All functionality related to OpenAI

OpenAI is American artificial intelligence (AI) research laboratory consisting of the non-profit OpenAI Incorporated and its for-profit subsidiary corporation OpenAI Limited Partnership. OpenAI conducts AI research with the declared intention of promoting and developing a friendly AI. OpenAI systems run on an Azure-based supercomputing platform from Microsoft.

The OpenAI API is powered by a diverse set of models with different capabilities and price points.

ChatGPT is the Artificial Intelligence (AI) chatbot developed by OpenAI.

Installation and Setup​

  • Install the Python SDK with
pip install openai
  • Get an OpenAI api key and set it as an environment variable (OPENAI_API_KEY)
  • If you want to use OpenAI's tokenizer (only available for Python 3.9+), install it
pip install tiktoken

LLM​

See a usage example.

from langchain_openai import OpenAI

If you are using a model hosted on Azure, you should use different wrapper for that:

from langchain_openai import AzureOpenAI

For a more detailed walkthrough of the Azure wrapper, see here

Chat model​

See a usage example.

from langchain_openai import ChatOpenAI

If you are using a model hosted on Azure, you should use different wrapper for that:

from langchain_openai import AzureChatOpenAI

For a more detailed walkthrough of the Azure wrapper, see here

Text Embedding Model​

See a usage example

from langchain_openai import OpenAIEmbeddings

Tokenizer​

There are several places you can use the tiktoken tokenizer. By default, it is used to count tokens for OpenAI LLMs.

You can also use it to count tokens when splitting documents with 

from langchain.text_splitter import CharacterTextSplitter
CharacterTextSplitter.from_tiktoken_encoder(...)

For a more detailed walkthrough of this, see this notebook

Document Loader​

See a usage example.

from langchain_community.document_loaders.chatgpt import ChatGPTLoader

Retriever​

See a usage example.

from langchain.retrievers import ChatGPTPluginRetriever

Chain​

See a usage example.

from langchain.chains import OpenAIModerationChain

Adapter​

See a usage example.

from langchain.adapters import openai as lc_openai

Tools​

Dall-E Image Generator​

OpenAI Dall-E are text-to-image models developed by OpenAI using deep learning methodologies to generate digital images from natural language descriptions, called "prompts".
