- whatItIs
- Preview API inside Google's open-source Genkit framework that packages agent definitions, session state, streaming, remote clients, human-approval interrupts, HTTP routes, and multi-agent delegation behind a single interface for building full-stack agentic apps. Distinct from Google's Agent Development Kit (already tracked as google-adk): Genkit is a general-purpose GenAI app toolkit that added this agent-specific API, whereas ADK is purpose-built only for multi-agent orchestration.
