Architecture
A hierarchical multi-agent architecture that scales orchestration by stacking supervisors and team leads (a tree structure), which mirrors enterprise org structures and helps partition context. This is the 'enterprise-grade agentic AI architecture' when a single orchestrator cannot manage all workers directly. Ideal for large enterprises and multi-domain workflows.
User { # User
n1: circle label:"Start"
n2: rectangle label:"Submit enterprise request"
n1.handle(right) -> n2.handle(left)
n2.handle(bottom) -> Supervisor.n3.handle(top) [label="Goal"]
}
Supervisor { # Top-Level Supervisor
n3: rectangle label:"Decompose goal"
n4: rectangle label:"Delegate to team leads"
n5: rectangle label:"Aggregate final output"
n6: circle label:"Done"
n3.handle(right) -> n4.handle(left)

Workers { # Worker Agents
n13: rectangle label:"Worker A1 executes"
n14: rectangle label:"Worker A2 executes"
n15: rectangle label:"Worker B1 executes"
n16: rectangle label:"Worker B2 executes"
n13.handle(top) -> LeadA.n9.handle(bottom) [label="A1 done"]
n14.handle(top) -> LeadA.n9.handle(bottom) [label="A2 done"]

Architecture
An orchestrator-worker architecture where an orchestrator agent breaks a goal into subtasks, dispatches to specialized workers, then synthesizes a final response. This is the most common 'agent orchestration' architecture—powerful but the orchestrator can become a bottleneck as the number of workers grows. Frameworks like LangGraph focus on explicit routing/state to manage this.
Architecture
A competitive / generator-critic architecture where multiple generators produce independent answers, then an evaluator agent scores and selects the best output. This approach improves quality and reduces single-model brittleness. It's costlier (multiple LLM calls) but pays off when correctness or creativity matters more than latency.
Architecture
A single-agent AI architecture where one agent handles everything: parsing requests, reasoning, calling tools via MCP, and generating responses. This is the default architecture for prototypes and simple automations—easy to debug but hits context-window limits quickly and is hard to parallelize. Ideal for MVPs and solo builders shipping fast.
Architecture
A sequential pipeline architecture chaining multiple agents in a fixed order (parse → enrich → analyze → format), which is a common 'LLM microservices' setup when each step can be isolated. This structure is often used in document processing and ETL-like workflows because each step is testable and predictable.
Architecture
A parallel fan-out architecture that runs multiple agents simultaneously on independent checks (style, security, performance) and then merges results. This is a standard multi-agent design approach for throughput, mapping cleanly to CI/CD, incident response, and research. Fan-in reconciliation becomes the subtle part.
Architecture
An event-driven agentic AI architecture that replaces the central orchestrator with Kafka/PubSub topics: agents subscribe, react, and publish new events. This aligns multi-agent systems with proven microservices choreography and is ideal for real-time, high-throughput systems and 'agent mesh' setups.
