ChatGPT has been named one of the fastest-growing apps in internet history. The popular artificial intelligence (AI) chatbot reached 100 million users two months after launch and its momentum has steadily kept pace. Since its initial launch on November 30, 2022, the language model that powers ChatGPT has consistently matured with each version, with the latest being GPT-4.

What Is GPT-4?

GPT-4 is OpenAI’s newest language model system and the most advanced addition to the GPT (Generative Pre-Trained Transformer) series of language models. It is smarter than the technology used by the original ChatGPT, which is based on GPT-3.5, and has been optimized to learn and understand complex patterns in natural language to provide users with highly sophisticated outputs.

Learning how to use GPT-4 is similar to learning other versions. However, with its unique multimodal model, it is capable of accepting not only words but images too. OpenAI claims that this next-generation language model has surpassed the functionalities of ChatGPT in three distinct areas: visual input, creativity, and longer context. It is also more adept at collaborating with users on creative projects.

How to Use GPT-4: Step-by-Step Guide

The most common way to use GPT-4 is by purchasing a ChatGPT Plus subscription. In addition to unlocking GPT-4, a ChatGPT Plus subscription unlocks a Code Interpreter tool and ChatGPT plugins. To try ChatGPT-4, follow these steps:

1. Navigate to the ChatGPT website at

2. Click on the ‘Sign Up’ button and enter your email address. Alternatively, you can sign in using your existing Microsoft, Google, or Apple account.

4. Under ‘ChatGPT Plus’, click on ‘Upgrade to Plus’.


5. Provide your payment information and pay the $20.00 per month to subscribe.

6. After payment is verified, you’ll receive full access to the latest version of the chatbot.

7. Use GPT-4 to:

  • Generate original content;
  • Research topics;
  • Write or debug code;
  • Create poems, music, or movie scripts;
  • Describe images to blind people;
  • Create a customized cover letter and resume;
  • Explain complex topics;
  • And much more.

When using GPT-4, it’s important to use proper writing prompts to ensure the best answer possible to your query. When learning how to use GPT-4, consider the following tips and tricks:

  • Specify specifics, such as word count and formatting.
  • Ensure that your request is clear and concise.
  • Include relevant keywords in your request to generate more accurate responses.
  • Keep queries simple and straightforward.
  • Train GPT-4 to learn your writing style.
  • Ask ChatGPT-4 to reformulate its response if you’re not satisfied.
  • Review the content for accuracy and edit if necessary.
  • Experiment with different prompts to use the tool to its full potential.
  • Understand the limitations of GPT-4 and realign your expectations.
