Google DeepMind announces the public beta launch of the Interactions API, accessible through the Gemini API in Google AI Studio. This new interface offers a unified entry point for interacting with models such as Gemini and AI agents.
The API addresses the limitations of existing approaches by offering several key capabilities. First, server-side state management becomes optional, significantly reducing client-side code complexity. Developers no longer need to maintain the full conversation history locally.
Second, the API provides interpretable data structures for managing complex agent histories. The schema natively supports interleaved messages and multiple tool calls, facilitating the construction of sophisticated workflows.
Third, background execution capabilities enable long-running inference without maintaining persistent connections. This architecture is particularly suited to the "extended thinking" tasks that characterize modern agents.
Fourth, native support for the MCP (Model Context Protocol) protocol enables the integration of remote tools in a standardized way. This interoperability facilitates the composition of agents using external services.
The announcement also includes the availability of Gemini Deep Research in preview, a built-in research agent accessible directly through the API. This agent illustrates the direction Google is taking: models are evolving into complete systems capable of autonomous reasoning.
Developers note that this release is only a beginning, with plans to expand built-in agents and support custom agent development. The API is positioned as complementary to the existing generateContent endpoint, which remains recommended for standard production workloads requiring direct responses.
Integration is already available via the Agent Development Kit (ADK) and the Agent2Agent (A2A) protocol, with broader ecosystem adoption expected soon. This announcement is part of the broader industry trend toward standardized interfaces for agents, joining other players' efforts around the MCP protocol.
