How to Upgrade to GPT-4

To enhance your ChatGPT experience by subscribing to ChatGPT Plus, follow these steps:

  1. Access Your OpenAI Account: Visit the ChatGPT login page. Here, you can either sign in to your existing account or create a new one. For a new account, you have the option to use your email, Google, or Microsoft account. If you're a new user, select 'Sign up'; if you already have an account, simply log in with your OpenAI credentials.

  2. Initiate the Upgrade Process: Once logged in, you'll land on the main chatbot page. Instead of starting a chat, look for the "Upgrade to Plus" option on the right-hand side of the page and click on it to proceed.

  3. Confirm Your Upgrade Choice: After clicking "Upgrade to Plus", a popup will appear for confirmation. It will display the differences in features and pricing between the free and Plus plans. If you decide to proceed, click on the green "Upgrade plan" button.

  4. Finalize Your Purchase: You'll be directed to a checkout page to complete your purchase. This step involves providing standard online purchase details such as your email, payment information, and billing address.

Currently, ChatGPT-4 is priced at $20/mo


ChatGPT-4 vs GPT-3.5

  1. Enhanced Multimodal Capabilities: GPT-4 surpasses GPT-3.5 with its multimodal abilities, handling text, images, and voice. It can analyze images, generate images, and interact through voice. For example, it can suggest recipes based on an image of refrigerator contents. ChatGPT Plus users can upload documents for analysis. GPT-4 can generate images using DALL-E 3 and incorporates Whisper for voice recognition and response in the mobile app.

  2. Improved Nuance and Accuracy: GPT-4 is described as 10 times more advanced than GPT-3.5, offering more nuanced and accurate responses due to its larger size and longer memory. While GPT-3.5 has a short-term memory of about 8,000 words, GPT-4 extends to 64,000 words, soon to be 128,000. GPT-4's training involves around 100 trillion parameters, significantly more than GPT-3's 175 billion.

  3. Access to Up-to-date Information: ChatGPT Plus, unlike the free version, can access the internet through the 'Browse with Bing' feature, allowing it to provide current information. For instance, it can identify the latest iPhone model accurately, unlike GPT-3.5 or the free ChatGPT.

  4. Plugin Use and Integration: Access to ChatGPT plugins is exclusive to Plus subscribers using GPT-4. These plugins, developed by OpenAI and third parties, enhance ChatGPT-4's capabilities, such as finding flights or extracting information from PDF documents.

Differences Presented in a Table:

Feature/Aspect GPT-4 GPT-3.5
Multimodal Capabilities Can analyze text, images, voice; generate images; voice interaction Limited to text
Document Analysis Available for ChatGPT Plus users Not available
Image Generation Uses DALL-E 3 for image creation Not capable
Voice Interaction Incorporates Whisper for voice recognition and response Not capable
Nuance and Accuracy 10 times more advanced; better context understanding Less nuanced and accurate
Model Size and Memory Larger model; short-term memory of 64,000 words (expanding to 128,000) Smaller model; short-term memory of 8,000 words
Training Parameters Around 100 trillion parameters 175 billion parameters
Internet Access ChatGPT Plus can access the internet for current information Cannot access the internet
Plugin Access Exclusive to Plus subscribers; includes various external APIs No access to plugins
Example Plugins Travel plugins, Ask Your PDF plugin Not applicable

Using ChatGPT-4 Best Practices

This guide outlines effective strategies and tactics to enhance the performance of large language models like GPT-4. In short, this is often referred to as prompt engineering. It encourages users to experiment with various methods to discover what works best for their specific needs. Some techniques are particularly effective with advanced models like GPT-4.

Key Strategies for Improved Results:

  1. Provide Clear Instructions: The model performs better when it clearly understands your requirements. Be specific about the type of response you need, whether it's a brief reply, expert-level content, or a particular format. The more precise your instructions, the less the model has to interpret your intent.


    • Detail your query for more relevant answers.

    • Request the model to assume a specific persona.

    • Use delimiters for clarity in complex inputs.

    • Outline the steps for task completion.

    • Give examples and specify output length.

    • Provide reference texts.

  2. Use Reference Texts to Reduce Fabrications: Language models can unintentionally generate incorrect information, especially on obscure topics. Providing reference texts can guide the model to more accurate and reliable answers.


    • Direct the model to use specific reference texts.

    • Request citations from these texts.

  3. Break Down Complex Tasks: Simplify complex tasks into smaller, manageable subtasks. This approach, akin to modular software engineering, reduces error rates and improves task management.


    • Employ intent classification for relevant instructions.

    • Summarize or filter long dialogues.

    • Decompose and summarize lengthy documents step by step.

  4. Allow Time for Thoughtful Processing: Just as humans need time to solve complex problems, models benefit from not being rushed. Encouraging a model to "think" through a problem can lead to more accurate results.


    • Ask the model to explain its reasoning process.

    • Use a sequence of queries to guide its thought process.

    • Check for missed elements in previous responses.

  5. Leverage External Tools: Enhance the model's capabilities by integrating it with other tools. This can include text retrieval systems for information access or code execution engines for mathematical calculations.


    • Implement knowledge retrieval through embeddings-based search.

    • Perform precise calculations or API calls using code execution.

    • Provide access to specific functional tools.

  6. Systematically Test Changes: To ensure that modifications lead to overall performance improvements, systematically evaluate them against a comprehensive set of examples or a test suite.


    • Compare model outputs with gold-standard answers for accuracy.

By applying these strategies and tactics, users can significantly improve the effectiveness and accuracy of their interactions with advanced language models like GPT-4. Those are particularly good to know for UX designers using AI.

To summarise

In conclusion, mastering ChatGPT-4 is about understanding its capabilities, knowing how to effectively communicate your needs, and utilizing the right strategies to get the best results.

By following the steps outlined in this guide to upgrade to ChatGPT Plus, understanding the differences between GPT-4 and its predecessors, and applying best practices for improved interactions, you're well on your way to unlocking the full potential of this advanced AI model.

Remember, the key to success with ChatGPT-4 lies in clear communication, strategic task breakdown, and leveraging external tools when necessary. Happy exploring, and enjoy the journey into the future of AI-powered communication!
