Google announced the Interactions API as the new GA interface for Gemini. It adds server-side state, background execution, and visible execution steps, making models and agents easier to build together.
What happened
Google made the Gemini API Interactions API GA and the recommended path for new development. It improves handling of conversation state and long-running tasks, and brings model calls and agent workflows closer together.
Why it matters
A clearer API surface reduces decision fatigue for developers. Background execution and visible steps also help with long jobs, debugging, and UI design.
Impact for users
Builders of Gemini chatbots and work agents can design multi-step flows more naturally. Since generateContent is still supported, there is no urgent need to migrate everything at once.
