The Interactions API enhances the generateContent functionality, catering to modern agentic applications. It features optional server-side state management, simplifying client code and enhancing cache efficiency. The API introduces an interpretable and composable data model, allowing for in-depth debugging and reasoning over complex interaction histories involving messages, tools, and results. Background execution capabilities enable long-running tasks to occur on the server side, streamlining performance. Additionally, it supports remote Model Context Protocol (MCP) tools, enabling direct model interactions.
The API is motivated by evolving model capabilities, transitioning from simple text generation to advanced agent functionalities. While in public beta, it maintains robust support for generateContent features, aimed at easing the deployment of agent applications. Developers can utilize their Gemini API key from Google AI Studio to explore the API, and the Agent Development Kit (ADK) along with the Agent2Agent (A2A) protocol now includes Interactions API support. Engage with the beta and provide feedback to optimize performance.
