[Advent of Agents] Day 10: Multi-Agent Patterns: Parallel Fanout and State Interpolation

[abraha...@google.com]

Hi everyone,

Day 10 of Google's Advent of Agents — Season 2 is now live!

Stop waiting for sequential LLM calls to finish one by one and start running your agentic workflows in parallel. Learn how to use Parallel Fanout and State Interpolation to slash latency while maintaining seamless data synthesis across your agents.

Today's Highlights:

• Execute multiple independent agents simultaneously with ParallelAgent to dramatically reduce wall-clock time.
• Map agent outputs directly to session state using the output_key feature for automated data management.
• Synthesize results using State Interpolation, allowing downstream agents to access data via simple bracket templating.
