# 从 AgentNetwork 迁移到 `.network()`

从 `@mastra/core` 的 `v0.20.0` 版本开始，以下变更生效。

## 从 AI SDK v4 升级到 v5

- 将所有模型 Provider 包升级一个主版本。

> **备注:** 这样可以确保它们现在都是 v5 模型。

## 必须配置 Memory

- Agent 网络现在必须有 Memory 才能正常运行。

> **备注:** 你必须为 Agent 配置 Memory。

## 迁移路径

如果你之前使用 `AgentNetwork` 原语，可以用 `Agent` 替换 `AgentNetwork`。

迁移前：

```typescript
import { AgentNetwork } from '@mastra/core/network'

const agent = new AgentNetwork({
  name: 'agent-network',
  agents: [agent1, agent2],
  tools: { tool1, tool2 },
  model: 'openai/gpt-5.6-sol',
  instructions: 'You are a network agent that can help users with a variety of tasks.',
})

await agent.stream('Find me the weather in Tokyo.')
```

迁移后：

```typescript
import { Agent } from '@mastra/core/agent'
import { Memory } from '@mastra/memory'

const memory = new Memory()

const agent = new Agent({
  id: 'agent-network',
  name: 'agent-network',
  agents: { agent1, agent2 },
  tools: { tool1, tool2 },
  model: 'openai/gpt-5.6-sol',
  instructions: 'You are a network agent that can help users with a variety of tasks.',
  memory,
})

await agent.network('Find me the weather in Tokyo.')
```

如果你之前使用 `NewAgentNetwork` 原语，可以用 `Agent` 替换 `NewAgentNetwork`。

迁移前：

```typescript
import { NewAgentNetwork } from '@mastra/core/network/vnext'

const agent = new NewAgentNetwork({
  id: 'agent-network',
  name: 'agent-network',
  agents: { agent1, agent2 },
  workflows: { workflow1 },
  tools: { tool1, tool2 },
  model: 'openai/gpt-5.6-sol',
  instructions: 'You are a network agent that can help users with a variety of tasks.',
})

await agent.loop('Find me the weather in Tokyo.')
```

迁移后：

```typescript
import { Agent } from '@mastra/core/agent'
import { Memory } from '@mastra/memory'

const memory = new Memory()

const agent = new Agent({
  id: 'agent-network',
  name: 'agent-network',
  agents: { agent1, agent2 },
  workflows: { workflow1 },
  tools: { tool1, tool2 },
  model: 'openai/gpt-5.6-sol',
  instructions: 'You are a network agent that can help users with a variety of tasks.',
  memory,
})

await agent.network('Find me the weather in Tokyo.')
```
