Google has replaced its old generateContent interface with the Interactions API as the default interface for Gemini models and agents. The new API, which is generally available, allows for more flexibility and control. Recent updates include Managed Agents, background execution, tool chaining, and media generation. The API simplifies the schema and offers two modes: Flex and Priority. This change sets the stage for a new era of Agents, enabling more efficient and effective interactions. Why it matters: This shift towards the Interactions API represents a significant step forward for Google’s AI capabilities, enabling more sophisticated and human-like interactions.
