Open AI amused the world with the invention of ChatGPT in November 2022. Recently, it has rolled out GPT-4, ChatGPT’s advanced version, with more exciting features. This model promises better performance than the previous GPT-3.5 model.

Several ChatGPT users are already exploring the new model and sharing their thoughts online. If you are curious about what GPT-4 offers, read this post. This comprehensive guide covers various GPT-4 related topics, including how to access it, its features, and much more.

What is GPT-4?

What is GPT-4?

GPT-4 (Generative Pre-Trained Transformer) is Open AI’s latest large multimodal model. This model is trained with extensive knowledge and can handle text and images as inputs. However, it can only generate textual outputs.

ChatGPT-4 was released on 14 March 2023 worldwide, but it is not available to free users. It is only accessible via ChatGPT Plus, which costs $20 monthly. Open AI has also released the ChatGPT-4 API for developers, accessible by joining its waitlist.

How does GPT-4 work?

Open AI hasn’t provided much technical information regarding ChatGPT-4’s working. The company says GPT-4 is trained using supervised learning and reinforcement learning methods with human and AI feedback.

It hasn’t even revealed the number of parameters on which GPT-4 is trained. So, the exact data regarding its working process is not available.

Nevertheless, it is known that GPT-4 is trained with more than 300 billion words. It uses this knowledge to respond to its users. It was trained using probability to predict the relevant answer to any question. Using this technique, the model constantly improves to produce better responses in a natural language or conversational tone.

GPT-4 is not accessible as a separate website or application. It is integrated into other websites that use this technology to respond to users. You can access GPT-4 via platforms like Microsoft Bing, ChatGPT, Duolingo, Khan Academy, etc.

This section will discuss the process of accessing GPT-4 via ChatGPT Plus. Remember, you must be a Plus member to access GPT-4 on ChatGPT. Below are the steps to use GPT-4 with ChatGPT:

The Features of Chat GPT-4

Chat GPT-4 will come with various new functionalities. Though it’s not an entirely new model, it does feature a few new functionalities that make it better than GPT-3.5. Here are some features of Chat GPT-4:

Larger model size

GPT-4 is anticipated to launch with a new product, Foundry. This product will comprise two Davinci (DV) models with a higher capacity for taking text input.

One will accept up to four times more (8K), and the other will accept up to sixteen times more (32K) text. The larger model size will allow it to solve complex problems faster.

Improved language generation

GPT-3.5 used billions of parameters for text generation. However, GPT-4 will use 100 trillion parameters for language generation. This indicates that GPT-4 will be much closer to the human brain, helping it to generate faster and more accurate responses.

Multimodal learning

Open AI hinted in a recent interview that its new GPT-4 model would have multimodal functionalities. It will support images and videos as input. This news was confirmed by Microsoft’s CTO, who hinted that GPT-4 would be added to Bing. Its multimodal capabilities will help the search engine respond to user queries much more efficiently.

Few-shot learning

Open AI’s GPT-4 will use the few-shot learning method. This method will feed a small amount of data into the machine to guide its predictions. It will then move onto a large dataset. This method helps GPT-4 to produce more accurate responses.

Better optimization

Training large models is a tedious task. It requires a lot of time and money. However, GPT-4 is trained to give optimized results using trillions of parameters. Researchers have been able to train this model at a much lesser cost than that required to train large models.

How does GPT-4 differ from ChatGPT?

GPT-4 and ChatGPT are Open AI products that use AI to respond to user queries. However, there is a significant difference between these two products. ChatGPT is an online interface/ platform that interacts with its users.

It is the end product accessible by the users directly. The users won’t be concerned about its technology, working, or training data set.

Contrarily, GPT-4 itself is a technology incorporated within ChatGPT and similar platforms. It isn’t a separate application or website. To use GPT-4, you need access to websites offering GPT-4. You can then get relevant responses from GPT-4.

Some platforms offering GPT-4 include Duolingo, Be My Eyes, Microsoft Bing, Stripe, Khan Academy, etc.

GPT-4 VS GPT-3.5: what’s the difference?

GPT-4 is Open AI’s multimodal model. Unlike the previous GPT models, this model accepts images and texts as inputs and produces relevant textual output. Further, the model is designed to outperform earlier models in several ways.

Some factors that distinguish GPT-4 from GPT-3.5 include:

  • GPT-4 is more aligned than GPT-3.5. It is less likely to respond to disallowed content or produce irrelevant and offensive responses.
  • GPT-4 can produce more than 40% correct factual data compared to GPT-3.5.
  • The model can clear aptitude exams with a far better score than GPT-3.5.
  • GPT-4 is trained on a substantially large dataset compared to GPT-3.5. However, Open AI refuses to declare the GPT-4 model size.
  • The model is capable of understanding complex tasks and generating longer text outputs. It can remember 16 times more responses compared to the previous models.

What are the capabilities of GPT-4?

GPT-4 is designed to be more creative and reliable and handle more nuanced instructions. It is fine-tuned to offer more accurate and relevant responses. Some of the significant abilities of this platform are as follows:

  • GPT-4 can handle images and texts as inputs. This enables the platform to analyze and summarize pictures in text format, answer questions containing diagrams, and describe humor in photographs.
  • It can identify or modify the tone and style of the given content using the System message directive.
  • GPT-4 can refer to scientific papers and research journals to provide detailed answers to all queries. It can also process complicated questions much faster than GPT-3.5.
  • GPT-4 can answer several exams with a score equivalent to that of the top 10% toppers. For example, it can answer BAR, SAT, GRE, and medical exams.

What are the limitations of GPT-4?

GPT-4 is a much more advanced version of GPT-3.5. However, it comes with some limitations. Open AI has also accepted the fact that its model is not error-free. Some of the limitations you may notice while using GPT-4 include the following:

  • GPT-4 may hallucinate facts and make reasoning errors.
  • It isn’t a completely reliable model.
  • The results produced in other languages are not as good as in English.
  • The model produces several errors while solving mathematical problems.
