模型功能

请参阅下表标题中的链接,了解如何使用特定功能的指南。

设置

要访问 ChatGroq 模型,您需要创建一个 Groq 账户、获取 API 密钥,并安装 @langchain/groq 集成包。

凭证

要使用 Groq API,您需要一个 API 密钥。注册 Groq 账户并创建 API 密钥。 然后,您可以在终端中将 API 密钥设置为环境变量:
export GROQ_API_KEY="your-api-key"
如果您想自动跟踪模型调用,还可以通过取消注释以下内容来设置您的 LangSmith API 密钥:
# export LANGSMITH_TRACING="true"
# export LANGSMITH_API_KEY="your-api-key"

安装

LangChain ChatGroq 集成位于 @langchain/groq 包中:
npm install @langchain/groq @langchain/core

实例化

现在我们可以实例化我们的模型对象并生成聊天补全:
import { ChatGroq } from "@langchain/groq"

const llm = new ChatGroq({
    model: "llama-3.3-70b-versatile",
    temperature: 0,
    maxTokens: undefined,
    maxRetries: 2,
    // other params...
})

调用

const aiMsg = await llm.invoke([
    {
      role: "system",
      content: "You are a helpful assistant that translates English to French. Translate the user sentence.",
    },
    { role: "user", content: "I love programming." },
])
aiMsg
AIMessage {
  "content": "I enjoy programming. (The French translation is: \"J'aime programmer.\")\n\nNote: I chose to translate \"I love programming\" as \"J'aime programmer\" instead of \"Je suis amoureux de programmer\" because the latter has a romantic connotation that is not present in the original English sentence.",
  "additional_kwargs": {},
  "response_metadata": {
    "tokenUsage": {
      "completionTokens": 73,
      "promptTokens": 31,
      "totalTokens": 104
    },
    "finish_reason": "stop"
  },
  "tool_calls": [],
  "invalid_tool_calls": []
}
console.log(aiMsg.content)
I enjoy programming. (The French translation is: "J'aime programmer.")

Note: I chose to translate "I love programming" as "J'aime programmer" instead of "Je suis amoureux de programmer" because the latter has a romantic connotation that is not present in the original English sentence.

Json 调用

const messages = [
  {
    role: "system",
    content: "You are a math tutor that handles math exercises and makes output in json in format { result: number }.",
  },
  { role: "user",  content: "2 + 2 * 2" },
];

const aiInvokeMsg = await llm.invoke(messages, { response_format: { type: "json_object" } });

// if you want not to pass response_format in every invoke, you can bind it to the instance
const llmWithResponseFormat = llm.bind({ response_format: { type: "json_object" } });
const aiBindMsg = await llmWithResponseFormat.invoke(messages);

// they are the same
console.log({ aiInvokeMsgContent: aiInvokeMsg.content, aiBindMsg: aiBindMsg.content });
{
  aiInvokeMsgContent: '{\n"result": 6\n}',
  aiBindMsg: '{\n"result": 6\n}'
}
