Orkestrasi Alur Kerja Kerangka Kerja Agen Microsoft - Bersamaan

Orkestrasi bersamaan memungkinkan beberapa agen untuk mengerjakan tugas yang sama secara paralel. Setiap agen memproses input secara independen, dan hasilnya dihimpun dan diagregasi. Pendekatan ini sangat cocok untuk skenario di mana beragam perspektif atau solusi berharga, seperti brainstorming, penalaran ansambel, atau sistem pemungutan suara.

Apa yang akan Anda Pelajari

• Cara menentukan beberapa agen dengan keahlian yang berbeda
• Cara mengatur agen ini untuk bekerja secara bersamaan pada satu tugas
• Cara mengumpulkan dan memproses hasilnya

Dalam orkestrasi bersamaan, beberapa agen bekerja pada tugas yang sama secara bersamaan dan independen, memberikan beragam perspektif pada input yang sama.

Membangun Alur Kerja dengan Pelaksana Kustom

chat_client = AzureChatClient(credential=AzureCliCredential())

researcher = ResearcherExec(chat_client)
marketer = MarketerExec(chat_client)
legal = LegalExec(chat_client)

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

Tingkat Lanjut: Agregator Kustom

Secara default, orkestrasi bersamaan menggabungkan semua respons agen ke dalam daftar pesan. Anda dapat mengambil alih perilaku ini dengan agregator kustom yang memproses hasilnya dengan cara tertentu:

Menentukan Agregator Kustom

# Define a custom aggregator callback that uses the chat client to summarize
async def summarize_results(results: list[Any]) -> str:
    # Extract one final assistant message per agent
    expert_sections: list[str] = []
    for r in results:
        try:
            messages = getattr(r.agent_run_response, "messages", [])
            final_text = messages[-1].text if messages and hasattr(messages[-1], "text") else "(no content)"
            expert_sections.append(f"{getattr(r, 'executor_id', 'expert')}:\n{final_text}")
        except Exception as e:
            expert_sections.append(f"{getattr(r, 'executor_id', 'expert')}: (error: {type(e).__name__}: {e})")

    # Ask the model to synthesize a concise summary of the experts' outputs
    system_msg = ChatMessage(
        Role.SYSTEM,
        text=(
            "You are a helpful assistant that consolidates multiple domain expert outputs "
            "into one cohesive, concise summary with clear takeaways. Keep it under 200 words."
        ),
    )
    user_msg = ChatMessage(Role.USER, text="\n\n".join(expert_sections))

    response = await chat_client.get_response([system_msg, user_msg])
    # Return the model's final assistant text as the completion result
    return response.messages[-1].text if response.messages else ""

Membangun Alur Kerja dengan Agregator Kustom

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

output_evt: WorkflowOutputEvent | None = None
async for event in workflow.run_stream("We are launching a new budget-friendly electric bike for urban commuters."):
    if isinstance(event, WorkflowOutputEvent):
        output_evt = event

if output_evt:
    print("===== Final Consolidated Output =====")
    print(output_evt.data)

Contoh Output dengan Agregator Kustom

===== Final Consolidated Output =====
Urban e-bike demand is rising rapidly due to eco-awareness, urban congestion, and high fuel costs,
with market growth projected at a ~10% CAGR through 2030. Key customer concerns are affordability,
easy maintenance, convenient charging, compact design, and theft protection. Differentiation opportunities
include integrating smart features (GPS, app connectivity), offering subscription or leasing options, and
developing portable, space-saving designs. Partnering with local governments and bike shops can boost visibility.

Risks include price wars eroding margins, regulatory hurdles, battery quality concerns, and heightened expectations
for after-sales support. Accurate, substantiated product claims and transparent marketing (with range disclaimers)
are essential. All e-bikes must comply with local and federal regulations on speed, wattage, safety certification,
and labeling. Clear warranty, safety instructions (especially regarding batteries), and inclusive, accessible
marketing are required. For connected features, data privacy policies and user consents are mandatory.

Effective messaging should target young professionals, students, eco-conscious commuters, and first-time buyers,
emphasizing affordability, convenience, and sustainability. Slogan suggestion: "Charge Ahead—City Commutes Made
Affordable." Legal review in each target market, compliance vetting, and robust customer support policies are
critical before launch.
