Firmware

Mastra のモデルルーターを通じて 26 個の Firmware モデルを利用できます。認証には FIRMWARE_API_KEY 環境変数が自動的に使用されます。

詳しくは、Firmware のドキュメントを参照してください。

.env

FIRMWARE_API_KEY=your-api-key

src/mastra/agents/my-agent.ts

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

const agent = new Agent({
  id: "my-agent",
  name: "My Agent",
  instructions: "You are a helpful assistant",
  model: "firmware/claude-haiku-4-5"
});

// Generate a response
const response = await agent.generate("Hello!");

// Stream a response
const stream = await agent.stream("Tell me a story");
for await (const chunk of stream) {
  console.log(chunk);
}
