Difference between GPT-3.5 and GPT-4 in ChatGPT

has become one of the most popular artificial intelligence (AI) in the world. To support its users, ChatGPT has released its newest AI language, namely GPT-4, in March 2023.

Previously, ChatGPT used an AI language called GPT-3.5 which could be accessed for free. However,  who want to use GPT-4 must subscribe first.

So, what is the difference between GPT-3.5 and GPT-4? Is it true that the newest AI language from ChatGPT is more feature-rich and powerful? Check out the explanation in this article.

Difference between GPT-3.5 and GPT-4

Even though both are language model programs in conversation or dialogue format, it turns out there are differences between GPT-3.5 and GPT-4. Quoting the Coursera page, here are a number of differences:

1. Can use images

In GPT-3.5, users had to write prompts using text to generate AI output from ChatGPT. Meanwhile, in the GPT-4 version, you can use text and images.

So, you can enter commands in the form of text and images. After that, GPT-4 will provide an explanation or answer to the text or image you sent as a prompt.

For example, you include a picture of the inside of the refrigerator and its contents. Later, AI will suggest what food or drink recipes can be made with the ingredients in the image.

2. Produce safer and more accurate answers

OpenAI claims that GPT-4 is more secure in generating answers written to prompts than the GPT-3.5 version.

"82 percent less likely to respond to requests for unauthorized content and 40 percent more likely to produce factual responses compared to GPT-3.5 in our internal evaluation," wrote OpenAI on its official website.

The features contained in GPT-4 are certainly good news. Because, in several cases there is often misinformation, inaccuracy and bias in the answers produced.

3. Have a bigger memory

GPT-4 is claimed to be able to remember more conversations with its users than GPT-3.5. Previously, GPT-3.5 had limitations in conveying information that was only available before 2021 and had a limited short-term memory, namely around 8,000 words.

For comparison, GPT-4 is claimed to have eight times more memory than the GPT-3.5 version, which can store 64,000 words. Then, GPT-4 also has a longer context window or amount of text that can be processed simultaneously.

In fact, the GPT-4 Turbo version can process up to 128,000 words. This feature can help users perform various tasks, such as including a website link in the prompt and asking ChatGPT to consider the source.

4. Wider General Knowledge

The general knowledge base in GPT-4 is said to be better than GPT-3.5. It allows users to generate, edit, and repeat various tasks such as composing songs, writing screenplays, or learning the user's writing style.

In addition, GPT-4 has used the latest data up to April-December 2023, so it can provide better and more appropriate answers. However, it all depends on the model version too.

5. Price

The final difference is in terms of price. Currently, GPT-3.5 is available in a free version and can be accessed by anyone. Even so, the features feel incomplete and not up to date.

Meanwhile, GPT-4 can be accessed by subscribing every month. If are interested, you have to spend US$ 20 or around Rp. 320 thousand per month.

ChatGPT also provides a 'Team' plan targeted at workers or students who need more features. Each person will be charged US$ 25 or the equivalent of Rp. 400 thousand per month.

That's the difference between GPT-3.5 and GPT-4 in ChatGPT. Hopefully this article can help you.
