Parallel Pattern: Agents Working Simultaneously

~10 min read

Each agent tackles a different subtask at the same time, and their outputs merge into one result — reduces latency in high-throughput pipelines where subtasks don't depend on each other.

Key points

  • Multiple agents tackle genuinely independent subtasks simultaneously, with outputs merged into one final result
  • Only makes sense when subtasks truly don't depend on each other's output — otherwise you're back to Sequential
  • Perfect for reducing latency in high-throughput pipelines like document parsing or API orchestration
  • Total wall-clock time drops to roughly the slowest individual agent's time, not the sum of all agents
  • Requires an explicit aggregation step, and genuine confidence the subtasks are truly independent — mistaken parallelization produces subtly wrong results
