# Agent Framework's Five Orchestration Patterns: Which One for Your Multi-Agent App

> Sequential, Concurrent, Group Chat, Handoff, Magentic. The real question every pattern answers is the same one — who decides which agent goes next — and the answer trades control for autonomy.

## Key takeaways

- Microsoft Agent Framework ships five built-in multi-agent orchestration patterns, and the choice between them reduces to one question: who picks the next agent to run?
- Sequential — you do, at build time (a fixed pipeline). Concurrent — nobody; all agents run in parallel on the same input and results are aggregated. Group Chat — a turn policy rotates the floor among agents in a shared transcript. Handoff — the current agent decides, transferring control based on context. Magentic — a manager LLM plans the round-by-round coordination dynamically.
- The axis is control vs. autonomy: Sequential and Concurrent are deterministic and cheap to debug; Handoff and Magentic are adaptive but spend more tokens and are harder to trace.
- All five support streaming, checkpointing, and human-in-the-loop pause/resume, so you can start deterministic and add autonomy where it earns its keep.
- Default advice: reach for Concurrent or Sequential first; escalate to Handoff or Magentic only when a fixed graph genuinely can't express the routing.

## At a glance

| Pattern | Who picks the next agent | Determinism | Best for | Cost / latency |
| --- | --- | --- | --- | --- |
| Sequential | You, at build time | Fully deterministic | Fixed pipelines (draft → review → refine) | Low; sum of steps |
| Concurrent | Nobody — all run at once | Deterministic fan-out | Independent perspectives on one input | Low latency, higher token spend (parallel) |
| Group Chat | A turn/round policy | Semi-deterministic | Collaborative drafting in a shared transcript | Medium; grows with rounds |
| Handoff | The current agent (by context) | Non-deterministic | Routing/triage where the path depends on input | Medium; depends on hops |
| Magentic | A manager LLM, round by round | Least deterministic | Open-ended tasks needing dynamic planning | Highest; manager + workers per round |

Every [multi-agent](/topics/agent-frameworks) framework eventually makes you answer the same question, and most of them bury it: **who decides which agent runs next?** [Microsoft Agent Framework](/posts/semantic-kernel-vs-autogen-vs-microsoft-agent-framework.html) at least makes the answer explicit — it ships five orchestration patterns, and each one is just a different answer to that single question. Get the framing right and the choice stops being a menu and becomes a decision tree.
The one axis that matters: control vs. autonomy
Line the five patterns up by *who holds the routing decision* and they sort themselves from most-controlled to most-autonomous:
- **Sequential** — *you* decide, at build time. A fixed order: agent A, then B, then C.
- **Concurrent** — *nobody* decides. Every agent runs in parallel on the same input; results are aggregated.
- **Group Chat** — a *turn policy* decides, rotating the floor among agents in one shared transcript.
- **Handoff** — the *current agent* decides, transferring control to another agent based on context.
- **Magentic** — a *manager LLM* decides, planning the round-by-round coordination dynamically.

That ordering is also, not coincidentally, the order of increasing token cost and decreasing debuggability. Every step you move toward autonomy, you hand the routing to the model — which is powerful exactly where a fixed graph can't express the path, and a liability exactly where it can.
The two you'll reach for first
**Concurrent** is the workhorse and the one most teams under-use. When you want several independent perspectives on the same input — a researcher, a marketer, and a legal reviewer all reacting to one product brief — you don't need them talking to each other. You need them running at once and their outputs merged. The API is deliberately small:
```
import os
from agent_framework.foundry import FoundryChatClient
from agent_framework.orchestrations import ConcurrentBuilder
from agent_framework import Message
from azure.identity import AzureCliCredential
from typing import cast

chat_client = FoundryChatClient(
    project_endpoint=os.environ["FOUNDRY_PROJECT_ENDPOINT"],
    model=os.environ["FOUNDRY_MODEL"],
    credential=AzureCliCredential(),
)

researcher = chat_client.as_agent(
    instructions="Expert market and product researcher. Give concise insights, opportunities, and risks.",
    name="researcher",
)
# ...marketer and legal defined the same way

workflow = ConcurrentBuilder(participants=[researcher, marketer, legal]).build()

output: list[Message] | None = None
async for event in workflow.run("We're launching a budget e-bike for urban commuters.", stream=True):
    if event.type == "output":
        output = event.data

for i, msg in enumerate(cast(list[Message], output or []), start=1):
    name = msg.author_name or "user"
    print(f"{i:02d} [{name}]:\n{msg.text}")
```
Note the shape: you build with `ConcurrentBuilder(participants=[...]).build()` and consume `event.type == "output"` off a streamed `workflow.run(...)`. The other builders — `SequentialBuilder`, `GroupChatBuilder`, `HandoffBuilder`, `MagenticBuilder` — follow the same *build-then-run* rhythm, which is the point: swapping patterns is a one-line change, not a rewrite.
**Sequential** is the other default. If you already know the order — draft, then critique, then revise — encode it. You get a fully deterministic pipeline that's trivial to trace and cheap to run, because control flow never depends on model output. Most "agentic" workflows that ship to production are Sequential wearing a fancier name.
> If you can draw the graph before you run it, you don't need a model to route it. Reserve the autonomous patterns for the cases where you genuinely can't.

The three that spend tokens for adaptivity
**Group Chat** puts agents in one shared transcript and lets a turn policy rotate who speaks. Use it when the *collaboration itself* is the product — several agents refining a document together, each seeing the others' contributions. It costs more than Concurrent because the transcript grows every round.
**Handoff** lets the active agent transfer control based on context — the pattern behind triage and routing. A front-line agent inspects the request and hands off to billing, or tech support, or escalation. This is the same idea as [agent handoffs in LangGraph and the OpenAI/Google SDKs](/posts/agent-handoffs-langgraph-openai-adk.html): the routing is data-dependent, so you let the model make it. Powerful for support-style flows; non-deterministic by nature, so instrument every hop.
**Magentic** is the most autonomous, drawn from Microsoft's Magentic-One research. A manager agent owns the coordination: it plans, delegates to specialist workers, and tracks progress round by round, bounded by configurable max-round and stall/reset limits so it can't spin forever. Reach for it when the task is open-ended enough that *you can't pre-plan the steps* — but know you're paying for the manager's reasoning on top of every worker call. It's the pattern most likely to impress in a demo and most likely to surprise you on the invoice.
The rule of thumb
Start with the most constrained pattern that expresses your problem, and escalate only when it can't route correctly. Concrete order of preference: **Sequential or Concurrent → Group Chat → Handoff → Magentic.** Because all five support streaming, checkpointing, and human-in-the-loop pause/resume, you can also mix — a deterministic Sequential spine with a Magentic step in the one place that needs open-ended planning. If you're still choosing a framework at all, this orchestration surface is a good part of the [broader multi-agent comparison](/posts/agno-vs-langgraph-vs-crewai.html): the patterns are similar everywhere, but MAF is unusually explicit about naming them — and that clarity is worth something at 3 a.m. when a workflow won't route.

## FAQ

### How do I choose between these patterns?

Ask who should decide the next step. If you know the order at build time, use Sequential. If several agents should weigh in independently on the same input, use Concurrent. If they should collaborate in one transcript, use Group Chat. If the path depends on the input and the current agent knows best, use Handoff. If the task is open-ended enough that a planner must coordinate specialists on the fly, use Magentic.

### What is the Magentic pattern?

Magentic (from Microsoft's Magentic-One research) uses a manager agent that owns round-by-round coordination — it plans, delegates to specialist agents, and tracks progress with configurable max-round and stall/reset limits so it can't loop forever. It's the most autonomous and the most expensive: you're paying for the manager's reasoning on top of the workers'.

### Are these patterns deterministic?

Sequential and Concurrent are effectively deterministic in control flow (the routing doesn't change with the model's output). Group Chat is semi-deterministic via its turn policy. Handoff and Magentic are non-deterministic by design — the model decides the path — which is exactly what makes them powerful and harder to debug.

### Can I add a human approval step?

Yes. Agent Framework's orchestrations support streaming, checkpointing, and human-in-the-loop pause/resume, so you can gate a handoff or a Magentic round on human approval without abandoning the pattern.

### Should I use Magentic for everything?

No. More autonomy costs more tokens and makes traces harder to read. Start with the most constrained pattern that expresses your problem and escalate only when a fixed graph can't route correctly.
