Multi-agent architectures are the FUTURE

Here are 6 different types:

1. Hierarchical (Vertical) Architecture A supervisor agent orchestrates multiple specialized agents. Example: • One agent retrieves information from internal data sources • Another agent specializes in public information from web searches • A third agent specializes in retrieving information from personal accounts (email, chat)

2. Human-in-the-Loop Architecture Incorporates human verification before proceeding to next actions, used when handling sensitive information.

3/5. Network (Horizontal) Architecture Agents communicate directly with one another in a many-to-many fashion. Forms a decentralized network without strict hierarchical structure.

4. Sequential Architecture Agents process tasks in sequence, where one agent's output becomes input for the next. Example: Three sequential agents where: • First query agent retrieves information from vector search • Second query agent retrieves additional information from web search based on first agent's findings • Final generation agent creates a response using information from both query agents

5. Data Transformation Architecture Includes agents dedicated to transforming data. Example: • A transformation agent that enriches data at insert-time or transforms existing collections

There are also some other patterns that can be combined with these architectures: • Loop pattern: Iterative cycles for continuous improvement • Parallel pattern: Multiple agents working simultaneously on different parts of a task • Router pattern: A central router determining which agents to invoke • Aggregator/synthesizer pattern: Collecting and synthesizing outputs from multiple agents
