The AI development landscape is shifting from stateless request-response patterns to stateful, multi-turn agentic workflows. Google's new Interactions API provides a unified interface designed specifically for this new era—offering a single gateway to both raw Gemini models and the fully managed Deep Research Agent.

In one sentence: The Interactions API is a unified endpoint for interacting with Gemini models and agents, featuring server-side state management, background execution for long-running tasks, and native support for the Deep Research Agent.

Your agent's instructions are its Standard Operating Procedure (SOP). In Google ADK, this SOP lives in the agent's prompt—the detailed instructions that guide every decision, every tool call, every response.

The problem? Writing the perfect SOP manually is nearly impossible. You add rules to fix failures. Each new rule breaks something else. Your agent becomes unpredictable. Your SOP becomes a mess of band-aids.

The solution? GEPA (Genetic Evolutionary Prompt Augmentation)—automatic SOP optimization that learns from failures and evolves better instructions through real testing.
