AutoGen 架構模式
1.1 简单对话模式
適用場景:單一智能体處理用戶查詢
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
async def main():
model_client = OpenAIChatCompletionClient(model="gpt-5.4")
agent = AssistantAgent("assistant", model_client=model_client)
result = await agent.run(task="Get weather in San Francisco")
print(result)
await model_client.close()
優缺點分析:
- ✅ 簡單易用:代碼量少,上手快
- ❌ 能力受限:無法處理複雜任務
- 成本門檻:單次 API 調用成本
1.2 多智能体协作模式
適用場景:多步驟任務協作,需要不同專長的智能体
from autogen_agentchat.agents import AssistantAgent, UserProxyAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
from autogen_ext.tools.mcp import McpWorkbench, StdioServerParams
async def main():
model_client = OpenAIChatCompletionClient(model="gpt-5.4")
# 智能体 1:分析任務
analyst = AssistantAgent("analyst", model_client=model_client)
# 智能体 2:執行任務
executor = AssistantAgent("executor", model_client=model_client)
# 工作台:協調工具
async with McpWorkbench(StdioServerParams("npx", ["@playwright/mcp@latest"])) as mcp:
executor.workbench = mcp
# 協作流程
analysis = await analyst.run("Analyze the user request")
execution = await executor.run(f"Execute based on: {analysis}")
await model_client.close()
優缺點分析:
- ✅ 能力增強:專分工能分工明確

async def main():
assistant = AssistantAgent("assistant", model_client=model_client)
# 用户代理等待人工确认
user_proxy = UserProxyAgent(
"user_proxy",
user_input="Do you approve this response?",
human_input_method="TERMINATE"
)
# 协作流程
response = await assistant.run("Generate a response")
confirmation = await user_proxy.run(response)
優缺點分析:
- ✅ 可控性強:人工審核保證質量
- ❌ 延遲增加:等待人工確認
- 吞吐量限制:依賴人工可用性
生产部署策略
2.1 模型选择策略
成本優化模式:
- 小模型處理簡單任務:GPT-5.4-mini
- 大模型處理複雜任務:GPT-5.4
- 專用模型:Claude Opus 4.7(特定領域)
示例:
# 簡單查詢 → 小模型
if user_input.is_simple_query():
model = "gpt-5.4-mini"
else:
model = "gpt-5.4"
性能門檻:
- 小模型響應時間:< 1 秒
- 大模型響應時間:< 5 秒
- 錯誤率 < 1%
2.2 MCP 工具管理
工具選擇原則:
- 優先官方 MCP 服務器:@playwright/mcp, @curl/mcp
- 驗證工具輸出:僅信任可驗證的輸出
- 限制工具調用次數:max_tool_iterations=10
示例:
server_params = StdioServerParams(
command="npx",
args=["@playwright/mcp@latest", "--headless"]
)
安全考量:
- ❌ 禁止執行系統命令:防止惡意行為
- ✅ 僅使用受信任工具:官方 MCP 服務器
- ✅ 驗證輸出:檢查工具返回結果
2.3 错误处理和重试
重試策略:
max_retries = 3
retry_delay = 1 # 秒
for attempt in range(max_retries):
try:
result = await agent.run(task)
break
except Exception as e:
if attempt == max_retries - 1:
raise
await asyncio.sleep(retry_delay)
故障隔离:
- 智能体级隔离:單個智能体失敗不影響其他
- 任務级隔离:失敗任務重新調度
- 全局级容錯:降級到簡單模式
安全和治理
3.1 输入验证和过滤
敏感词过滤:
sensitive_keywords = ["credit_card", "password", "api_key"]
def validate_input(user_input):
for keyword in sensitive_keywords:
if keyword in user_input.lower():
raise ValueError(f"Sensitive content detected: {keyword}")
return True
输出审查:
- 人工审核模式:生產環境必須人工確認
- 自动过滤模式:仅限非关键场景
- 二次验证:关键输出需人工审核
3.2 隐私保护
数据访问控制:
# Agent Lee 模式:僅訪問授權數據
allowed_data = {
"zone_settings": True,
"dns_records": True,
"security_rules": True
}
def check_data_access(data_type):
return allowed_data.get(data_type, False)
不應訪問的数据:
- ❌ 支付信息:信用卡、账單
- ❌ API 密钥:OpenAI、Anthropic
- ❌ 原始日志:日誌數據、Logpush
3.3 合规性检查
法律合规:
- GDPR 合规:數據處理同意
- FTC 指導:消费者保护
- SEC 法規:投资建议限制
示例:
def compliance_check(response):
# 棢查投資建議
if contains_investment_advice(response):
raise ComplianceError("Investment advice requires licensed advisor")
# 檢查醫療建議
if contains_medical_recommendation(response):
raise ComplianceError("Medical advice requires licensed physician")
可观测性指标
4.1 关键指标
实时指标:
- 智能体活跃度:每秒調用次数
- 任务完成率:成功完成 vs 失败
- 平均響應時間:P50, P95, P99
示例:
# Prometheus 指标
agent_active_count = gauge("agent_active_count", {"agent_id": "assistant"})
task_completion_rate = gauge("task_completion_rate", {"agent_id": "executor"})
avg_response_time = histogram("response_time_seconds", {"agent_id": "analyst"})
4.2 成本追踪
成本分解:
- 模型调用成本:GPT-5.4, Claude Opus 4.7
- 工具调用成本:MCP 服務器
- 存储成本:對話歷史、上下文
成本优化:
# 成本預算
daily_budget = 100 # 美元
model_cost_per_1k_tokens = {
"gpt-5.4-mini": 0.50,
"gpt-5.4": 2.00,
"claude-opus-4.7": 5.00
}
def estimate_cost(user_input):
tokens = estimate_tokens(user_input)
model = select_model(user_input)
return (tokens / 1000) * model_cost_per_1k_tokens[model]
4.3 异常检测
异常模式识别:
- 异常响应时间:> 5 秒
- 异常错误率:> 5%
- 异常调用频率:> 100 次/秒
告警规则:
def check_alerts(metrics):
alerts = []
if metrics["p99_response_time"] > 5:
alerts.append("High latency detected")
if metrics["error_rate"] > 0.05:
alerts.append("High error rate detected")
return alerts

Core Topic: Build production-grade multi-agent systems using Microsoft AutoGen, from architectural patterns to deployment strategies.
Introduction: Why AutoGen is suitable for production-level multi-agent systems
In 2026, a single agent will no longer be able to meet the needs of complex business scenarios. Multi-agent collaboration has become an inevitable choice, and AutoGen provides a mature framework to achieve this goal.
AutoGen’s Core Benefits:
- Out-of-the-box multi-agent architecture: Designed for multi-agent collaboration
- Native MCP support: can connect external tools and services
- Production Ready: Microsoft maintenance model, community driven
- Scalability: Supports simple to complex scenarios
Key Features:
- AssistantAgent: the agent that performs the task
- UserProxyAgent: simulate user interaction
- MCP Workbench: Tool Coordinator
- Streaming Execution: real-time output and tracking
AutoGen Architecture Pattern
1.1 Simple dialogue mode
Applicable scenario: A single agent handles user queries
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
async def main():
model_client = OpenAIChatCompletionClient(model="gpt-5.4")
agent = AssistantAgent("assistant", model_client=model_client)
result = await agent.run(task="Get weather in San Francisco")
print(result)
await model_client.close()
Advantages and Disadvantages Analysis:
- ✅ Easy to use: less code, quick to get started
- ❌ Limited Ability: Unable to handle complex tasks
- Cost Threshold: Cost of a single API call
1.2 Multi-agent collaboration model
Applicable scenarios: Multi-step task collaboration, requiring agents with different expertise
from autogen_agentchat.agents import AssistantAgent, UserProxyAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
from autogen_ext.tools.mcp import McpWorkbench, StdioServerParams
async def main():
model_client = OpenAIChatCompletionClient(model="gpt-5.4")
# 智能体 1:分析任務
analyst = AssistantAgent("analyst", model_client=model_client)
# 智能体 2:執行任務
executor = AssistantAgent("executor", model_client=model_client)
# 工作台:協調工具
async with McpWorkbench(StdioServerParams("npx", ["@playwright/mcp@latest"])) as mcp:
executor.workbench = mcp
# 協作流程
analysis = await analyst.run("Analyze the user request")
execution = await executor.run(f"Execute based on: {analysis}")
await model_client.close()
Advantages and Disadvantages Analysis:
- ✅ Ability enhancement: Specialized division of labor can be clearly divided
- ❌ Coordination Complex: Communication cost between agents
- Communication Overhead: API cost per agent interaction
1.3 User agent mode
Applicable scenarios: Scenarios that require human feedback and confirmation
from autogen_agentchat.agents import AssistantAgent, UserProxyAgent
async def main():
assistant = AssistantAgent("assistant", model_client=model_client)
# 用户代理等待人工确认
user_proxy = UserProxyAgent(
"user_proxy",
user_input="Do you approve this response?",
human_input_method="TERMINATE"
)
# 协作流程
response = await assistant.run("Generate a response")
confirmation = await user_proxy.run(response)
Advantages and Disadvantages Analysis:
- ✅ Strong controllability: Manual review to ensure quality
- ❌ Delay Increase: Waiting for manual confirmation
- Throughput Limit: Dependent on human availability
Production deployment strategy
2.1 Model selection strategy
Cost Optimization Mode:
- Small model for simple tasks: GPT-5.4-mini
- Large models handle complex tasks: GPT-5.4
- Specialized Model: Claude Opus 4.7 (domain specific)
Example:
# 簡單查詢 → 小模型
if user_input.is_simple_query():
model = "gpt-5.4-mini"
else:
model = "gpt-5.4"
Performance Threshold:
- Small model response time: < 1 second
- Large model response time: < 5 seconds
- Error rate < 1%
2.2 MCP Tool Management
Tool Selection Principles:
- Official MCP Servers Prioritized: @playwright/mcp, @curl/mcp
- Validation Tool Output: Only trust verifiable output
- Limit the number of tool calls: max_tool_iterations=10
Example:
server_params = StdioServerParams(
command="npx",
args=["@playwright/mcp@latest", "--headless"]
)
Safety Considerations:
- ❌ Prohibit execution of system commands: Prevent malicious behavior
- ✅ Only use trusted tools: Official MCP Servers
- ✅ Validation Output: Check tool returns results
2.3 Error handling and retry
Retry Strategy:
max_retries = 3
retry_delay = 1 # 秒
for attempt in range(max_retries):
try:
result = await agent.run(task)
break
except Exception as e:
if attempt == max_retries - 1:
raise
await asyncio.sleep(retry_delay)
Fault Isolation:
- Agent Level Isolation: The failure of a single agent does not affect other
- Task Level Isolation: Failed tasks rescheduled
- Global Level Fault Tolerance: downgrade to simple mode
Security and Governance
3.1 Input validation and filtering
Sensitive word filter:
sensitive_keywords = ["credit_card", "password", "api_key"]
def validate_input(user_input):
for keyword in sensitive_keywords:
if keyword in user_input.lower():
raise ValueError(f"Sensitive content detected: {keyword}")
return True
Output review:
- Manual review mode: The production environment must be manually confirmed
- Auto filter mode: non-critical scenes only
- Second Verification: Key outputs require manual review
3.2 Privacy Protection
Data Access Control:
# Agent Lee 模式:僅訪問授權數據
allowed_data = {
"zone_settings": True,
"dns_records": True,
"security_rules": True
}
def check_data_access(data_type):
return allowed_data.get(data_type, False)
Data that should not be accessed:
- ❌ Payment Information: Credit card, bill
- ❌ API Key: OpenAI, Anthropic
- ❌ Original log: Log data, Logpush
3.3 Compliance Check
Legal Compliance:
- GDPR Compliance: Consent to Data Processing
- FTC Guidance: Consumer Protection
- SEC Regulation: Investment Advice Restrictions
Example:
def compliance_check(response):
# 棢查投資建議
if contains_investment_advice(response):
raise ComplianceError("Investment advice requires licensed advisor")
# 檢查醫療建議
if contains_medical_recommendation(response):
raise ComplianceError("Medical advice requires licensed physician")
Observability indicators
4.1 Key Indicators
Real-time Metrics:
- Agent Activity: Number of calls per second
- Task Completion Rate: Successfully completed vs. failed
- Average response time: P50, P95, P99
Example:
# Prometheus 指标
agent_active_count = gauge("agent_active_count", {"agent_id": "assistant"})
task_completion_rate = gauge("task_completion_rate", {"agent_id": "executor"})
avg_response_time = histogram("response_time_seconds", {"agent_id": "analyst"})
4.2 Cost Tracking
Cost breakdown:
- Model calling cost: GPT-5.4, Claude Opus 4.7
- Tool Call Cost: MCP Server
- Storage Cost: Conversation history, context
Cost Optimization:
# 成本預算
daily_budget = 100 # 美元
model_cost_per_1k_tokens = {
"gpt-5.4-mini": 0.50,
"gpt-5.4": 2.00,
"claude-opus-4.7": 5.00
}
def estimate_cost(user_input):
tokens = estimate_tokens(user_input)
model = select_model(user_input)
return (tokens / 1000) * model_cost_per_1k_tokens[model]
4.3 Anomaly detection
Abnormal Pattern Recognition:
- Exception response time: > 5 seconds
- Exception error rate: > 5%
- Exception call frequency: > 100 times/second
Alarm rules:
def check_alerts(metrics):
alerts = []
if metrics["p99_response_time"] > 5:
alerts.append("High latency detected")
if metrics["error_rate"] > 0.05:
alerts.append("High error rate detected")
return alerts
