前言:两种不同的架构思维
在 2026 年,AI Agent 系统的构建不再是单一维度的选择——要么使用框架,要么自己造轮子。真正的问题在于:你的需求属于哪一类?
本文对比两种截然不同的架构思维:
- 架构模式(Architecture Patterns):关注系统的结构、组件关系、数据流和控制流设计
- 框架模式(Framework Patterns):关注使用现有框架的组件抽象、API 设计和约定
这两个维度不是互斥的,但它们代表了不同的设计哲学和不同的权衡空间。
核心区别:架构模式 vs 框架模式
架构模式(Architecture Patterns)
关注点:系统的结构设计
核心问题:
- 数据如何流动?
- 控制流如何编排?
- 组件如何解耦?
- 边界在哪里?
典型模式:
- ReAct 循环:观察 → 思考 → 行动
- 工具模式:Agent → Tool → Result
- Checkpoint 恢复模式:状态快照 → 恢复点 → 重放
- 沙箱隔离模式:受限执行环境
- 网关/侧车模式:控制面 vs 数据面
示例:
Agent → Checkpoint → Memory → Tool → Result → Decision
框架模式(Framework Patterns)
关注点:使用框架的约定和抽象
核心问题:
- 框架的 API 设计是否匹配需求?
- 约定是否带来隐式成本?
- 抽象是否足够灵活?
典型模式:
- SDK 约定模式:使用 OpenAI Agents SDK 的约定
- Agent 定义模式:框架的 Agent DSL
- 工具注册模式:框架的工具注册机制
- 事件循环模式:框架的事件驱动设计
示例:
from openai.agents import Agent
agent = Agent(
tools=[],
runtime="gateway" # 网关模式
)

Preface: Two different architectural thinking
In 2026, building an AI Agent system is no longer a one-dimensional choice—either use a framework or build your own wheel. The real question is: **Which category do your needs fall into? **
This article compares two completely different architectural thinking:
- Architecture Patterns: Focus on the structure, component relationships, data flow and control flow design of the system
- Framework Patterns: Focus on component abstraction, API design and conventions using existing frameworks
These two dimensions are not mutually exclusive, but they represent different design philosophies and different trade-off spaces.
Core difference: architectural pattern vs framework pattern
Architecture Patterns
Focus: System structural design
Core question:
- How does data flow?
- How to arrange the control flow?
- How to decouple components?
- Where are the boundaries?
Typical Mode:
- ReAct loop: Observe → Think → Act
- Tool Mode: Agent → Tool → Result
- Checkpoint Recovery Mode: State Snapshot → Recovery Point → Replay
- Sandbox Isolation Mode: Restricted execution environment
- Gateway/Sidecar Mode: Control plane vs data plane
Example:
Agent → Checkpoint → Memory → Tool → Result → Decision
Framework Patterns
Focus: Using framework conventions and abstractions
Core question:
- Does the framework’s API design match the requirements? -Does the agreement bring with it implicit costs?
- Is the abstraction flexible enough?
Typical Mode:
- SDK Convention Mode: Use the convention of OpenAI Agents SDK
- Agent definition mode: Agent DSL of the framework
- Tool Registration Mode: The framework’s tool registration mechanism
- Event Loop Pattern: Event-driven design of the framework
Example:
from openai.agents import Agent
agent = Agent(
tools=[],
runtime="gateway" # 网关模式
)
Key trade-offs: When to choose which?

Migration paths: how to choose and switch
Step 1: Assess needs
Question:

- Do you need precise control over execution flow?
- Does your team have complex system design capabilities?
Decision Tree:

├─ 是 → 评估架构模式优先
└─ 否 → 评估框架模式优先
Step 2: Choose a hybrid strategy
Strategy A: Architecture mode is the main priority
- Customized core architecture -Conventions for using frameworks
- Use the framework’s built-in tools
Strategy B: Mainly frame mode
- Use all conventions of the framework
- Customize within the boundaries of the frame
- Expand using the framework’s built-in capabilities
Step 3: Gradual migration
Migration Path 1:
框架模式 → 增加架构模式 → 混合模式
Migration Path 2:
架构模式 → 适配框架 → 混合模式
