Setup​

To access ChatGroq models you’ll need to create a Groq account, get an API key, and install the @langchain/groq integration package.

Credentials​

In order to use the Groq API you’ll need an API key. You can sign up for a Groq account and create an API key here. Then, you can set the API key as an environment variable in your terminal:

export GROQ_API_KEY="your-api-key"

If you want to get automated tracing of your model calls you can also set your LangSmith API key by uncommenting below:

# export LANGCHAIN_TRACING_V2="true"
# export LANGCHAIN_API_KEY="your-api-key"

Installation​

The LangChain ChatGroq integration lives in the @langchain/groq package:

yarn add @langchain/groq

Instantiation​

Now we can instantiate our model object and generate chat completions:

import { ChatGroq } from "@langchain/groq";

const llm = new ChatGroq({
model: "mixtral-8x7b-32768",
temperature: 0,
maxTokens: undefined,
maxRetries: 2,
// other params...
});

Invocation​

const aiMsg = await llm.invoke([
[
"system",
"You are a helpful assistant that translates English to French. Translate the user sentence.",
],
["human", "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.

Chaining​

We can chain our model with a prompt template like so:

import { ChatPromptTemplate } from "@langchain/core/prompts";

const prompt = ChatPromptTemplate.fromMessages([
[
"system",
"You are a helpful assistant that translates {input_language} to {output_language}.",
],
["human", "{input}"],
]);

const chain = prompt.pipe(llm);
await chain.invoke({
input_language: "English",
output_language: "German",
input: "I love programming.",
});
AIMessage {
"content": "That's great! I can help you translate English phrases related to programming into German.\n\n\"I love programming\" can be translated to German as \"Ich liebe Programmieren\".\n\nHere are some more programming-related phrases translated into German:\n\n* \"Programming language\" = \"Programmiersprache\"\n* \"Code\" = \"Code\"\n* \"Variable\" = \"Variable\"\n* \"Function\" = \"Funktion\"\n* \"Array\" = \"Array\"\n* \"Object-oriented programming\" = \"Objektorientierte Programmierung\"\n* \"Algorithm\" = \"Algorithmus\"\n* \"Data structure\" = \"Datenstruktur\"\n* \"Debugging\" = \"Debuggen\"\n* \"Compile\" = \"Kompilieren\"\n* \"Link\" = \"VerknΓΌpfen\"\n* \"Run\" = \"AusfΓΌhren\"\n* \"Test\" = \"Testen\"\n* \"Deploy\" = \"Bereitstellen\"\n* \"Version control\" = \"Versionskontrolle\"\n* \"Open source\" = \"Open Source\"\n* \"Software development\" = \"Softwareentwicklung\"\n* \"Agile methodology\" = \"Agile Methodik\"\n* \"DevOps\" = \"DevOps\"\n* \"Cloud computing\" = \"Cloud Computing\"\n\nI hope this helps! Let me know if you have any other questions or if you need further translations.",
"additional_kwargs": {},
"response_metadata": {
"tokenUsage": {
"completionTokens": 327,
"promptTokens": 25,
"totalTokens": 352
},
"finish_reason": "stop"
},
"tool_calls": [],
"invalid_tool_calls": []
}
