Have you heard of GPT-4? It is the latest language model for the OpenAI natural language chatbot and is said to be much better than GPT 3.5, which is available from ChatGPT. But how much better is it and what makes it different?
That’s what we’re here to find out, with a head-to-head comparison of these two exciting but distinctly different language models. Ultimately, we can decide if it is worth paying more to subscribe to ChatGPT Plus or if it is better to use GPT-4 for free.
What are GPT 3.5 and GPT-4?

and GPT-3.5 and GPT-4 are natural language models used by OpenAI’s ChatGPT and other AI chatbots to create human-like interactions. Both can answer queries such as questions or requests and can provide very similar responses to a real person. Both are capable of passing the exams. would confuse most people, including complicated legal exams, and they can write in the style of any writer with publicly available work.
But GPT-4 is the newer of the two models, so it comes with a number of updates and improvements that OpenAI thinks are worth locking up behind a paywall, at least for now.
How can you use GPT 3.5 and GPT-4?
GPT-3.5 is fully available as part of ChatGPT, at Open AI website. You’ll need an account to log in, but it’s completely free and you’ll be able to chat with ChatGPT as much as you want, assuming the servers aren’t too busy. You can also find GPT 3.5 using a number of other chatbots that are widely available on different sites and services.
GPT-4, on the other hand, is a bit harder to come by. You can use it through the OpenAI website as part of your ChatGPT Plus subscription. It costs $20 per month, but you’ll also get priority access to ChatGPT, so you’re never too busy to chat. There are a few ways to use GPT-4 for free, besides using Bing Chat, but these sources tend to have a limited number of questions or don’t always use GPT-4 due to limited availability.
What is the difference between GPT 3.5 and GPT-4?
GPT 3.5 was trained on data that eventually allowed it to take into account 175 billion parameters based on the query it receives. This gave her some impressive language skills and allowed her to answer queries in a very human way. However, GPT-4 relies on much more training data and can ultimately take more than 1 trillion parameters into account when providing your answers. GPT-4 was also trained with human and AI feedback for another six months after GPT-3.5, so it had many more fixes and suggestions for how it could be improved.
GPT 4 is also trained on more recent data. While GPT 3.5 was limited to information prior to June 2021, GPT-4 was trained on data up to September 2021, with some information selected after that date, making it a bit more current in its responses.
All of this gives GPT-4 a much greater ability to produce nuanced responses that are more accurate and less prone to what OpenAI describes as “hallucinations.” This means that you should not so often make up information and say that you do not know the answer to something easier.
It was worth trying.
GPT-4 also includes many new protections that OpenAI has put in place to make it less likely to deliver responses that could be considered harmful or illegal. OpenAI claims that GPT-4 is “82% less likely to respond to requests for illegal content.” There are still ways you can Jailbreak ChatGPT, but it’s much better to avoid them.
OpenAI has also made great strides in improving information synthesis with GPT-4. This makes it better able to understand queries with more factors to consider. You can ask him to approach the issue from multiple angles or to consider multiple sources of information when writing his response. This can also be seen in GPT-4’s creative efforts, where asking him to come up with an original story will create something much more compelling and cohesive. GPT-3.5 has a tendency to lose threads midway or make meaningless suggestions for characters that would be physically or canonically impossible.
The improved GPT-4 context window is another important feature that stands out. You can now retain more information from your conversations, allowing you to further refine responses based on your conversation. This means around 25,000 words of context for GPT-4, while GPT-3.5 is limited to just 3,000 words.
That extra understanding and larger context window still means that GPT-4 isn’t quite as quick in its responses. GPT-3.5 will usually fully respond in a few seconds, while GPT-4 will take a minute or more to generate larger responses.
Programation advance
One of the best features of GPT-3.5 is its ability to write code. However, it was not good at iterating, leaving developers trying to use ChatGPT and other AI tools to save time, often spending more time fixing bugs than if they had written the code themselves. GPT-4, on the other hand, is far superior in your initial understanding of the type of code you want and your ability to improve it.
GPT-4 may get prompts like “improve performance” or “this code is giving me the X error, can you fix it?” GPT-3.5 would not fully understand these queries, but GPT-4 can and will act on them efficiently, allowing you to improve your own answers in future attempts. The ability to give you starting tasks outside of your original target is an impressive improvement on the GPT-4.
understand the images
GPT-3.5 is primarily a text tool, while GPT-4 can understand images. If you give him a photo, he can describe what’s in it, understand the context of what’s there, and make suggestions based on that. This has led some people to use GPT-4 to create recipe ideas based on pictures of their fridges. In other cases, GPT-4 was used to code a web page based on a quick sketch.
Some people have even started combining GPT-4 with other AIs, like Midjourney, to generate entirely new query-based AI art that GPT-4 came up with.
