AutoGPT

info

AutoGPT是一个使用长期记忆和专为独立工作设计的提示（即无需要求用户输入)的自定义代理来执行任务。

同构示例

在这个例子中，我们使用AutoGPT为给定位置预测天气。 这个例子被设计为运行在所有的JS环境中，包括浏览器。

Node.js示例

在这个示例中，我们使用AutoGPT为给定位置预测天气。 这个示例被设计为在Node.js中运行，因此它使用本地文件系统和一个仅限Node的向量存储。

This example is designed to run in Node.js， and uses the local filesystem and a Node-only vector store.

const tools = [
  new ReadFileTool({ store }),
  new WriteFileTool({ store }),
  new SerpAPI(process.env.SERPAPI_API_KEY, {
    location: "San Francisco,California,United States",
    hl: "en",
    gl: "us",
  }),
];

const vectorStore = new HNSWLib(new OpenAIEmbeddings(), {
  space: "cosine",
  numDimensions: 1536,
});
