Key differences between ChatGPT 3.5 and ChatGPT 4: Detailed comparison

Architecture and model size

ChatGPT 4 is not only smarter when it comes to language, it’s also more flexible thanks to its ability to interact with different types of data.

More power

ChatGPT 4 eclipses ChatGPT 3.5 thanks to a greater number of parameters. In other words,it understands the language better and can generate text more naturally. This makes conversation with the model more fluid and intuitive.

A more versatile architecture

In contrast to ChatGPT 3.5, which can only interact with text, ChatGPT 4 is “multimodal”. This means that‘it can understand and interact with different types of data, not just text.

In particular, it’s now possible to send files or create images with DallE 3 directly from the chat interface. This makes ChatGPT 4 much more versatile and useful in a variety of situations.

Text comprehension and generation skills

ChatGPT 4 is not only more accurate and engaging in its responses, but it’s also better at following longer conversations.

Language comprehension

ChatGPT 4 makes fewer errors and handles long conversations better. As a result, it’s more reliable and better understands the context of what you’re saying.

Text generation

ChatGPT 4 responses are more natural and interesting, making conversation more human and engaging.

Memory management

ChatGPT 4 has better memory than version 3.5. This means you can have longer conversations without the model losing the thread.

Cost comparison of ChatGPT 3.5 and ChatGPT 4

The transition from ChatGPT 3.5 to ChatGPT 4 brings not only technological improvements, but also a change in cost structures.

Here’s a comparison of the costs associated with each of these versions.

Subscription cost

  • ChatGPT 3.5: Free to use, but cost of tokens reduced by 25%. Rate €0.0013 for 1000 input tokens and €0.0017 for 1000 output tokens. More powerful version at 0.0026€ for 1000 input tokens and 0.0034€ for 1000 output tokens.
  • ChatGPT 4: Available via a subscription to ChatGPT Plus for €17 per month. No price change planned at this time.

Cost per use

  • Cost comparison: ChatGPT 4 can be between 20 and 120 times more expensive than ChatGPT 3.5. For example, a question like “Explain the basics of quantum physics to me” would cost around €0.0003 with GPT-3.5.
  • Performance versus cost: GPT-4 offers better performance in terms of language understanding and text generation, thus justifying its higher cost.

Which to choose? ChatGPT 3.5 or ChatGPT 4?

The choice between ChatGPT 3.5 and ChatGPT 4 largely depends on the specific needs of your project or business.

Here are a few considerations that can help you make an informed choice.

ChatGPT 4 improves its UX with multimodal and extended memory

ChatGPT 4 really shines when it comes to multimodal interaction. If your project requires a combination of text, images and sound, as in an interactive educational application, ChatGPT 4 is the obvious choice.

For longer dialogues and in-depth discussions, ChatGPT 4’s extended memory allows you to maintain a coherent conversation over a longer period of time, which would be useful, for example, in an extended exchange.

Plugin integrations and online browsing with ChatGPT 4

One of the advantages of ChatGPT 4 is its ability to integrate easily with other technologies and plugins.

If you’re working on a complex project that requires several tools, such as a content management system or e-commerce platform, ChatGPT 4 would be more suitable. What’s more, its online navigation function is a major asset if your project requires access to real-time information.

Whether you need speed, precision, or more features, the choice between ChatGPT 3.5 and ChatGPT 4 will depend on your specific needs and budget.

The latest developments of ChatGPT in 2023

The recent update to ChatGPT, which is being rolled out in November 2023, marks a significant advance in the field of artificial intelligence a will certainly make ChatGPT even more essential in 2024.

One of the most important aspects of this update is the enhancement of multimodal capabilities.

Previously, users had to juggle between different threads to accomplish various tasks.

This update eliminates this need by combining features such as vision, code interpretation, image generation and web browsing, all in a single chat interface.

It will therefore be possible to analyze a document, do an online search and generate an image, all in the same conversation.

This represents a major step towards a smoother, more integrated user experience.
