Deep Research Agent. Why This Matters Stateful, multi-turn interaction patterns are exactly where agent memory systems earn their keep — this API gives ADK and A2A a standard way to plug into long-running, stateful agent experiences.
