Have you heard about OpenAI’s latest invention, the GPT-4 AI model? But what makes Chat GPT-4 different from its predecessors, like GPT-3 and GPT-3.5? Before diving into the details, let’s clarify something: Chat GPT is not actually a version of OpenAI’s large language model. It’s just a chat-based interface that’s used to interact with the latest GPT model. In this case, it was initially used to interact with GPT-3.5, and now it’s being used to interact with GPT-4.
There are many ways startups can use Chat GPT, but here’s the list of main differences between GPT-3.5 and GPT-4:
1. GPT-4 can remember longer conversations
The new GPT-4 AI model has a longer memory, which means it can keep track of more information and have longer conversations. This feature sets it apart from its predecessors, Chat GPT and GPT-3.5, which had a limit to how much information they could remember during a conversation. With GPT-4, the maximum token count is 32,000, which is around 60,000 words. That’s like having an entire play or short story stored in its memory.
The attention mechanism is what enables GPT-4 to keep track of such a vast amount of information. It can remember details from a conversation or a piece of writing that occurred as far back as 40 pages ago. With its longer memory, GPT-4 will be able to recall important details and maintain context better than its predecessors.
This feature is particularly useful in generating text, where GPT-4 can refer to events or details that were mentioned earlier in the piece. This makes the text more cohesive and easier to follow. With GPT-4, you can expect a more seamless and fluid conversation or writing experience.
2. Chat GPT-4 is a lot more difficult to trick
Another amazing feature of GPT-4 is that it is harder to trick. As we know, chatbots can be easily led astray and manipulated into saying all sorts of weird and unnerving things. But not GPT-4! It has been trained on a vast amount of malicious prompts that users provided to OpenAI over the past year or so, making it much better than its predecessors on “factuality, steerability, and refusing to go outside of guardrails.”
According to OpenAI, GPT-3.5 was just a “test run” of a new training architecture, and they used the lessons learned from that to create the new version. This resulted in a model that is “unprecedentedly stable.” OpenAI also did a better job of predicting GPT-4’s capabilities, which helps to avoid any surprises.
So if you’ve ever played around with a Chat GPT and managed to trick it into saying something ridiculous, you’ll be happy (or unhappy) to know that GPT-4 is much less likely to fall for those kinds of shenanigans.
With its enhanced ability to detect misleading prompts, GPT-4 is a major step forward in the world of artificial intelligence.
3. GPT-4 can interpret images
One of the biggest differences between GPT-4 and its predecessors, Chat GPT and GPT-3, is that it’s “multimodal.” What does that mean? Well, it means that GPT-4 can understand more than just text. It can also process images to find relevant information.
For example, let’s say you show GPT-4 a picture. It can not only describe what’s in the picture, but it can also explain more complex information related to the image.
OpenAI showed an example of GPT-4 explaining the joke in a picture of an oversized iPhone connector, but the real magic happens in its partnership with Be My Eyes. This app is used by people who are blind or have low vision to let virtual volunteers describe what their phone camera sees.
The possibilities are endless! Of course, GPT-4 might not always know everything about an image, but if you ask it the right questions, it can really flex!
4. Chat GPT-4 supports more languages
Chat GPT is becoming more multilingual. Although the AI industry is largely dominated by English, GPT-4 is breaking the mold by being able to answer thousands of multiple-choice questions with high accuracy across 26 languages!
This is a promising first step in the direction of facilitating non-English speakers’ access to huge language models. The fact that it can do so well in languages for which it wasn’t specially taught is nevertheless noteworthy, even though the testing criteria were translated from English and the questions might not represent everyday conversation.
5. GPT-4 supports “Steerability”
The new “steerability” function of GPT-4 is one of its coolest features. In essence, this means that the AI model may alter its behaviour at any time, which can be both incredibly beneficial in some circumstances (like when you need someone to listen sympathetically) and potentially dangerous if the model is intentionally made to behave in a particular way.
Anyway, what’s really exciting is that GPT-4 takes steerability to the next level compared to its predecessor, GPT-3.5. Now, users can customize the “classic Chat GPT personality” that had a fixed style, verbosity, and tone to fit their needs more specifically. Of course, there are limits to how much you can change the personality so it stays within bounds, but still, it’s a huge improvement.
For instance, suppose you wanted GPT-4 to converse with you as if it were a manager or professor. A more relaxed and welcoming tone, as if you were speaking to a close friend. With GPT-4 steerability, it can be programmed to alternate between several communication patterns depending on the user’s preferences or the situation.
The intriguing thing is that, unlike in the past, these new personalities will be built directly into the model’s code from the beginning rather than being suggested by the model and attempted to imitate.
How to get access to Chat GPT-4
Currently, if you have a free account with OpenAI, you can only access and interact with its GPT-3.5 model. To get the GPT-4 model, you will need to upgrade your account to ChatGPT Plus, a paid version of ChatGPT.
