Difference between GPT v3.5 and v4 in examples: Is it really better?

As an experienced recruiter, I often come across articles discussing the latest advancements in Artificial Intelligence (AI) and how they impact various industries, including Human Resources (HR). One topic that has recently piqued my interest is the comparison between the GPT v3.5 and v4 language models.

GPT, which stands for Generative Pre-trained Transformer, is a series of AI models developed by OpenAI. These models have evolved over time, and GPT v4 is the latest iteration. In this article, we will delve into the differences between GPT v3.5 and v4, using examples to illustrate their capabilities and determine whether the newer version is truly better than its predecessor.

GPT v3.5: A brief overview

GPT v3.5 is an AI language model that gained widespread recognition for its ability to generate human-like text. With billions of parameters, it can understand and produce text in multiple languages, making it a valuable tool for various applications, from chatbots and virtual assistants to content generation and more.

GPT v4: What's new?

GPT v4 builds on the foundation laid by GPT v3.5, with several key improvements:

  1. Increased model size: GPT v4 has more than 175 billion parameters, compared to GPT v3.5's 13 billion. This increase in model size allows GPT v4 to better understand and generate text.

  2. Improved text generation capabilities: GPT v4 has been fine-tuned to generate longer, more coherent, and contextually relevant pieces of text.

  3. Enhanced performance across multiple languages: GPT v4 has been trained on a more diverse range of languages, making it better equipped to understand and generate text in various languages.

  4. More focused and accurate answers: GPT v4 is designed to provide more precise responses to user queries, thanks to its improved understanding of context and ability to infer meaning from surrounding text.

Now, let's look at some examples to better understand the differences between GPT v3.5 and v4.

Example 1: Writing an article

Suppose we ask both models to write an article on the topic: "The role of AI in HR processes."

GPT v3.5 output:

The role of AI in HR processes is becoming increasingly important. With the advent of AI-powered tools, recruiters can now automate many tasks, such as screening resumes and scheduling interviews. This not only saves time but also helps eliminate human bias in the hiring process.

GPT v4 output:

The role of AI in HR processes has transformed significantly in recent years, revolutionizing how organizations manage their talent acquisition and development. With the integration of advanced AI-powered tools, HR professionals can streamline tasks like resume screening, interview scheduling, and even predicting employee performance. These advancements have led to improved efficiency, reduced bias, and ultimately, better decision-making in the hiring process.

In this example, GPT v4's output is more detailed, coherent, and contextually relevant compared to GPT v3.5.

Example 2: Answering a question

Let's consider a question: "What are the key differences between GPT v3.5 and v4?"

GPT v3.5 output:

The key differences between GPT v3.5 and v4 include the size of the models, with v4 having more parameters, and improved text generation capabilities.

GPT v4 output:

The key differences between GPT v3.5 and v4 are:

  1. Model size: GPT v4 has a significantly larger number of parameters (over 175 billion) compared to GPT v3.5 (13 billion).
  2. Text generation capabilities: GPT v4 has been fine-tuned to generate longer, more coherent, and contextually relevant text.
  3. Multilingual performance: GPT v4 has improved performance across multiple languages due to its diverse language training data.
  4. Answer accuracy: GPT v4 provides more focused and accurate answers to user queries, thanks to its enhanced contextual understanding.

In this example, GPT v4 offers a more comprehensive and structured answer compared to GPT v3.5.

Adding scientific facts

An interesting scientific fact related to language models like GPT is the concept of the "scaling law." Researchers have found that as the size of these models increases (i.e., more parameters), their performance on various natural language processing tasks improves. This phenomenon is one of the driving forces behind the development of larger models like GPT v4.


In conclusion, GPT v4 outperforms GPT v3.5 in several key areas, including model size, text generation capabilities, multilingual performance, and answer accuracy. With its enhanced capabilities, GPT v4 has the potential to revolutionize a wide range of industries, including HR, by offering improved tools for content generation, virtual assistance, and more. However, it is essential to remember that AI language models, like any technology, should be used responsibly and ethically to ensure their benefits are maximized while minimizing potential harm.
