Architecture Categories

Linear Architectures

These architectures execute tasks in a straightforward manner:
  • Sequential Workflow: Agents execute in order (A → B → C)
  • Concurrent Workflow: Agents execute simultaneously on the same task

Dynamic Architectures

These provide flexible orchestration patterns:
  • Agent Rearrange: Define custom flows with → and , operators
  • Swarm Router: Dynamically select and execute any swarm type
  • Social Algorithms: Upload arbitrary communication patterns

Hierarchical Architectures

These implement structured command patterns:
  • Hierarchical Swarm: Director coordinates specialized workers
  • Heavy Swarm: 5-phase workflow with question generation

Collaborative Architectures

These enable agent interaction and synthesis:
  • Mixture of Agents: Parallel experts with aggregation
  • Group Chat: Conversational multi-agent interaction
  • Graph Workflow: DAG-based complex workflows

Choosing the Right Architecture

1

Identify Your Pattern

Determine if your task needs sequential, parallel, or mixed execution
2

Consider Complexity

Match architecture complexity to task requirements
3

Evaluate Features

Review specific features like feedback loops, aggregation, or dynamic routing
4

Test and Iterate

Start simple and upgrade to more complex architectures as needed
