Today we’re announcing that the Interactions API has reached general availability and is now our primary API for interacting with Gemini models and agents. We launched its public beta in December 2025, and it has quickly become developers’ favorite way to build applications with Gemini.
With this GA release, the API now has a stable schema and we also added major new capabilities that developers asked for, including Managed Agents, background execution, Gemini Omni (soon) and more. All of our documentation now defaults to Interactions API and we are working with ecosystem partners to make it the default interface across 3P SDKs and Libraries.
The simplest way to build with Gemini
Whether you’re calling a model or running an agent, the Interactions API gets you there in a few lines of code. Pass a model ID for inference, an agent ID for autonomous tasks, set background=True for anything long-running.
