OpenAI’s latest launch, GPT-4, is anticipated to completely outperform its predecessor, GPT-3. With all the details about this new model now out in the open, let’s see how these two models compare.

GPT-3 or Generative Pre-Trained Transformer 3 was released back in June 2020. Since its launch, GPT-3 has become one of OpenAI’s most popular and successful models.

Becoming the backbone of many AI applications currently on the market. Most notably, OpenAI’s infamous chatbot, Chat GPT, and Microsoft’s new AI-powered search engine Bing.

In recent months, many fans have been eager to witness the release of OpenAI’s next-generation multimodal model, GPT-4. And, it’s finally here!

Interestingly though, the new model has been kept tightly under wraps until now. It is not completely clear why OpenAI decided to be so secretive. Although, after Google’s recent mishap with Bard AI the apprehension about sharing any details prematurely makes sense.

So, now that we have a full picture of GPT-4, let’s explore how it compares to its predecessor.

What is the difference between GPT-3 and GPT-4?

The main difference between these two models is GPT-4’s new multimodal capabilities. According to OpenAI, GPT-4 will be able to “accept a prompt of text and images”.

This would be the first multimodal GPT model created by the AI firm and is an extremely exciting feature for anyone who is a fan of GPT-3.

Interestingly, there are also various similarities between the two models. Both GPT-3.5 and GPT-4 have limited knowledge of events that occurred after 2021. So, unfortunately, you’ll still have difficulty accessing up-to-date information.

Both models can also be used to perform natural language processing tasks, such as question answering and text summarization.

At the moment, a variation of GPT-4 is available through Chat GPT – if you have a Chat GPT Plus subscription. Otherwise, the next best way to access the model is by signing up for OpenAI’s API waitlist.

How much better will GPT-4 be than GPT-3?

At the moment, GPT-4 is only exclusively available to Chat GPT Plus members making it difficult to really assess how much better the new model is.

Thankfully, OpenAI has already released some details about how GPT-4 performs, which we will explore below.

Interestingly, both models will behave similarly when used for “casual conversation”. According to the developers, the distinction between GPT-4 and GPT-3.5 is very “subtle”. So, if you’re wanting to use the model to create your own personal chatbot, you won’t notice much here.

Despite this, OpenAI claims that GPT-4 is “more reliable, creative, and able to handle much more nuanced instructions than GPT-3.5”.

The main improvements really comes from GPT-4’s new image capabilities and its exceptional performance in exams. OpenAI has released a whole set of results comparing GPT-3.5 and GPT-4 exam abilities.

The biggest improvement is shown through both models’ performance in completing the Unifrom Bar Exam. GPT-4 managed to achieve a pretty impressive score, reaching the top 90th percentile. Whereas, GPT-3.5 only managed to reach the 10th.

GPT-4 vs GPT-3: Size

It is rumored that GPT-4 will be built using a larger dataset compared to GPT-3. According to NeuroFlash, GPT-4 will use 45GB of training data – 28GB more than GPT-3.

If true, we would expect the new model to deliver considerably more accurate results compared to its predecessor.
