An Apache-2.0 Python framework (requires Python 3.11+) for defining agents in code, then evaluating and deploying them. Its 2.0 release adds a graph-based Workflow Runtime for deterministic flows with routing, fan-out/fan-in, loops, and human-in-the-loop, plus a Task API for structured agent-to-agent delegation. Use it when you need orchestrated, controllable multi-agent systems; run them locally via adk run or the adk web UI.
