In detail
- Interactions API moves out of beta (beta since Dec 2025) and becomes the default in Google AI Studio and documentation.
- The old generateContent API remains functional but new agent features will only ship via Interactions.
- New capabilities: Managed Agents with their own Linux sandbox, background execution for long‑running tasks, tool chaining with Google Search and Maps, and media generation (images, music, speech).
- Schema simplified: old role labels replaced by typed steps; developers can choose Flex (≈50% cost reduction) or Priority (speed optimized).
Why it matters
Standardizing on one API shapes how businesses integrate Gemini agents and unlocks new agent features and cost/speed tradeoffs important for production deployments.
For you Audit any generateContent usage and schedule migration testing; evaluate Flex mode to cut API costs for non‑latency critical tasks.
