Google Launches Interactions API to Replace Traditional AI Prompts with Stateful Session Management

Google launches revolutionary Interactions API that replaces traditional AI prompts with stateful session management, enabling developers to build persistent AI applications with background processing capabilities and explicit context tracking that survives across sessions while reducing costs.

• Google releases new Interactions API as a structured alternative to traditional 'everything prompt' approaches, enabling stateful AI applications with permanent session records and context management
• The API supports asynchronous orchestration of Google's Deep Research agent, allowing developers to initiate long-running research tasks that can analyze web content and synthesize complex reports in the background
• Unlike standard chat loops where state exists only as token history, the Interactions API provides explicit state management through Interaction IDs that maintain full context across sessions while optimizing caching and reducing costs
