If you’ve applied for GPT-4 API access and are still waiting for a reply from OpenAI, you’re not alone. Thankfully, there’s a way to get unofficial access via chat.openai.com by leveraging Selenium WebDriver. In this article, you’ll learn how to set up and use this unofficial API efficiently.

Understanding the Unofficial API

This unofficial API package utilizes Selenium to emulate user interactions, allowing you to access the capabilities of GPT-4 (and DALL-E 3) if you have a ChatGPT Plus subscription. However, please keep in mind that this is not an official implementation, and its use may violate OpenAI’s Terms of Service.

Installation Steps

To get started, you’ll need to install the necessary Python package. Just follow these simple steps:

• Open your terminal or command prompt.
• Run the following command:

pip install gpt4-openai-api

Setting Up the API

Here’s a step-by-step guide on how to set up your API access:

1. Retrieve your session token.
2. Use the Python code below to interact with GPT-4:

from gpt4_openai import GPT4OpenAI

# Token is the __Secure-next-auth.session-token from chat.openai.com
llm = GPT4OpenAI(token=my_session_token, headless=False, model="gpt-4")

# Sample interaction
response = llm("If there are 10 books in a room and I read 2, how many books are still in the room?")
print(response)

Explaining the Code: An Analogy

Think of the code snippet you just saw as sending a letter to a knowledge wizard (GPT-4) who resides in a castle (the API). The session token is like a secret password that lets you into the castle. Once inside, you can ask the wizard questions, and he responds with wisdom (answers). However, if you don’t have the correct password (session token), you won’t be granted access!

Working with DALL-E 3 and Browsing

To utilize DALL-E 3 or harness browsing capabilities with the API, you can incorporate the following code snippets:

DALL-E 3 Support

llm = GPT4OpenAI(token=my_session_token, headless=False, model="gpt-4")  
img_bytes = llm.generate_image("Generate an isometric image of a cute doggo inside a house.", image_path="img_save_path.png")

Browsing Support

llm = GPT4OpenAI(token=my_session_token, headless=False, model="gpt-4-browsing")  
response = llm("What is the age difference between Dua Lipa and her boyfriend?")
print(response)

Langchain Support

This library also integrates with Langchain, allowing for seamless functionality within that ecosystem. Here’s an example:

from langchain import LLMChain
from langchain.prompts.chat import (ChatPromptTemplate, SystemMessagePromptTemplate, AIMessagePromptTemplate, HumanMessagePromptTemplate)

template = "You are a helpful assistant that translates English to pirate."
system_message_prompt = SystemMessagePromptTemplate.from_template(template)
human_message_prompt = HumanMessagePromptTemplate.from_template(text)

chat_prompt = ChatPromptTemplate.from_messages([system_message_prompt, example_human, example_ai, human_message_prompt])
llm = GPT4OpenAI(token=my_session_token)
chain = LLMChain(llm=llm, prompt=chat_prompt)
print(chain.run("My name is John and I like to eat pizza."))

Getting Your Session Token

Follow these steps to find your session token:

1. Go to chat.openai.com.
2. Open developer tools by pressing F12.
3. Locate the __Secure-next-auth.session-token under Application > Storage > Cookies.
4. Copy the value from the Cookie Value field.

Troubleshooting

If you encounter any issues while using the unofficial API, here are some troubleshooting tips:

• Ensure your session token is up-to-date. Tokens can expire or change.
• Check browser compatibility with the Selenium version you are using.
• Make sure you comply with OpenAI’s Terms of Service to avoid any misuse.
