Install the langchain-groq package if not already installed:

pip install langchain-groq

Request an API key and set it as an environment variable:


Alternatively, you may configure the API key when you initialize ChatGroq.

Import the ChatGroq class and initialize it with a model:

from langchain_core.prompts import ChatPromptTemplate
from langchain_groq import ChatGroq
chat = ChatGroq(temperature=0, model_name="mixtral-8x7b-32768")

You can view the available models here.

If you do not want to set your API key in the environment, you can pass it directly to the client:

chat = ChatGroq(temperature=0, groq_api_key="YOUR_API_KEY", model_name="mixtral-8x7b-32768")

Write a prompt and invoke ChatGroq to create completions:

system = "You are a helpful assistant."
human = "{text}"
prompt = ChatPromptTemplate.from_messages([("system", system), ("human", human)])

chain = prompt | chat
chain.invoke({"text": "Explain the importance of low latency LLMs."})
AIMessage(content='Low Latency Large Language Models (LLMs) are a type of artificial intelligence model that can understand and generate human-like text. The term "low latency" refers to the model\'s ability to process and respond to inputs quickly, with minimal delay.\n\nThe importance of low latency in LLMs can be explained through the following points:\n\n1. Improved user experience: In real-time applications such as chatbots, virtual assistants, and interactive games, users expect quick and responsive interactions. Low latency LLMs can provide instant feedback and responses, creating a more seamless and engaging user experience.\n\n2. Better decision-making: In time-sensitive scenarios, such as financial trading or autonomous vehicles, low latency LLMs can quickly process and analyze vast amounts of data, enabling faster and more informed decision-making.\n\n3. Enhanced accessibility: For individuals with disabilities, low latency LLMs can help create more responsive and inclusive interfaces, such as voice-controlled assistants or real-time captioning systems.\n\n4. Competitive advantage: In industries where real-time data analysis and decision-making are crucial, low latency LLMs can provide a competitive edge by enabling businesses to react more quickly to market changes, customer needs, or emerging opportunities.\n\n5. Scalability: Low latency LLMs can efficiently handle a higher volume of requests and interactions, making them more suitable for large-scale applications and services.\n\nIn summary, low latency is an essential aspect of LLMs, as it significantly impacts user experience, decision-making, accessibility, competitiveness, and scalability. By minimizing delays and response times, low latency LLMs can unlock new possibilities and applications for artificial intelligence in various industries and scenarios.')

ChatGroq also supports async and streaming functionality:

chat = ChatGroq(temperature=0, model_name="mixtral-8x7b-32768")
prompt = ChatPromptTemplate.from_messages([("human", "Write a Limerick about {topic}")])
chain = prompt | chat
await chain.ainvoke({"topic": "The Sun"})
AIMessage(content="There's a star that shines up in the sky,\nThe Sun, that makes the day bright and spry.\nIt rises and sets,\nIn a daily, predictable bet,\nGiving life to the world, oh my!")
chat = ChatGroq(temperature=0, model_name="llama2-70b-4096")
prompt = ChatPromptTemplate.from_messages([("human", "Write a haiku about {topic}")])
chain = prompt | chat
for chunk in{"topic": "The Moon"}):
print(chunk.content, end="", flush=True)
The moon's gentle glow
Illuminates the night sky
Peaceful and serene
