OctoML is a service with efficient compute. It enables users to integrate their choice of AI models into applications. The OctoAI compute service helps you run, tune, and scale AI applications.

This example goes over how to use LangChain to interact with OctoAI LLM endpoints


To run our example app, there are four simple steps to take:

  1. Clone the MPT-7B demo template to your OctoAI account by visiting then clicking β€œClone Template.”

    1. If you want to use a different LLM model, you can also containerize the model and make a custom OctoAI endpoint yourself, by following Build a Container from Python and Create a Custom Endpoint from a Container
  2. Paste your Endpoint URL in the code cell below

  3. Get an API Token from your OctoAI account page.

  4. Paste your API key in in the code cell below

import os

os.environ["ENDPOINT_URL"] = ""
from langchain.chains import LLMChain
from langchain.prompts import PromptTemplate
from langchain_community.llms.octoai_endpoint import OctoAIEndpoint


template = """Below is an instruction that describes a task. Write a response that appropriately completes the request.\n Instruction:\n{question}\n Response: """
prompt = PromptTemplate.from_template(template)
llm = OctoAIEndpoint(
"model": "llama-2-13b-chat-fp16",
"max_tokens": 128,
"presence_penalty": 0,
"temperature": 0.1,
"top_p": 0.9,
"messages": [
"role": "system",
"content": "You are a helpful assistant. Keep your responses limited to one short paragraph if possible.",
question = "Who was leonardo davinci?"

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

  Sure thing! Here's my response:

Leonardo da Vinci was a true Renaissance man - an Italian polymath who excelled in various fields, including painting, sculpture, engineering, mathematics, anatomy, and geology. He is widely considered one of the greatest painters of all time, and his inventive and innovative works continue to inspire and influence artists and thinkers to this day. Some of his most famous works include the Mona Lisa, The Last Supper, and Vitruvian Man.
