CerebriumAI#

Cerebrium is an AWS Sagemaker alternative. It also provides API access to several LLM models.

This notebook goes over how to use Langchain with CerebriumAI.

Install cerebrium#

The cerebrium package is required to use the CerebriumAI API. Install cerebrium using pip3 install cerebrium.

# Install the package
!pip3 install cerebrium

import os
from langchain.llms import CerebriumAI
from langchain import PromptTemplate, LLMChain

Make sure to get your API key from CerebriumAI. See here. You are given a 1 hour free of serverless GPU compute to test different models.

os.environ["CEREBRIUMAI_API_KEY"] = "YOUR_KEY_HERE"

You can specify different parameters such as the model endpoint url, max length, temperature, etc. You must provide an endpoint url.

llm = CerebriumAI(endpoint_url="YOUR ENDPOINT URL HERE")

We will create a prompt template for Question and Answer.

template = """Question: {question}

Answer: Let's think step by step."""

prompt = PromptTemplate(template=template, input_variables=["question"])

llm_chain = LLMChain(prompt=prompt, llm=llm)

Provide a question and run the LLMChain.

question = "What NFL team won the Super Bowl in the year Justin Beiber was born?"

llm_chain.run(question)
