Interactions API

Interactions API is Google's primary API interface for Gemini models and agents, designed around stateful, typed-step, agentic workflows rather than one-off model calls [src-143].

Key facts

  • Publisher: Google
  • Product surface: Google AI Studio, Gemini API, and Google documentation default to Interactions API [src-143].
  • Agent features: Google highlights typed steps, managed agents, background execution, past-interaction retrieval, and cost/latency tiers [src-143].
  • Migration signal: Google says the legacy generateContent API remains supported, but expects future long-running model and agent capabilities to increasingly land on Interactions API [src-143].

Robin Cartier perspective

This page is part of Robin Cartier's working AI knowledge graph: a practical research layer for production AI, recommendation systems, experimentation, GEO, and agentic web readiness.

The useful next step is to connect this concept back to applied product leadership and operating models.
