在智能体中使用
首先，确保你已经安装了 LangGraph：
@langchain/langgraph
然后，实例化你的大语言模型（LLM）以在 React 智能体中使用：
import { ChatWatsonx } from "@langchain/community/chat_models/ibm";
const llm = new ChatWatsonx({
version: "2024-05-31",
serviceUrl: process.env.WATSONX_AI_SERVICE_URL,
model: "ibm/granite-3-8b-instruct",
projectId: process.env.WATSONX_AI_PROJECT_ID,
});
import { createReactAgent } from "@langchain/langgraph/prebuilt";
const agent = createReactAgent({ llm, tools });
const exampleQuery = "Who won F1 championship in 2022?";
const events = await agent.stream(
{ messages: [{ role: "user", content: exampleQuery }] },
{ streamMode: "values" }
);
for await (const event of events) {
const lastMsg = event.messages[event.messages.length - 1];
if (lastMsg.tool_calls?.length) {
console.dir(lastMsg.tool_calls, { depth: null });
} else if (lastMsg.content) {
console.log(lastMsg.content);
}
}
Who won F1 championship in 2022?
