Migration: AgentNetwork to .network() | Migration Guide

Overview​

As of v0.20.0 for @mastra/core, the following changes apply.

Upgrade from AI SDK v4 to v5​

  • Bump all your model provider packages by a major version.

This will ensure that they are all v5 models now.

Memory is required​

  • Memory is now required for the agent network to function properly.

You must configure memory for the agent.

Migration paths​

If you were using the AgentNetwork primitive, you can replace the AgentNetwork with Agent.

Before:

import { AgentNetwork } from "@mastra/core/network";

const agent = new AgentNetwork({
  name: "agent-network",
  agents: [agent1, agent2],
  tools: { tool1, tool2 },
  model: openai("gpt-4o"),
  instructions:
    "You are a network agent that can help users with a variety of tasks.",
});

await agent.stream("Find me the weather in Tokyo.");

After:

import { Agent } from "@mastra/core/agent";
import { Memory } from "@mastra/memory";

const memory = new Memory();

const agent = new Agent({
  name: "agent-network",
  agents: { agent1, agent2 },
  tools: { tool1, tool2 },
  model: openai("gpt-4o"),
  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.");

If you were using the NewAgentNetwork primitive, you can replace the NewAgentNetwork with Agent.

Before:

import { NewAgentNetwork } from "@mastra/core/network/vnext";

const agent = new NewAgentNetwork({
  name: "agent-network",
  agents: { agent1, agent2 },
  workflows: { workflow1 },
  tools: { tool1, tool2 },
  model: openai("gpt-4o"),
  instructions:
    "You are a network agent that can help users with a variety of tasks.",
});

await agent.loop("Find me the weather in Tokyo.");

After:

import { Agent } from "@mastra/core/agent";
import { Memory } from "@mastra/memory";

const memory = new Memory();

const agent = new Agent({
  name: "agent-network",
  agents: { agent1, agent2 },
  workflows: { workflow1 },
  tools: { tool1, tool2 },
  model: openai("gpt-4o"),
  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.");
